After two years in Dental School, Len realised that looking into a camera viewfinder was much more interesting than looking into people's mouths so joined Paramount Pictures as a trainee.
Joining Studio Film Laboratories in 1952 for further training in laboratory practice, he fell in love with the place and continued to work there for over 40 years.
After involvement in sensitometry and chemical control, grading, printing and processing Len was appointed Director and General Manager of Studio Film and Video Laboratories in 1980.
Len was particularly knowledgeable about film treatments for restoring damaged, shrunken or warped films and was very involved in the 'Film Clinic' which specialised in these techniques.
Len was an avid collector of technical journals and equipment related to the film industry, much of which he stored in his office over the course of his long laboratory career.
Len joined the BKSTS in 1951 and became a member of the Laboratory Committee in 1979.
As well as a distinguished career as a film laboratory technician Len was, in his spare time, a Special Constable in Central London and, when he was not working, Len enjoyed the freedom of the skies as a keen aerobatic pilot.
In the early 1990's Studio Film and Video Laboratories became Soho Images and when he retired from Soho Images Len set up a homeopathic practice from his home in which he has practiced for many subsequent years.
