About the Weinberg surname. The Weinberg name appears among Jews of East Europe in various locations. It is from the German word for vineyard. In the 18th and 19th century, government clerks began assigning family names to Jews ( and others), often based on occupation, location, or prestige.
Weinberg, professor emeritus of history at the University of North Carolina at Chapel Hill and the author of several seminal military history books, including A World at Arms (1995) and Visions of Victory (2005), won the 2009 Pritzker Military Library Literature Award for Lifetime Achievement.
