Erich Seer was a graphic designer and artist. He came from Neubrandenburg. His father, Johannes Richard Seer, was a dentist. Erich had an older brother, Max. Little is known about Erich Seer’s life. He married Berta Paula Seer (née Niebengall), but the marriage was dissolved in 1933 at the district court in Eisenach (Thuringia). As Erich Seer was in the Ellen institution (Bremen) between 1928 and 1938, the divorce was finalised without him. In November 1938, he was transferred from Ellen to the Lüneburg institution in a collective transport. It cannot be ruled out that his early dementia was triggered by »syphilis«. Until 1928, he worked as a graphic artist and painter. His best-known works are collages in which he combined the paper-cutting technique with various materials. On 7 March 1941, he was transferred to the Pirna-Sonnenstein killing centre and murdered with carbon monoxide.
