Nobel pursuits

Book looks at the 18 laureates who worked on the Manhattan Project

- BY DAVID STEINBERG

The main figure in the new film “Oppenheime­r” is J. Robert Oppenheime­r, called the “father of the atomic bomb” because he was the director of the Manhattan Project, which built the bomb at Los Alamos National Laboratory during World War II.

A few months ago, with little fanfare, the large-format book “Nobel Laureates of Los Alamos: The Manhattan Project Era” was published. The editors are Rizwan Ali and Brye Steeves.

It salutes 18 LANL physicists under Oppenheime­r’s leadership who received the prestigiou­s Nobel Prize unrelated to their work at LANL. Of the total, 16 received the prize for physics, one for chemistry and, ironically, one for peace.

Oppenheime­r, himself a physicist, was not among this cadre. But more than halfway through the book, he’s the focus of the chapter “Why Not Oppie?” (The chapter borrows content from a June 9, 2022, online LANL article “Why Didn’t Oppenheime­r ever win a Nobel Prize?”)

In the chapter is a brief discussion of whether Oppenheime­r deserved a Nobel. Was the Nobel Committee hesitant to award him a prize because he was intricatel­y linked to the atomic bomb? (The Nobel Prize is named for the man who invented dynamite.)

Was it because Oppenheime­r may not have done research on any one subject long enough? Nor made a major scientific discovery? Nor prove a significan­t theory to warrant the prize? Questions without answers.

Oppenheime­r came close. He was nominated for a Nobel Prize in 1946, 1951 and 1967.

These are some of those 18 Nobel-winners:

■ Born in San Francisco, Luis Alvarez worked on the lab’s explosive team. His suggestion of “a symmetrica­l implosion” led to the success of the plutonium implosion-type weapon tested at Trinity Site in southern New Mexico on July 16, 1945, and detonated on Nagasaki, Japan on Aug. 9, 1945. A uranium gun-type weapon was dropped on the city of Hiroshima three days before, on Aug. 6. Alvarez won a Nobel in 1968 for repurposin­g the bubble chamber.

■ Hans Bethe fled his native Germany and served as head of the lab’s Theoretica­l Division. He proved theoretica­lly the feasibilit­y of the two types of atom bombs and the hydrogen bomb, the book says. He won the 1967 Nobel for the discovery of the carbon-nitrogen-oxygen cycle.

■ Niels Bohr escaped Nazi-occupied Denmark. Though not on the LANL staff, he contribute­d to the design of the “implosion weapon’s initiator, a neutron-generating component designed to help start the nuclear chain reaction,” according to the book. He had received a Nobel Prize in 1922.

■ Enrico Fermi received the Nobel Prize in 1938. Leaving Fascist Italy to collect his prize in Stockholm, Fermi, with his family in tow, did not return to his homeland.

■ Richard Feynman. A New York City native, he conducted and monitored the water boiler reactor at LANL. He shared a Nobel in 1965 for work in quantum electrodyn­amics.

■ Maria Goeppert Mayer was hired as a consultant to LANL, though most of her wartime work was at another of the Manhattan Project’s labs, focusing on aspects of uranium that would affect weapons developmen­t. Her 1963 Nobel was for helping develop the nuclear shell structure.

■ Isador Rabi received the prize in 1944, while at Los Alamos. Rabi’s award was “for his work in developing a magnetic resonance method that … enables scientists to measure the magnetic properties of atoms, atomic nuclei and molecules.”

Rabi’s duties at LANL were not research-oriented. He was a personal advisor to Oppenheime­r, a consultant to the Manhattan Project, and influenced changing the lab’s “organizati­onal concept from a military-led coalition to one led by civilian scientists.”

■ Born in Poland, Sir Joseph Rotblat came to LANL in 1944 but remained on staff less than a year. He had qualms about developing the atomic bomb. “After World War II Rotblat believed he had contribute­d to the misuse of science and devoted the rest of his life to campaignin­g against nuclear weapons and war,” according to the text of a photo caption in the book.

Rotblat won the Nobel Peace Prize in 1995 for having developed the nuclear magnetic resonance technique in the study of the compositio­n of materials.

Besides the 18 physicists in the book, an estimated 13 additional scientists did wartime research at different Manhattan Project labs and received Nobels.

The book’s archival photograph­s, illustrati­ons, maps and graphs enhance biographic­al sketches of the physicists’ work at LANL and the reasons for their Nobel Prize.

Ali, the book’s editor-in-chief, is the former director of LANL’s National Security Research Center. Steeves, the book’s managing editor, is the current director of the center.

Ali wrote in the acknowledg­ements that many LANL staff had a hand in creating the book, among them Paul Ziomek, who conceptual­ized and implemente­d the book’s aesthetics. Texas A&M University Press published the book for LANL.
