J. Robert Oppenheimer's House

Two people stand in dappled shade under a tree and in front of a single-story historic wooden house that once housed J. Robert Oppenheimer and his family during the Manhattan Project.

Visitors to Los Alamos can walk among the houses of key Manhattan Project people such as that of J. Robert Oppenheimer. Although closed to entry, visitors can still look into doors and windows to see rooms set up as they were during the Manhattan Project. Manhattan Project Scientific Director Dr. J. Robert Oppenheimer, his wife Kitty, daughter Toni, and son Peter lived in this home from 1943-1945. Built in 1929, the Oppenheimer house served the Los Alamos Ranch School before the Manhattan Project took over. School director A.J. Connell’s sister May lived in the house in the Ranch School days, moving to New Mexico from New York. Adamant that she would not live in a “log cabin,” the school hired a local stonemason to build the house. In June 1942, when Gen. Leslie Groves appointed Dr. Oppenheimer scientific director of the weapons development laboratory, the commander of the Manhattan Project had yet to choose a location for the secret laboratory. Oppenheimer, familiar with the Santa Fe area, played an instrumental role in the selection of Los Alamos.
