[3] In 1929 he was chief conductor (Erster Kapellmeister) at the theater (Stadttheater) in Ulm when Herbert von Karajan was appointed there as his junior colleague.
When this job came to an end he no longer had any position so he traveled to Milan to embark with his wife Sophie for America.
[6] Schulmann settled down in San Francisco and taught voice; his wife Sophie first worked as a chef to save money for opening a restaurant.
[12][13] Another student of Schulmann was the mezzosoprano and soprano Janis Martin, a famous international Wagner performer as well.
[16] From 1958 to 1968 Schulmann taught at the San Francisco Conservatory of Music,[17] where one of his students was the tenor Ronald Moreno Gallegos.
