I shot this portrait of Carl Djerassi, co-inventor of the contraceptive pill, scientist and playwright in his London flat. He was mainly resident in San Francisco but kept a home in the UK as well. He was a very quiet and considered man who was used to, but not particularly keen on, publicity. I was attracted to the shape of his dining chairs and the almost egg-like shape of the top. I don’t recall whether we discussed the shape at the time!
