I had the good luck to meet interesting people in my job... interesting interviews. The Americans did a series called Wisdom Series — NBC — which first I filmed Sean O’Casey. They brought over Barry Fitzgerald who was the first Joxer in The Plough and the Stars. And they hadn’t seen each other for 20 years, and embraced. And it was so moving seeing... how pleased they were to see each other after all this time. And that is how I got to know Sean O’Casey. I had other... another opportunity. Rotha made a film about the Abbey Theatre in Dublin. We filmed it in the ruined Dublin theatre, because it had burnt down at one time, and a new one was being built opposite almost. Anyway, O’Casey was very nice, and his wife was very nice. We got to know each other very well, and his children. He had three children. Lost one unfortunately through leukaemia, which broke his heart. And Eileen O’Casey was a very good hostess, looked after us, and I kept up the friendship, went to photograph him several times. There’s a nice picture of my daughter sitting on the lap of O’Casey, when she was about 12 maybe. Well, he was one... certainly one of the highlights of my career, to get to know him. In 1939 I was asked by a weekly journal, a rival to Picture Post, called Illustrated, to photograph... photograph H.G. Wells in his home overlooking Regent's Park. And he was very willing to be photographed, and very nice to us. I went with a journalist who then wrote the story in the journal. He even made a suggestion I should photograph his hands with the script, which I did. And we spent the whole morning in his house, and on his balcony, and on the street even. He was very obliging. Other important people I came across was Fleming the discovery... discoverer of penicillin, Alexander Fleming; he wasn’t a Sir yet. We made a film about penicillin, and the group of people who developed it made it possible that it was produced on a... a large scale. The people involved were Chain — Dr Chain — who was an outstanding chemist — and I think he shared the Nobel Prize — and the Oxford five people who analysed penicillin. And I was able to take a group of the five in the professor’s office, which is now in the National Portrait Gallery among other things I have taken.
