content: The Zeiss Optical Co. in Jena developed this type of prism binoculars in the 1890s. This example, made by Bausch & Lomb for the U.S. Army Signal Corps, was issued to Leigh Patterson Jerrard, an artillery officer with the 42nd (Rainbow) Division. Jerrard was sent to France to observe German positions and possible targets during World War I. He took the binoculars home in 1918. At the time of World War II, he lent them to the War Department for use by the Navy Bureau of Ships. The binoculars were then returned to Jerrard, and his son donated them to the Museum. The binoculars are marked: "BAUSCH & LOMB OPTICAL CO. ROCHESTER, N.Y." and "U.S. NAVY" and "No. 1533-1942" and "BU. SHIPS” and L.P. JERRARD."
