Robert Krohn of Los Lunas and Los Alamos passed away in May at the age of 94. Bob was born on December 26, 1919 in Milwaukee, Wis., to Hugh and Pauline Krohn. He attended the University of Wisconsin for both undergraduate and graduate degrees in physics.

Bob was offered a job at Los Alamos in 1943 to work on the Manhattan Project. He married Barbara Ann Rockwell, his college sweetheart, in 1943. He was one of the few scientists to witness the testing of the atomic bomb at Trinity Site on July 16, 1945. A decade later, Bob was the Task Commander for the explosion of the world’s first thermonuclear bomb on the Pacific Island of Eniwetok.

Bob organized and equipped Los Alamos Scientific Laboratory’s first museum that for many years was located in an unused ice house on the edge of Ashley Pond. Today the museum he created is known as the Bradbury Science Museum. Bob was active as a Boy Scout leader and was an umpire for Lassie League. Bob and Barbara were founding members of the American Belgian Tervuren Club, the Los Alamos Dog Obedience Club, and the United Belgian Shepherd Dog Club. He was a confirmation judge and obedience judge for American Kennel Club.
