Harris Mayer's Interview

Nathaniel Weisenberg: My name is Nate Weisenberg. I’m here with Harris Mayer in Los Alamos, New Mexico. It’s October 11, 2017. My first question: if you could just say your name for the camera and spell it, please.

Harris Mayer: My name is Harris Mayer, H-a-r-r-i-s M-a-y-e-r.

Weisenberg: Thank you. I know you had a story that you wanted to begin with, so I will let you go ahead.

Martin Mandelberg's Interview

Cindy Kelly: I’m Cindy Kelly. It is Friday March 16, 2018. I’m in Washington, DC, and I have with me Martin Mandelberg. My first question for him is to please tell us your name and spell it.

Martin Mandelberg: Absolutely. My name is Martin Mandelberg. M-A-R-T-I-N. M-AN-D-E-L-B-E-R-G.

Kelly: That’s perfect. We would like to know, in a snapshot, an overview of who you are: when you born and where, and your education and career.

Martin Mandelberg

Dr. Martin Mandelberg is an engineer who is writing a biography on his doctoral advisor, Manhattan Project mathematician Richard Hamming. In this interview, Mandelberg discusses his work at General Dynamics, the Naval Underwater Sound Lab, SAIC, the Defense Department, and other jobs. He provides an overview of Hamming’s life and career, highlighting Hamming’s many important contributions to computing at Los Alamos and Bell Labs, and Hamming’s passion for solving big problems. Mandelberg also praises Hamming’s mentorship of his graduate students.

D.M. Ellett

D. M. Ellett is a mechanical engineer who joined the Manhattan Project after the end of World War II. He was a member of Z Division, which was assigned to Sandia Base in Albuquerque, New Mexico in 1945.

Stanley Hall's Interview

Cindy Kelly: I’m Cindy Kelly, Atomic Heritage Foundation, and we are in Los Alamos, New Mexico. It’s February 2, 2017. I have with me W. Stanley Hall. 

Hall: I was born in 1924 on Broadway in Manhattan. I was there until the third grade. In the fourth grade, I went to the Bronx and was there one year, and then went to Princeton, New Jersey, and stayed there until graduation from Princeton High School. Actually, we lived in Lawrenceville, New Jersey. Across the street was Princeton, but I went to Princeton High School.

Louis Hempelmann's Interview - Part 3

Martin Sherwin: What was the set-up at Los Alamos, in terms of your relationship to the director [J. Robert Oppenheimer] and how you operated?

Louis Hempelmann:  I was working directly under him. I started out with my wife as a half-time secretary, and the technician I brought with me from St. Louis, and Kitty worked for me.

Sherwin: What did Kitty do for you?

Hempelmann: Did blood counts.

Sherwin: Was she a good technician?

Edwin McMillan's Lecture

Edwin McMillan: Ladies and gentlemen, I would like to start with two remarks. First, this is going to be a personal story, so if I use the first person singular, this is not pure egotism, it is simply the fact that that’s the part that I know best. Second remark is, the difficulty of establishing facts at such a late date, even of important things. During the Manhattan Project, of course, there was security impressed upon everyone, so very few people kept any notes.
