The Galerie Heinemann was founded in 1872 by David Heinemann (1819-1902) and was numbered amongst the most important art dealerships in Germany until its "Aryanization" in 1938. In Munich its rooms were originally located at Promenadeplatz, later they were moved to the Prinzregentenstraße and as of 1902 to Lenbachplatz 5/6. The gallery, which operates internationally, had several branch offices in cities such as Frankfurt am Main, Nice and New York. It specialized in 19th and early 20th century German art, but also dedicated itself to English, French and Spanish art. Altogether it organized approximately 300 solo and thematic group exhibitions between 1880 and 1935.
