Julius Gollmann (1840-1898) was a German painter who worked in Cleveland around the Civil War era. A native of Hamburg, he was active in the United States by the early 1850s. He worked principally in New York City, where he often exhibited portraits at the National Academy of Design. In the late 1850s, however, he was a member of the small art colony of Cleveland. His most significant contribution to the city's cultural heritage was the commission he undertook in 1858 to paint "A Meeting at the Ark." William Case paid Gollmann $400 for the group portrait, which depicted 14 members of the early intellectual circle known as "Arkites" and which eventually became part of the collection of the Western Reserve Historical Society. After another sojourn in New York, Gollmann returned to Cleveland at least once again c. 1872 before going back to Germany. Much of his later career was spent in Berlin, where he exhibited at the Berlin Academy in 1878 and 1890 prior to his death in that capital.
