The German-American Heritage Museum opened in 2010, in Hockemeyer Hall at 719 6th St. NW. Hockemeyer Hall was built in 1889 by the prominent German-American John Hockemeyer. Hockemeyer emigrated to the U.S. at age 15, and served in the Civil War, and later became a prosperous food merchant. His residence became a social center for the surrounding German community. It is believed that the house contained one of the first bowling alleys in D.C.
