Bob Spence, was still going strong at 80

I have rediscovered a fascinating interview with Professor Bob (Robert) Spence, Professor Emeritus of Information Engineering & Senior Research Investigator in EEED. Today, Bob turned 80 and what better way to help him celebrate than bringing to your attention this interview from 1994. At the time, the TV Studio was still in operation and I was making a monthly video for a computer company called Lantec. A former TV Studio colleague of mine, Steve Bell, who worked for Lantec, asked me if we would make these videos for distribution to their company clients. The result was a programme we called Video Interface. This video is from Edition 13, from December 1994 and Steve is talking to Bob about his research work. I take no credit for the remaining text below, as it comes from Bob’s own personal web page at Imperial. I have added however a few links to videos I made with Bob on some of the subjects mentioned.

Bob’s research has ranged from engineering design to human-computer interaction and often with the manner in which the latter can enhance the former. Notable contributions, usually in collaboration with colleagues, include the powerful generalized form of Tellegen’s Theorem; algorithms for improving the manufacturing yield of mass-produced circuits; and, in the field of Human-computer Interaction, the invention of the first focus+context technique, the Bifocal Display (aka Fisheye lens). The novel Attribute and Influence Explorers provide examples of novel information visualization tools that have wide application, including engineering design. Interactive computer graphics allows the electronic circuit designer to sketch the familiar circuit diagram on a computer display. This potential was pioneered by Bob and his colleagues in the late 1960s and eventually, in 1985, led to the commercially available MINNIE system developed and marketed by a company of which Bob was chairman and a founding director. More recently, Bob’s research has focused on the topic of Rapid Serial Visual Presentation in which a collection of images is presented sequentially and rapidly to a user who may be searching for a particular image. This activity is similar to the riffling of a book’s pages.

 

spence 51 yearsAnd yet more news about Bob in April 2014 is that he has now achieved 51 years of service at Imperial College. See this article and scroll down to read about it. In the article Bob says “I’ve always said that if something is fun, it’s worth doing – and I’ve certainly had a lot of fun over the past 51 years.  Imperial has always had a fantastic community, and it boasts some exceptional students. They are the reason I continued to teach after my retirement – I never tire of working with them….”

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

Videos for Schools on YouTube

You can now find all of the remaining videos that were made for schools on the Imperial YouTube Channel. They are located in the Archive section along with other gems that are being added as time permits. I’ve included two of them in this blog, but do go to YouTube to be able to see them all. One video that stands out as an example of science and technology is the one with Denis Smith on Water Power and the Industrial Revolution. We made the video in many parts of the UK at various (then) working Watermills, Pumping Stations and so on and it was a real joy to make too.

The two pictures show Dr Denis Smith at (above) Abbeydale Industrial Hamlet in Sheffield and (below) and at a lock on the Kennet and Avon Canal.

UPDATE April 2018: I’ve only just received the sad news that, after a long illness, Denis died last November.

Here then is that video on Water Power and the Industrial Revolution.

The last video we made for schools was on the subject of the weather. This video was presented and written by Francis Wilson, and ex Imperial student and who, at the time, was presenting the BBC Breakfast show weather each day. Here is Weather on the Move.

New to the Blog?

If you are new to the blog or perhaps arrived via the Alumni web page, you might have missed some previous gems. If you go back further to earlier entries you will find some memories of Imperial College captured on videotape. One such recording is the only interview we have with Victor Mooney (Died on December 27th 2012 aged 89), college catering manager from 1953 to 1985.

Southside Royal opening taking place in the Upper Refectory,  Southside

He was a major figure in college life, especially with the student’s phrase “Going for a Mooney”, which meant going to the refectory for a meal of some kind. Do you remember the Upper and Lower Refectories in Southside? How about WAITRESS service in part of the Refectory in Sherfield? And also a time when the JCR eatery was still called the “Buttery”.

I have now managed to clean up the quality of the recording which was made in November 1979,  just prior to us going into full colour. Here’s Victor Mooney, in the College TV Studio, talking to STOIC regular presenter Dave Ghani.

If you have any film or photos of the college eating places in use during the years before say 1970, then please get in touch. Please also add comments or memories of eating at Imperial.

Promotion: 3 – Chemistry 1981-1985

In “Promotion: 1” (March 2010), I mentioned the Civil Engineering and Chemistry Departments. In June 1981 I was asked to take on the task of making a promotional video for the Chemistry Department.

The Chemistry Building in March 2002

This was intended to promote all aspects of what the department did and to assist in the recruitment of new students. I also recall it being shown at Open Days which seemed obvious . Two members of the staff were appointed as ‘producers’ so most of the content and the wording of the voiceovers was decided for me. Looking back at the video over 30 years later it has too much in it. The history section seems unnecessary and there’s too much detail in the various elements featured. It runs for nearly 20 mins which is about two thirds too long in todays modern YouTube video world. Leave them wanting more is the theory, not wanting to leave the room as soon as the video has eventually finished! This was one of two videos made for the department, the second being made four years later in July 1985. It’s worth noting that both of these videos were made using our original colour camera. It needed massive amounts of light (as mentioned in the Library video) and suffered ‘smearing’ on highlights, the colour itself was none too brilliant either!

The second video was also far too long but did, thank goodness, have Professor Sir Geoffrey Wilkinson in it. He appeared because he was then head of department. Being a Nobel Prize winner it was considered important and prestigious to feature him. I said thank goodness because it has given us the only interview recorded with him whilst at Imperial, an archive gem. Like the first video in 1981 I had little control over the content. It seemed that almost everything including the kitchen sink appeared in the video. I truly ‘cringe’ when I watch it, especially the Kensington Gardens sequence! One of the few times I managed to get my way was on the intro sequence. I used so called ‘production music’ rather than music created by a family member as in the first video. The video does use, for the first time, electronic effects. The multi-picture sequence later on and during the opening where the image slides down were all very new at the time. Now, these are common place and all achievable on a computerised edit suite, but we had a dedicated box to do it that cost thousands of pounds.

The original Dalby Court in 1985

On an historical note, the first person you see talking is located in a lovely garden area…that’s where the ‘blue box’ Faculty Building is now standing! You’ll also see Princes Gardens, as it then was, in the summer of 1985. Between 1981 and 1993 I made around 10 teaching videos that were used on various ‘lab days’ to show the students how do undertake the experiments they had to do. It was considered more effective to show one correct version of an experiment, rather than several slightly different versions by several different people based around the labs. I’ll try and get some of these on line soon. Maybe you had to do one of these experiments whilst at Imperial?

Also, if you are featured in any of these videos do let us know. The two still photos were by my former colleague Neville Miles, who like me, helped to capture some of the history of Imperial College in the many photographs he took over the years.

Life Science Library 1979

Queens Tower steps “opening sequence”

The first programme we made in colour was a guide to the Life Science Library. That was 33 years ago in August 1979 and colour was so new that we didn’t even have a colour logo caption at the start, in fact it’s our original black and white logo. Interestingly, the video is a great snapshot of what libraries looked like and how they operated at that time. Card indexes were still the norm with microfiche readers being a new addition. There is also mention of having a literature ‘computer search’ carried out at a cost of around £5, a cost which was probably considered high at that time and would have been carried out by a librarian for you. One of the great advantages of us moving into colour was the fact that we were able to edit. Until then it was possible, but difficult, and also in black and white. The video required a lot of different shots, like close-ups of index cards, so editing was an essential part of the production, in fact, without decent editing facilities this programme could not have been made.

Lots of lighting was needed for the camera

Because we were going to cause some disruption in the library, where possible, we shot in the evening, or at least after 5pm. As you can see from the photo on the left, we also needed light..lots of it too. Our early colour camera was happy with external situations, but inside it required rather a lot of light to get good images. The library, at that time, was rather lower in light levels compared to today and there was no way we could cope without adding some extra lighting. Our biggest problem was finding mains sockets anywhere near the rows of book shelves. You tend not to need mains sockets when looking for books! Like most of our videos, we sometimes needed (and still do need) ‘rent a crowd’, so see if you can spot me appearing twice in the video. Also note a major change to the feel of the South Ken campus from when this was shot in 1979. See how empty it is soon after 6pm when the external footage was shot.

The video style is a bit 1970’s, mainly because that’s when it was made. I can’t recall under what circumstances the video was due to be seen, but I think it was designed to be viewed in the room that had been designated for watching videos. This was one of the small rooms called a Carrel around the edge of the library in which a monitor and video recorder had been installed. You’ll hear reference to these Carrels in the video. Listen out too for the mention of photocopies, there were only two in the whole library at that time.

Mark Caldwell when at DW in Germany

The presenter of the video was Mark Caldwell, a former STOIC chairman from the mid 1970’s. Mark is now living in Germany where he used to work for the world radio division of Deutsche Welle. From time to time I can could hear him presenting items live over the air and I thought how far we had come since his time with STOIC  at Imperial, only a few years before.

I’ve also noticed that, as this was the first video we made in colour, we still used the original TV Studio caption. This was the caption used up until this point, I hadn’t come up with a colour version at this time!

October 2012 -The Blog returns

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.

Events: St Mary’s Merger Ceremony 1988

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!

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
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

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
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

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

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.

Lord Penney interview in 1971

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.

Nobel Laureates

One area where the archives are sadly lacking in both audio and videos recordings is on the subject of Imperial’s Nobel Laureates. And, as always, my appeal is to anyone who may have something to boost our collection, in either audio/video/film and so one. This current entry will focus on those Nobel Prize winners for whom we have recordings.

Professor Dennis Gabor
Professor Dennis Gabor

In 1948 Dennis Gabor (1900-1979) joined Imperial College as Reader in Electron Physics, he was appointed FRS in 1956 and Professor of Applied Electron Physics in 1958, retiring from the Chair to become Professor Emeritus and Research Fellow in 1967. His experiments on holography began in the 1940’s and on the flat television tube in the 1950’s. The model for his flat TV tube is held by the college archives. I met him only once when he was in our TV Studio to watch a film. On leaving, he spoke to me about the Sony colour TV we had. He said “Ah you have a Sony colour television” to which my reply was along the lines that the Japanese were very clever with their technology. He put his hand on my shoulder and told me that the principle of its workings (the TV’s single electron gun cathode ray tube) was something that he had proposed and suggested, but for which funding could not be found at that time and that the idea went to Japan and was used in those Sony televisions.

For the Invention of Holography, Gabor was awarded the Nobel Prize for Physics in 1971. A few months later on 22 February 1972 Gabor repeated his Nobel lecture, but this time for a special audience at Imperial. For us we are fortunate that a sound recording was made of the event. It’s not amazing quality, but I’ve done what I can with the sound to help improve it and also slowed down the tape that was clearly running too fast when I played it back. It’s introduced by the Rector at the time Lord Penney and there’s a vote of thanks by a departmental colleague, Professor Colin Cherry. That itself is interesting as the only sound recording we currently have of Cherry speaking at Imperial ++. Even more interesting are the references by both Penney and Gabor to power cuts. This was because of the 1972 Miner’s Strike and the so called “three day week”. Imperial, like all other places was subject to limited mains power during the day and at specified times the entire campus would be plunged into darkness….even Nobel Prize winners!

In 1981 I made a promotional video for the department of chemistry. A section within the video included one of the current students talking to Professor Sir Geoffrey Wilkinson (1921-1996) in the office. At the time, Wilkinson was head of department. It’s a pity that this is such a general video and that we never recorded anything more in-depth with him. I’ve been able to go back to the original ‘rushes’ (that is the original videotape shot at the time) of this interview to improve quality slightly, but it was made 30 years ago on our original low-band U-matic colour recording system (a single-striped faced, vidicon tube camera).

The only other recording of him was made in February 1992. this was for a video called “Snapshots”. The video brought together some of the current research being carried out at Imperial and showcased it for, primarily, an external audience. This sequence however is very short indeed and is the only record we have of Geoffrey Wilkinson in his research lad. And, for what ever reason, I don’t seem to have the original rushes any more so can’t see if there was anything else recorded at the time.

Finally we take a look at Professor Lord George Porter (1920-2002). He became chairman of the Centre for Photomolecular Sciences (and Professor of Photochemistry) at Imperial in 1987. He received a Nobel Prize in Chemistry in 1967. He was a former Director of the Royal Institution (1966-1985) and this was when I first met him. That was during the 1966 televising of the Christmas Lectures with Eric Laithwaite (see Laithwaite blog entry). This first recording is fun because we recorded it in his lab in the basement of the Beit Building. It’s full of lasers, for which I’m sure he should have been wearing safety glasses.

George Porter A 2/8/1995
George Porter’s 1995 Singapore lecture with Martin Sayers on cameras

Lastly, a unique recording of Lord Porter. This was not actually a planned videotaped lecture as such. In August 1995 he was asked to give the 10th Lee Kuan Yew lecture in Singapore. As he was unable to attend in person it was suggested he gave the talk via a videoconference link. We re-arranaged our TV studio to allow it to link into our videoconference system. You may spot him looking down at a monitor which was showing him the audience in Singapore and at one point talking to Martin Sayers behind the camera to confirm timings. He was very easy to work with and like Eric Laithewaite skilled in presenting on TV and film.

Prior to the day, he telephoned me several times to discuss details. He had a habit (so I was told) of sitting in his garden in summer months and making calls on a cordless phone. However, he was always at the limit of range of the base unit and was barely audible, so the call was full of hiss and crackle. It was only by chance that I happened to put a videotape into a recorder to make a record of the event and I’m glad I did. So here is the lecture, given live to Singapore, on a very hot London day on 2 August 1995. And because it was so hot, we left the usually noisy air-con unit switched on and you may hear that in the background.
