Alfred Tissiéres - The Double Helix

Sometime Jim was very difficult and people were old fashioned and they were thinking, I'm sure they were thinking, "Who is this young fellow who's criticizing me and being so disagreeable?" I think Bragg was one if those people. And finally somebody, I can't remember this very well, somebody [Max Perutz] said to Bragg that Jim was a good person and Bragg started listening to him.

On a whole Jim was really a-well, I used to see him every day-and I think he was a very good person. He wrote well. He was preparing to be a good scientist.
