We just never know whom we’re going to find for our next guest post. Today, we’re featuring the granddaughter of Kenneth T. Bainbridge, the director of the Trinity nuclear test. This guest post is a great complement to our In the Footsteps series, which you can find HERE.

Claire Robinson May is a playwright in the Northeast Ohio Master of Fine Arts (NEOMFA) program. Her ten-minute performance piece, The Trinity Project, is being produced this month by the Oddy Theater Lab. Her full-length plays Mother/Tongue and Standardized ChildTM have been performed at Cleveland Public Theatre. She teaches Legal Writing at Cleveland-Marshall College of Law and lives in Cleveland Heights with her husband, two sons, and a few other animals.


“Now we are all sons of bitches.” That’s what my grandfather, Kenneth T. Bainbridge, said after the successful Trinity test of the first atomic bomb at Alamogordo, New Mexico, in July 1945. Not a grand soliloquy like J. Robert Oppenheimer’s—Ken cut right to the heart of the matter.

Ken Bainbridge directed the Trinity Test. He always said he was glad the test was a success because otherwise he would have had to climb the tower to investigate what had gone wrong.

Ken was forty at the time of the test and a married father of three. He was a Harvard University physics professor who had relocated his family to Los Alamos, New Mexico, so that he could work on the Manhattan Project, one of the most top-secret endeavors in history.

Ken and his nine-year-old son, Martin, drove from Cambridge to Los Alamos in early July 1943. In late August, after Ken had arranged for their housing, my grandmother, Margaret Bainbridge (Peg), brought daughters Margaret (Margi) and Joan out to Los Alamos on the train. Joan was six. My mother, Margi, was fourteen months old. She learned to walk on the train to New Mexico. They lived at Los Alamos for the next two years.

The Bainbridges moved into a two-family house on the coveted Bathtub Row (so named because the street had the only housing units with bathtubs). Physicist Norman Ramsey’s family lived on the other side of the house. (Ramsey would go on to share a Nobel Prize in 1989.) Joan and Martin explored the new landscape, distressing the patrol guards with their utter disregard of the security fence.

Oppenheimer managed the gasoline rations so that scientists and their families could take the occasional day trip. There were picnics, mineral collecting outings, and visits to the pueblo. Joan remembers weekend fishing trips and other adventures with her father, writing, “I have some childhood memories with Dad at Los Alamos—I still have the trout rod he made for me, hand wrapped with silk . . . but, thinking about it, there are not as many as I might have imagined. He was very absorbed and then gone much of the time in the spring of ’45.” The test blast would occur on July 16, 1945.

After the war, my grandfather joined the numerous physicists who spoke out against nuclear weapons. But he never wavered in the conviction that developing the bomb was necessary. He later wrote in the Bulletin of Atomic Scientists that he had “a somewhat bloodthirsty viewpoint on the war” when he decided to join the Manhattan Project because he’d already heard first-hand accounts of Nazi atrocities from some of the European scientists he knew.

When I studied the history of science as an undergraduate at Harvard University in the early 1990s, I invited my grandfather to come to campus to hear a panel discussion that took place each year in one of the core science courses. Scientists such as Hans Bethe and Victor Weisskopf spoke to students about the development of the bomb and the decision to use it against Japan to end the war. Ken’s Los Alamos friends would wave from the stage, delighted to spot him in the Science Center auditorium. I was always proud to be with him. It was hardly a coincidence that my undergraduate studies focused on the history of twentieth-century physics.

Ken Bainbridge didn’t want to be remembered only for the bomb. He had many other achievements, both before and after the war, including his work on the Harvard cyclotron and the first experimental verification of E=MC2. When he chaired the Harvard University physics department in the early 1950s, Ken staunchly defended colleagues against the blacklisting attacks of Senator Joseph McCarthy. My grandfather was widely respected in his field as a careful and conscientious experimentalist and as a mentor to younger physicists. He was beloved by his family and many friends.

My grandfather died in 1996, shortly before his 92nd  birthday. His wife, Peg, had died suddenly in 1967, several years before I was born. With both of them gone, I can’t help but wonder what transpired between my grandparents in the days after the test, when the families finally knew what really had been going on at Los Alamos. I wonder what role the experience may have played in Peg’s decision not long after the war to become a Quaker, a faith that wholly rejects violence. I now find myself drawn to the point where human history and family history intersect, in a blinding desert sky.

  1. This really is close to home for me. I live in Las Cruces, NM. The Trinity sight was just opened to the public on the first Saturday of April and will be open again to the public on October 6. I have not been there, but friends just did the April tour and memorabilia display and said it is fabulous. If I am still on this side of the grass (or desert sand) next April, I plan on going.
