After the war, the Navy had no further use for U-505. She had been thoroughly examined in Bermuda, and was now moored derelict at the Portsmouth Navy Yard. It was decided to use her as a target for gunnery and torpedo practice until she sank.[23] In 1946, Gallery, now a rear admiral, told his brother Father John Gallery about this plan. Father John contacted President Lenox Lohr of Chicago's Museum of Science and Industry (MSI) to see if they would be interested in U-505. MSI, established by Chicago businessman Julius Rosenwald, was a center for "industrial enlightenment" and public science education, specializing in interactive exhibits. As the museum already planned to display a submarine, the acquisition of U-505 seemed ideal. In September 1954, U-505 was donated to Chicago by the U.S. government, a public subscription among Chicago residents raised $250,000 for transporting and installing the boat. The vessel was towed by United States Coast Guard tugs and cutters through the Great Lakes, making a stop in Detroit, Michigan in the summer of 1954. On 25 September 1954, U-505 was dedicated as a permanent exhibit and a war memorial to all the sailors who lost their lives in the two Battles of the Atlantic.
