Leslie Croker: 1978

Wednesday, February 10th, 2016

Leslie Croker came to work in the Chemistry Department of Imperial College in 1926 as a lab boy. In 1949 he was made a Laboratory Superintendent for the Physical and Inorganic chemical laboratories and later in 1956 for the entire Department of Chemistry.

He was greatly involved in the training of technicians at Imperial College (and in London in general) and talks about this in the video.

Snapshots: 1992

Monday, February 3rd, 2014

Predating the 1993 Undergraduate and Postgraduate Videos, seen in a previous blog, Lady Clare Ash (the wife of former Rector Sir Eric Ash) made a one-off video called Snapshots.

It was made to showcase just some of the then current research taking place at Imperial. I seem to recall that Eric Ash was about to go on an overseas trip to several countries, including India and that this was made to accompany his presentations. You’ll notice the emphasis on past Imperial Nobel Prize winners at the start of the video and a rather slow list of Imperial’s Fellows of the Royal Society towards the end.

Several areas of research from around the college were featured. Two Nobel Prize winners included were the late Lord George Porter (1920-2002) and the late Sir Geoffrey Wilkinson (1921-1996), both are seen working in their respective labs. Bob Schroter (featured in a previous blog) talks about his work with Camels; Steve Ley, formerly from Chemistry, discusses pest control, whilst Howard Thomas from St Mary’s talks about Hepatitis Vaccine.

Towards the end, we featured some of the first ‘vox pops’ in one of our videos, where current students talk about their experiences and views of being at Imperial College. You will see the first aerial footage of Imperial used at the start of the video.  This was provided to us by the (then) University of London Audio Visual Centre and was shot by them as part of a 16mm film they made for Channel Four Television. The video concludes with the former Rector himself, Sir Eric Ash, speaking direct to the audience with his views on where Imperial is today and what his vision is for Imperial tomorrow. This was shot in the old Rectors office up in the Sherfield Building.

Chemistry Teaching Videos: 1981-1993

Tuesday, May 21st, 2013

If you were studying Chemistry at Imperial College in the early 1980’s you would almost certainly have come across the series of teaching videos that we made. These were designed to provide a single definitive version of classic experiments carried out in the labs.  The way that it worked was that during a lab period students would have a number of ‘demonstrators’ who positioned themselves around the lab. They would then proceed to show the undergrads the way to achieve what was needed of them during the session. This was deemed to have flaws when it was discovered that very slightly different versions were actually being demonstrated. So, colleagues in the Chemistry Department asked for some of the experiments and also the techniques required, to be captured on video. These videos would then be made available to the students in the college library, prior to the lab session day and also at the start of the actual lab session via video players located around the lab. Starting 32 years ago, from 1981 to 1993,  11 of these classic experiment videos were made. Two of these: ‘Recrystallisation’ and ‘Using an Oil Vacuum Pump’ are on this page.

Making them was not always so easy. To capture the experiments we needed to be able to record, as much as possible, in ‘real time’. That is, record the action without stopping or having to then edit later. We needed to be able to try and capture what would have been demonstrated live in the lab. Also, when an experiment had started, it couldn’t always be stopped on a whim from me because I couldn’t get a good camera shot! So, we had to be able to record with several cameras and this meant shooting in the College TV Studio** where we had three cameras available. Shooting this way meant we could, as much as possible, run in real time; if we had rehearsed what was going to happen. So, using three cameras we were able to plan ‘blocks’ of the experiments that could be recorded before we had to stop and reset cameras etc. (more…)

Promotion: 3 – The Chemistry Department

Monday, November 5th, 2012

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! (more…)
