Mr. Capp was assigned to the occupation forces outside Hiroshima after World War II. According to to Mr. Capp’s oral history (available along with the photographs in the Robert L. Capp collection), he found these photos among rolls of undeveloped film in a cave outside of Hiroshima. Since making these photographs publicly available, I have received reliable proof that at least two of these photos are actually of the 1923 Kanto earthquake. While I cannot speak for the entire collection, this evidence raises doubts about all of the photos and raises the strong possibility that the identification provided by the Hoover Archives is incorrect. I take full responsibility for my own failure to take additional steps to verify that the original archival designation was correct. I have removed the photographs until and unless their source can be verified by further research.
