The Manhattan Project

University Involvement in the Manhattan Project

Cambridge, MA

Harvard University

Harvard became an important center for nuclear physics research during the early twentieth century. After Ernest O. Lawrence constructed the first cyclotron at the University of California at Berkeley in 1929, Harvard physicists and engineers such as Harry Mimno, Kenneth Bainbridge, and Edward Purcell began thinking about building their own cylcotron. In 1936, the construction of the cyclotron began in the Gordon McKay laboratory, a wooden World War I building on the east side of Oxford Street. The magnet in the cyclotron weighed eighty-five tons.

Princeton University

Princeton University was a hotbed for nuclear physics research during the early twentieth century. Much of the research conducted at Princeton allowed scientists to develop and pursue a path to building the world's first atomic device. In fact, more than two dozen Princetonians were among the core group of brains at Los Alamos, N.M.

Jay Wechsler's Interview

Jay Wechsler: Well, my mother was visiting her folks in New York when she decided that it was time, and I was the first child, and I guess she was a little surprised. So I was born in New York even though we didn’t live there. And as soon as we were able we were back in New Jersey, where she and my father lived. My father was a chemist and even at a young age he was always taking me into the plant where he worked, showing me things. And I kind of had a mechanical bend or bent.

George Cowan's Interview (2006)

George Cowan: It's weighted so heavily in favor—not in favor of—but the emphasis on number one Los Alamos, and then Oak Ridge, and then Hanford, as the three secret cities or something. But the fact is the Met Lab at Chicago was enormously important. The Stagg Field reactor was historic in ’42, and its sort of dismissed. 

Donald Trauger's Interview

Donald Trauger: Yes, I’m Donald Trauger. And Trauger is T-R-A-U-G-E-R, Trauger. My mother-in-law when we first married would say auger, Trauger so she could remember it. [Laughter.]

Kelly: All right. Well, tell us how you came to Oak Ridge and how—what you did as your role in the Manhattan Project; where you were from and how you got involved.

Columbia University

Important Manhattan Project research was conducted at Columbia University’s Pupin Hall (right) and Schermerhorn Hall. World-class physicists, including Nobel Prize winners Isidor I. Rabi and Enrico Fermi, joined Columbia’s research team to investigate the relatively new science of atomic particles. Hungarian physicist Leo Szilard first realized the possibility of a nuclear chain reaction in 1933, and against the backdrop of escalating hostilties in Europe, the race began to harness the enormous energy within the atom.

Nash Garage Building

Located at 3280 Broadway, the Nash Garage Building was originally an automobile dealership which was purchased by Columbia University and converted into a pilot plant to create the barrier material for Oak Ridge, TN’s K-25 gaseous diffusion plant.

University of California-Berkeley

The "Rad Lab" was the short name for the Radiological Laboratory at the University of California, Berkeley. Its director was Nobel laureate Ernest O. Lawrence. He gained recognition for his 60" cyclotron,  a type of particle accelerator first invented in the early 1930s. Known as “atom smashers,” cyclotrons accelerate atoms through a vaccuum and use electromagnets to induce collisions at speeds up to 25,000 miles per second.

Robert Ellingson's Interview

Robert Ellingson: My name is Robert Ellingson, and it’s spelled E-L-L-I-N-G-S-O-N. 

Kelly: Great. Now if you could just tell us where you’re from, and how you happened to end up in the Manhattan Project.

Ellingson: I am from a little town in Idaho, and Idaho is west of Wyoming if you’re not familiar with the geography of the country. Most people look quizzical and say, “Iowa, that’s north of here, isn’t it?” But this is the one in the West.
