In 1920, the first branch of I.B. Neumann's art gallery in Berlin, the Graphische Kabinett, was founded in Bremen on Fedelhören 11. In 1922, it was taken over by Lina Voigt, R.A. Schröder's sister and A.W. Heymel's cousin. In 1925, her son Peter joined the company and moved the gallery to Rembertistrasse 1A. From 1950, after Peter Voigt passed away, Ursula Voigt managed the gallery. In 1970, on the gallery's 50th anniversary, Wolfgang Werner took the gallery over. In 1991, a branch was opened in Berlin on Fasanenstrasse 72.
