October 2012 -The Blog returns

4 October 2012

Blog update

I’m very pleased to be able to say that the Video Archive Blog has returned. I took early retirement in January of 2011 but have recently been asked to restart and update my entries. So, we can look forward to more videos that are currently held in the video collection. I’ll also be trying to sort out and access the 15 year archive collection from STOIC the Student TV of Imperial College. That collection dates from about 1970 to 1985, or there abouts.

Working from home (and sometimes from Imperial) I can now devote as much time as I wish to this Blog. There are so many videos just waiting to be seen again. In fact I already have a few Blog entries awaiting the click of a button to make them live. The most time-consuming thing is the transfer of videotape into a digital format. What I’m currently doing is to make a DVD in maximum resolution of the video, before creating an on-line video held on the server. The DVD is stored along with the original videotape to make access easier. But the problem is that a 30 minute video takes 30 minutes to copy into a new format. That can take a lot of time!

Anyway, keep looking to see what’s changed or been added and let me know if you have any special requests or material that would be of interest to Imperial College.

30 years ago this week…

Colin Grimshaw

14 December 2010

This is an additional and brief entry to mark the recording of a video I made 30 years ago this very week. The video was “The Office of the Professional” made with, and for, Professor Bob Spence from Electrical Engineering. You’ll find this video and others in the section about Bob’s work, but I thought it worth repeating. I saw Bob recently and we both recalled the making of the video and how complicated it was. For example, the various TV screens seen running were in fact fed from different video players, so making these all run in sync was not easy. In fact, along with the recorder that was actually recording the video from the camera, we had 3 machines all needing to be run at the same time. This was early days for us and our colour camera (yes camera, as we had only one) which needed a lot of light to give good pictures.

The video was shot during this week in December 1980 and edited, after the Christmas holiday, in January 1981. Bill Buxton in his 2007 book Sketching User Experiences is quoted as saying, in reference to the video that this “is the first example of an envisionment video that I am aware of” and that it was “remarkable for its insights”. As I have already detailed in the previous full entry about Bob, the office desk that was constructed was faced in cardboard and green felt. One oversight was perhaps the telephones, we never attempted to change these to anything futuristic, so they look a bit odd now. The video also captures parts of the college long since changed and Alumni may remember: the main entrance, the steps and the original walkway going towards Electrical Engineering. These shots were taken on a dark and wet December afternoon back in 1980.

Professor Robert Spence, passed away on Friday 20th September 2024, at the age of 91.

Promotion: 2 – Mathematics

Colin Grimshaw

8 December 2010

This is the first year of the Video Archive Blog (it started in December 2009), so, as we’re nearly in 2011 I thought we’d reach back 30 years to see what was going on at that time. In 1980 non-broadcast video was still considered a new and exciting thing and we’d just moved into colour operation too. Maybe it was the whole idea of creating your own colour TV programme (which you could do if you had the right equipment) that encouraged people? So, in 1981 I was asked by the Department of Mathematics to think of ways to promote the department. It was decided an approach should be taken to discuss Mathematics in general rather than the department alone.

Lynda White, then Admissions Tutor in Maths, lead the decisions over who should appear and what they might say. She also appears at the start of the video standing outside the maths department on Queens Gate – as can be seen in this promotional photo taken at the time. Also, you’ll hear her asking some of the questions to her academic colleagues during the video. I was interested to see that we referred to everyone, except Lynda White, as just Dr or Professor and never used their first names on the captions. These days it now seems strangely formal. The only time that students are actually seen is during the opening sequence and I also spot some shots taken from the 1979 promotional video for the Lyon Playfair Library (that will be a separate blog entry where you can see the whole video). Worth noting too is that in those early days the video camera was separate from the recorder, which can be seen on the pavement. Camcorders came much later on.

Here then is the video we made. Looking more than a little dated now after 30 years and I think I’d be asleep by now if I had to sit and watch it all the way through! I can’t believe we actually had a list of courses and options being read out as part of the video. We seemed to spend a lot of time not really talking about Imperial. We did have discussions again along similar lines of promo videos but decided that a different approach should be adopted. We did this by creating a series of some 20 videos in conjunction with the maths department and the London Mathematical Society (more on these coming soon, along with all the videos we made -some 18 of them-going online).

New College Phone System: 1984

Colin Grimshaw

19 November 2010

In the summer of 1984 I was asked by Peter Burridge the Telecoms Manager, to make a special video to alert all members of Imperial College to the fact that we were about to put into service a new electronic telephone exchange. Until this time we had two systems running side by side: an internal automatic exchange and an external (BT) manually operated switchboard.

1950's Automatic Telephone Exchange — 1950’s Automatic Telephone Exchange

The original internal exchange, installed sometime around 1959, was located in the basement of the Royal School of Mines, whilst the external switchboard was installed in the Sherfield Building around 1969. This was probably to coincide with the opening of the building that year. For those only familiar with how things operate these days, the old system now seems very ancient. It required two telephones on a desk, internal and external. You called via the internal exchange with very old dial phones (in some cases), whilst to make an external call you picked up the receiver of the other phone and waited for the operator to answer.

You then had to request an ‘outside line’ and from there you could dial your call. All incoming calls to Imperial were answered by the operator and then put through to the extension in question. There were no connections between the two systems! So if a location only had an internal phone there was no way to contact them from outside of the college. The internal exchange catered for some 2,500 extensions whilst the external catered for 1,500 extensions.

statesman handset — The ‘new’ Statesman telephone 1984

The new system was deemed so “new” that training sessions were put into place at various locations around college. These were designed for either staff or students and some even took place in the Great Hall. It may seem odd, but at that time most secretaries, for example, were using normal electric golf-ball typewriters and few people had contact with computers unless they were academic. So, having to press button combination’s to achieve things like two way calling or call transfer had some people a bit stumped, thus the training sessions were arranged. As this concerned all of college there was great publicity and this can be seen from this mid-summer edition of the student newspaper Felix from 17 August 1984 (pages 4 & 5).

The colour stills of both the 1950’s exchange and switchboard are taken from the videotape I shot. So far, I’ve not located any other images of, what was, a major part of the daily unseen operation of Imperial College. I suspect that these sequences in the video may have been the first time that some people had seen any of these background services operating. I was also one of the first to experience the new system.

A few weeks before operation began I was asked if I’d wait by my current internal phone at around 6pm one evening whilst it was manually switched from the old to the new system. I then received a call via the new exchange to test all functionality and quality of sound. The rest is now part of college history as we all take the new systems as part of normal daily college life. But is was just a little bit different when you picked up the external phone and knew the person on the switchboard and had a short conversation before saying…”can I have an outside line please?”.

Commemoration Day

Colin Grimshaw

18 October 2010

As we celebrate yet another Commemoration Day at the Royal Albert Hall I thought the time was right to bring you the few recordings we have from earlier years. At the end, I’ll mention technical challenges involved with the transfer of the first two recordings onto modern formats.

Although you’ll find this first recording elsewhere I’ll include it again for completeness.
The October Commemoration Day graduation ceremonies recall the visit made to the College by King George 6th and Queen Elizabeth in 1945, on the centenary of the foundation of the Royal College of Chemistry, Imperial College’s oldest forerunner. King George said: “You students here assembled – men and women who soon will be going out from the Imperial College to your work in the world – have not only an opportunity but also a responsibility greater than men of science have known before. To you, I say: Regard your knowledge and your skill always in the light of a trust for the benefit of humanity, and thereby ensure, so far as in you lies, that science may never be put to uses which offend the higher conscience of mankind.”
For those unfamiliar with King George 6th, he battled throughout his life with a nervous stammer and his attempts to overcome this during the speech are obvious with long pauses between sentences.

From 1945 we jump to 1952 and a recording that, so far, I have no idea exactly why it was made. It features Karl Compton who was a prominent American physicist and president of the Massachusetts Institute of Technology (MIT) from 1930 to 1948. In 1948 he resigned his post as President of MIT and was elected president of the MIT Corporation. He held that position until his death on June 22, 1954, some two years after this sound recording was made. Compton was awarded a fellowship in 1949 but was unable to attend, but in 1952 he was special visitor and collected it then. Interesting references are made to key players in college life at that time: Chairman, Viscount Falmouth; Rector, Sir Roderic Hill along with Sir Henry Tizard, Sir Richard Southwell and Sir George Thomson. There is only part of the introduction by Viscount Falmouth to Karl Compton on the original tape, so it will sound a bit truncated. At the end, Compton reads greetings to the Imperial community from the President and also the Chairman of MIT and the American national anthem is played. Could this be why it was recorded?

Finally, we have something visual in the form of a 16mm colour film shot in 1973. Robert W Sarnoff was President of RCA (Radio Corporation of America). He was the eldest son of broadcasting mogul Brig. Gen. David Sarnoff, he followed in his father’s professional footsteps throughout his career at NBC and RCA. The citation for Sarnoff indicates that he was the benefactor of the Imperial College Haldane Music Library. A year later in 1974 Sarnoff married Metropolitan Opera diva Anna Moffo, so maybe opera was his interest as well as being the music library benefactor? As I understand it, Sarnoff himself paid for large parts of the 1973 Commemoration Day ceremony to be filmed in colour and with sound. Lord Flowers was Rector at the time and is seen in this current extract. This is the earliest moving picture record the college has of one of its ceremonies and it’s thanks to Robert Sarnoff that this happened. One of the greatest achievements by RCA and Sarnoff in particular was the development and introduction of colour TV in the USA. He was the first person to be officially televised in colour at the dedication ceremony of NBC’s new Washington, D.C. facilities on May 22, 1958. For those interested, you can see an amazing videotape that has been rediscovered of this 1958 event. The program represents the earliest known colour recording discovered to date.

The first two sound recordings could have been lost for ever had we not transferred them onto modern formats. The 1945 recording of King George 6th is held on 78rpm shellac discs which are very delicate and will break if dropped. I had these transferred by the National Sound Archive a few years ago. Although, in theory it’s easy to copy these discs, using the correct pick-up weight and stylus is essential. Using a modern LP stylus will simply “bottom’ into the disc’s groove and produce more scratch and crackle then actual sound and can damage it too.
The second recording IS interesting. I discovered that the recording tape used paper as the backing, rather than a form of plastic and its manufacture probably dates from the 1940’s. The oxide was also very basic and looked more like gunpowder than anything you could record sound on! Transferring the tape was also a challenge as I had to run the tape very slowly because it was sticking to itself like a reel of sticky parcel tape. A lot of background noise will he heard and I’m still amazed I managed to get anything off of it anyway.

I hope you have enjoyed listening to our recordings of Commemoration Days from the past….unless YOU have something we don’t know about?

Events: St Mary’s Merger Ceremony 1988

Colin Grimshaw

21 September 2010

On the 19th October 1988 the beginning of the mergers with the medical schools started. This was the merger between Imperial College of Science and Technology and St Mary’s Hospital Medical School, located just north of Kensington Gardens and Hyde Park at Paddington. The end result of the mergers was the formation of the Faculty of Medicine.

St Mary's campus — St Mary’s main entrance arch

To my knowledge this is only the second time that the college’s Great Hall has played host to a royal event. The first of these was the opening of the building (then called College Block and subsequently Sherfield Building) and the hall itself by HM the Queen in 1969. The hall was packed as you would imagine and that didn’t leave all that much room for the two cameras and tripods we had proposed for the live recording. We were also limited in terms of man-power so my colleague Chris Roberts operated the main camera whilst I located the second camera next to where I had the vision mixer and recorders. This meant that I could not only cut between the cameras, but also operate the second camera to change the shots slightly. What I could not cope with was the fact than when people stood up, they almost blocked the shots from the camera next to me.

The ceremony starts with the fanfare “St Mary’s”. There are then several musical interludes during which you’ll see a very young Richard Dickins and these 22 years later I must apologise to Richard because we got the spelling of his name wrong on our end credits. But, it’s a wonderful record of music from the college symphony orchestra playing Walton’s ‘Crown Imperial’. Also the late Eric Brown conducts the college choir with music from Carmina Burana. And finally in terms of music you’ll hear the electronic organ that’s located within the hall. Princess Anne, (The Princess Royal) as Chancellor of the University of London presented the Chairman of the Governing Body (Sir Henry Fisher) with a specially bound copy of the Imperial College Act and its revised Charter. The Imperial College Rector at the time was Professor (later Sir) Eric Ash.

As always, I’ve had to tweak the image on the video to make it look at bit better. Technology has advanced a lot since this was recorded and the lighting levels required to get good images is a lot lower these days. The Great Hall have never been fantastic for shooting video unless extra light is thrown at the stage area and that then leaves the audience rather dark, whilst the wood panels around the hall make a very warm image when light bounces off it. The whole video is around 45 minutes in duration.

Creating this blog is a sticky business!

Colin Grimshaw

2 September 2010

Since the start of this archive blog people have asked me various things about the videotape collection. Questions range from: when did the collection start; how many tapes are there; and what formats of tape do you have. So, I thought that just for once I’d write an entry without an actual video in it. Some questions I’ve been asked are answered in the “about this video archive blog’, but I’ll go through them again anyway.

Some of the 700+ tapes in the video archive

The earliest videotape (one inch ‘A’ format) dates from about June 1970 and is on our original videotape format made by the American company Ampex. This company invented the world’s first commercial videotape format back in the mid 1950’s (2 inch Quadruplex). So, our oldest tape was made only 15 years after the invention of videorecording itself. Sadly, playing these tapes back is slowly becoming a problem. Equipment is no longer accessible on campus to run some of the formats we have, but it is possible to use commercial facilities (at a cost). Recently, the earliest collection from the student TV service (STOIC) came under our access.

The Ampex one inch open spool 'A' format tape — Ampex ‘A’ format tapes have gone sticky

I’d forgotten just how many of the original one inch videotapes they still had. There are gems yet to be seen, dating from the early 1970’s through to about 1980, in fact their collection now has more one inch tapes than we do (many of ours are long gone). Anything of importance was transferred to another (the latest at the time) videotape format, but some items (mainly STOIC’s) remain, frozen in time, awaiting that day of playback once more when finances allows us to transfer them into a new digital format.

Playing these early tapes back has recently become a problem anyway. There is an effect called Sticky Shed Syndrome which means that the binder, which sticks the oxide onto the plastic tape, is breaking down. What appears to be happening is that the binder is taking in moisture and going sticky. It’s SO sticky in fact that when tapes are run, the oxide and binder come off the plastic tape and stick to all parts of the videorecorder that the tapes run past. After only a few moments of playback there will be a very loud screeching noise followed by the video head clogging and the machine grinding to a halt. If you put your finger onto the guides inside the machine it will be sticky and covered in tape oxide and a sticky goo.

Oxide is badly shedding from magnetic tapes — Oxide is shedding from magnetic tapes

In the recent blog entry called “seen and gone” I found some old audio recordings of the soundtracks of erased videotapes. These audio tapes also suffered the same problem of shedding oxide. When I started to play them the oxide came off the plastic, as you can seen in the photo. My fingers can be seen through the plastic tape. The one good thing was that whilst running the tapes through the recorder I was also copying it onto computer to then go onto disc.

The U-matic videotape format suffers too

These playback problems have happened because some tape manufacturers got various chemical mixing formulas wrong. It was only in the mid 90’s or so that the problem was fully appreciated. There is only one way around the problems of playback. The tapes, audio and video, have to be baked. That is, the tapes have to be heat treated at something like ±50 oC for a few hours or more. This draws the moisture out, allowing immediate playback to get the material onto another modern format. The temperature used is critical, too high and the ‘Curie point’ can be reached and the tapes automatically erased, or at least the magnetic properties will be lost and thus the recording data will be gone for ever. So there are problems and dangers anyway with this method of recovery!

The various tape formats we have to work with sitting on the edit suite desk

We are therefore faced with a slight problem of playback, even with tapes still in use today like the U-matic system. Most of the tapes seen on the shelves in the top photo are of this format and many are causing playback problems. I’ll be experimenting with heat treatment soon to sample a few tapes for transfer. In most cases I’ll put these onto DVD, assuming they’ll play back okay after treatment. Today, we have many tapes formats as can be seen in this last photo. We’ve gone through: One inch open spool both low and high band; U-matic low and high band; Betacam and now DVCam. Also we’ve encountered half inch open spool, Philips cassette, VHS and so on. With some 700 tapes now being held in the collection, the question is how long will we be able to play back any of the many formats of videotapes that we have?

Seen and Gone: Two

Colin Grimshaw

15 August 2010

So now we come to the second Seen and Gone and this is when we get to see something interesting (and yes I do mean see). In December 1971 STOIC showed their Christmas edition of the then regular news programme Topic. I’ll try to recall the background to this programme if my memory serves me well!

Although by this time we had two videotape recorders in the studio, the programme was shown live to the JCR (Junior Common room), whilst the recorders were used to replay some inserts into the programme (maybe one did also record I can’t remember). At this time it was still not possible to easily record items outside of the studio so some cunning ideas came into use. To enable STOIC to capture external events an 8mm cine camera was used. The footage was then edited together and a simple background audio track of, for example, street noise, was created to play in the background. These inserts were then run into the live programme whilst one of the presenters did a voiceover. In later years a magnetic sound stripe was added to the film to allow sound to be pre-recorded in synch. Things didn’t always go to plan however, the splices in the film sometimes broke during projection or whilst being made ready to be shown. On one occasion a splice broke on the film that was going onto the take-up reel, the easiest thing to do at the time was to ignore it and therefore the film simply spooled directly onto the control room floor in a large pile. This edition of Topic was a good example of where things could and did go wrong. You’ll hear two situations where something happened and the presenter is called on the phone from the control and asked to ‘pad’ until it’s resolved. I thought it was fun if I left those in what you’ll be hearing.

Now, I have called this Seen and Gone, but that’s not strictly true in this case. When I found the audio recording I remembered several spools of 8mm film. These are the original films used to insert into the programmes until portable video became available. They have sat there for 40 years waiting to be seen again. However the videos which they appeared in have long gone. But, in this case I had the soundtrack! So, what you are about to see is the recreation of a lost programme from 40 years ago. I remembered too that I had some photos of STOIC setting up and using the studio at Christmas…..bingo, it was THE same programme I had on audio. So, I’ve been able to use them and the 8mm films to insert at the appropriate places. There does appear to be one film missing and you’ll only hear the commentary and background sound effects. I discovered photos of Lord Penney being interviewed and those too are from the same programme.

So, you’ll be hearing and/or seeing: Guilds Motor club A-Z rally; NUS day of action; Silly Football in Hyde Park; Morphy Day rowing, the London to Brighton vintage car rally and the Lord Mayor’s Show. An interview with Lord Penney (then Rector) was prerecorded and I used the three photos taken at the time of that. Former Union President Piers Corbyn is included and I found a photo taken of that as well. And there’s an added bonus too. Many of the 8mm films were shot with normal Kodak 8mm film stock, so for the first time ever these will be seen in colour. Other items were shot using black and white film. So here is my recreated Christmas Topic from December 1971 with mistakes and technical breakdowns left in.

Seen and Gone: One

Colin Grimshaw

16 July 2010

The one big disadvantage with videotape is that it can be erased. All too often a recording is considered of no further use and the tape is either thrown away or erased and re-used. But back in the early 1960’s and 1970’s it was cost that was the concerning factor. I recall that the first open reels of Ampex one-inch tape that we used cost around £30 each at that time, something more like £300 in today’s money. So, there was a desire to save money and therefore reuse old tapes again. Recently, I remembered that I had some audio tapes that I’d made from the sound tracks of various programmes and that these programmes had long since been erased. So, I collected them all together and took out one of my faithful old reel-to-reel tape recorders sitting at home. What did I have and was there anything of interest? Well yes, very much so, it turns out. I had a few sound tracks of videos made with the student TV service STOIC for example. Always a good source of college history I listened to what the content was and to whether there might be a gem or two. On a live Christmas 1971 edition of their first news magazine programme TOPIC, I found interviews with Lord Penney (then Rector) about the recent 1971 NUS “Day of action”. This now takes the number of recordings we have of him from 4 to 5 and will be placed into the college archives. We’ll be seeing that programme, in ‘recreated’ form, in the next Seen and Gone number 2.

I also found a soundtrack to a series of programmes I made with Sinclair Goodlad. One of these programmes, which is a May 1972 interview with the very first student counsellor, still exists on the original one-inch videotape, although it has never been transferred to any modern format so at present we’re unable see it. The photo of Sinclair is from 1967 and was taken during one of his “20 minute talk” sessions he ran on Wednesday afternoons in Electrical Engineering. Behind him can be seen our very first videotape recorder, an enormous machine made by Philips and full of very hot valves.

A nice piece of timing in my discoveries was an interview with Lord and Lady Flowers. This was recorded after one of their famous Beer and Bangers parties held in their flat at 170 Queen’s Gate. On the 20th October 1976 James Sinclair from STOIC went along with the portable videorecorder kit to ask a few questions about why the event takes place. It’s a pity that no photos were taken at the time.

Felix is the student union newspaper with its first edition dating from December 1949. The editor at the time of this next interview was Clive Dewey. There is mention of a colour edition and I think he was the first editor to achieve this. I recall Clive doing some things with STOIC as did another former Felix editor Mike Williams. Again James Sinclair is the interviewer in this 7th October 1976 recording.

Next time you’ll get to hear, (or is that see?) the 1971 Christmas edition of Topic, with some special surprises after 40 years of being lost….

Rectors: Lord Brian Flowers

Colin Grimshaw

28 June 2010

Brian Flowers (1924-2010) became Rector in succession to Lord Penney in 1973. Then Sir Brian, he quickly became popular and approachable with staff and students alike. The now famous ‘beer and bangers’ parties held by him and Lady Mary Flowers (1921-2016) were hosted in their flat at the Norman Shaw designed building at 170 Queens Gate. This gave many people the opportunity to meet both of them and in particular to gain access to one of the most wonderful buildings owned by Imperial College. Five years after he became Rector, I shot a video with the student TV service STOIC, this was the first time a video had been shot in 170 and in particular up in the Rector’s flat (a photo taken during this event is at the bottom of this entry with me in silhouette on the extreme left hand side).

Although you’ll find a version of this first video posted on other Imperial pages I think it’s important to repeat it here and set it in context. Also, this is the full version which includes an interview with Lady Flowers. At that time, what eventually became the ‘family room’, was then the music room with a grand piano occupying most of the space. I thought it might be fun to ask him to sit at the piano for the first part of the recording which was about him, his work and what the Rector of Imperial did on a day to day basis. As always he happily agreed and so that it what you’ll see first. Because Mary Flowers was so much part of his life at Imperial, the second part was shot in the Sitting Room with them both talking about their “Imperial life”.

As always, I’m including something that has only recently been re-discovered. On the 20th January 1984 STOIC recorded a studio interview with Brian Flowers who, by then was Lord Flowers of Queen’s Gate. Unlike other interview with him, he not only talks about his work as Rector, but as the then Chairman of the CVCP (Committee of Vice-Chancellors and Principals). He also touches on obtaining his MA at Cambridge, being a visiting professor at MIT in the USA and his earlier job at the Atomic Energy Research Establishment. Also discussed was something that was new at that time, Imperial College spin-out companies.

Finally, the last video shot with both Brian and Mary Flowers. For the 2007 centenary I had proposed a series of videos with all living Rectors. And we all felt it appropriate that we should interview both Brian and Mary Flowers at what was, their home for 12 years, 170 Queen’s Gate. In this extract, they discuss having a good working and social relationship with the student body and what was their most memorable event in the college calendar, the beer and bangers evenings. Here they are in the Council Room in 170 Queen’s Gate.

Recording in the sitting room of the Rector's flat at 170 Queen's Gate in 1978 — 1978 recording in the sitting room of the Rector’s flat at 170 Queen’s Gate

I’d been a regular visitor to 170 during their 12 years at Imperial. On one occasion Mary had persuaded me to provide and run some background music for her fund raising fashion show event for the day nursery, as mentioned in the last video. Nothing too ordinary was this event though, as we had Princess Anne attending…and without warning Mary suddenly insisted I was introduced, sadly no photo was taken. My last meeting with Brian Flowers was 2 years ago when Mary asked me if I could call in and see them, because she wanted to ask me a favour. They were, by now, living in north London and so I called in one lunchtime and had the most hospitable lunch with them sitting around the kitchen table and chatting about Imperial and all the latest news (and gossip too). And that takes me back to the kitchen at 170 and the many times Mary insisted on making me a cup of tea, if I were ever there, for some reason or another…..
