Bernard Waldman (October 12, 1913 – November 1, 1986) was an American physicist who flew on the Hiroshima atomic bombing mission as a cameraman during World War II.

He headed a group that conducted blast measurements for the Trinity nuclear test, and served on Tinian with Project Alberta.

[1] His thesis, on "The Resonance Processes in the Disintegration of Boron by Protons",[2] formed the basis of a paper published in the Physical Review.

[4] He took a leave of absence from Notre Dame and joined Oppenheimer and Serber at the Manhattan Project's Los Alamos Laboratory in 1943.

He was equipped with a special high-speed Fastax movie camera with six seconds of film in order to record the blast.

Sources vary on how it came to be that there is no film of the event, with theories stating that Waldman forgot to take the lens off of the camera or that the footage was unusable or destroyed due to circumstances outside of his control.

[1] A funeral service was held at the Basilica of the Sacred Heart on the campus of the University of Notre Dame, and he was interred in its Cedar Grove Cemetery.
