Gerhard Ludwig Weinberg (born 1 January 1928) is a German-born American diplomatic and military historian noted for his studies in the history of Nazi Germany and World War II. Weinberg is the William Rand Kenan, Jr. Professor Emeritus of History at the University of North Carolina at Chapel Hill. He has been a member of the history faculty at UNC-Chapel Hill since 1974. Previously he served on the faculties of the University of Michigan (1959–1974) and the University of Kentucky (1957–1959). Weinberg was born in Hanover, Germany, and resided there the first ten years of his life. As Jews living in Nazi Germany, he and his family suffered increasing persecution. They emigrated in 1938, first to the United Kingdom and then in 1941 to New York State. Weinberg became a U.S. citizen, served in the U.S. Army during its Occupation of Japan in 1946–1947, and returned to receive a BA in social studies from the State University of New York at Albany. He received his MA (1949) and PhD (1951) in history from the University of Chicago. Weinberg recounted some of his childhood memories and experiences in a two-hour long oral history interview for the United States Holocaust Memorial Museum. Weinberg has studied the foreign policy of National Socialist Germany and the Second World War for his entire professional life. His doctoral dissertation (1951), directed by Hans Rothfels, was "German Relations with Russia, 1939–1941," subsequently published in 1954 as Germany and the Soviet Union, 1939–1941. From 1951 to 1954 Weinberg was a Research Analyst for the War Documentation Project at Columbia University and was Director of the American Historical Association Project for Microfilming Captured German Documents in 1956–1957. After joining the project to microfilm captured records at Alexandria, Virginia, in the 1950s, Weinberg published the Guide to Captured German Documents (1952). In 1958, Weinberg made the discovery of Hitler’s so-called Zweites Buch (Second Book), an unpublished sequel to Mein Kampf, among captured German files.
