The Kathleen Lonsdale paragraph has one small error. Kathleen was on the board of governors of the high school I attended (a Quaker school and she was a prominent Quaker). She gave the school a few tickets for the lucky ones to attend the annual Christmas lectures at the Royal Institution for high school students. That year they were given by the astronomer Royal. But it was in this way that I got to know Kathleen who took us around the basement of the Royal Institution where Michael Faraday used to work. Later I turned to her for help to find a research lab. That's when I started reading the book by Bunn. I heard Kathleen lecture a number of times while I was a student in London. It was difficult for students to follow her lectures. In contrast Sir Lawrence Bragg was terrific, and an example for me even to-day. To read Michael's oral history go to http://medicine.wustl.edu/~virology/rossmann.htm
