Theodor Marcus founded the Academia Verlag in Prague in 1936; he was manager until 1940, although he had ceased his publishing activities on March 15, 1939.
In the 1920s, Marcus had been a co-partner in the publishing house M. & H. Marcus. Starting in 1934, his business suffered from anti-Semitic backlashes; he tried to transfer the publishing house to Switzerland, but his attempt failed. He was denaturalized and subsequently fled to Czechoslovakia.
