Mostly science, yeah, about the work he was doing and what other people were doing and so on. He did a lot of that. You know, I really got a lot out of him. I don’t think he talked to ___nearly as much as he did to me. So, I think that probably was the thing that he gave me that was the greatest for me. It was worth no amount of money or anything else. I mean he didn’t support me in college. I had the GI Bill and didn’t do anything like that, but he gave me much more by his giving me this kind of talk. This kind of bringing up and so on. So I always felt that that was exceedingly valuable to me.

David E. Muller was born in 1924 in Austin, Texas. He is the son of Hermann J. Muller, who received a Nobel Prize in 1946 for his discovery of x-ray induced mutations in Drosophila melanogaster, and Jesse Jacobs Muller Offermann, a mathematician and first wife of H.J. Muller.

In the 1930’s, H.J. Muller left his laboratory at the University of Texas to work at the Kaiser Wilhelm Institute in Berlin. He then moved to Russia where he joined the Institute of Genetics and later the Institute of Animal Genetics in Edinburgh. During this time, David and his mother traveled to Germany and Russia to visit his father. After H.J. Muller’s return to the United States in 1940, David reunited with his father at the 1941 Cold Spring Harbor Laboratory Symposium for Quantitative Biology. Afterward, David returned to school at Caltech and H.J. Muller to his appointments at Amherst College (1940-1945) and Indiana University (1945-1967).

Following in his mother’s footsteps, David became a mathematician and began working with computers at the University of Illinois in 1952. There he designed the Muller C-element, which is a commonly used component in computers. He taught at the University of Illinois until 1992 at which time he retired.

In April 2005, David donated his collection of photographs and personal letters written primarily by his parents and Carlos Offermann (one of H.J. Muller’s top graduate students and David’s step-father) to the Cold Spring Harbor Laboratory Archives. The letters were written between 1900 and 1945, although the bulk of the letters date from the early 1920’s when H.J. Muller took his first trip to Europe and the 1930’s when H.J. Muller was working in Germany, Russia, and the UK. These letters also cover the period of time when H.J. Muller made his Nobel-winning discoveries.
