During 1935, German composer Paul Hindemith and theatre director Carl Ebert were invited to give lectures at Musiki Muallim Mektebi in Ankara, which was subsequently transformed into Ankara State Conservatory. The two lecturers were offered permanent posts at the conservatory, an offer which Paul Hindemith was not able to accept. Nevertheless, he kept visiting Ankara and inspecting the activities at the music school. Carl Ebert stayed in Ankara as the director of the conservatory theatre school and opera studio for the following nine years.
