Martin Dülfer (1 January 1859 in Breslau – 21 December 1942 in Dresden) was a German architect and professor; best known for designing theatres in the Historical and Art-Nouveau styles.
Then, from 1877 to 1879, he studied at the Polytechnic School in Hannover, with Conrad Wilhelm Hase and, from 1879 to 1880, at the Technischen Hochschule in Stuttgart with Christian Friedrich von Leins.
Following a brief period of military service, he took a position at the Berlin offices of Heinrich Joseph Kayser [de] and Karl von Großheim.
He became a professor emeritus in 1929 and disappeared from public notice until 1939, when he was given the Goethe-Medaille für Kunst und Wissenschaft, despite the fact that he was a Freemason and therefore considered to be an "unreliable" person under Nazi cultural policy.
Käte was killed during the bombing of Dresden, at which time their home and estate, as well as his grave at the Alter Annenfriedhof [de], were also destroyed.
