I thought I should say something special about Luis Alvarez because he was an extraordinary scientist at this time. He joined the Laboratory in 1936.

Here's a picture of him with a neutron counter taken in 1938. He is responsible for a large number of discoveries.Here is a note from my journal of April 15, 1938. I've kept a journal since January 1, 1927. Here is my description of a paper I had just read in which he discovered decay by electron capture. He is the discoverer of that method of decay. Here is a picture taken in 1938 of Luis Alvarez with Robert Oppenheimer, Willie Fowler of Cal Tech, and Bob Serber of the Radiation Lab at that time.

|Radioistopes discovered at LBL commonly used in nuclear medicine|
Here's a number of radioisotopes discovered at Lawrence Berkeley Laboratory commonly used in nuclear medicine. I won't stop there, but I was involved in the discovery of a number of these. In fact the isotopes that I was involved in the discovery of, used in nuclear medicine, are used some 10 million times a year now in the diagnosis and treatment of disease. In fact, one of them saved my mother's life, iodine-131. She had a fatal hyperthyroid condition and she was diagnosed and treated with iodine-131 as were George Bush and Barbara Bush who, as you know, are suffering from Graves' disease.
