Franz Ehrlich was a German architect, calligrapher and graphic designer. Franz Ehrlich was a student at the Bauhaus in Dessau from 1927 to 1930. During his Bauhaus period he worked together with Walter Gropius on the Total Theatre project of Erwin Piscator and became engaged in sculpture and typography. Until the summer semester of 1930, he was involved in the sculpture workshop with Joost Schmidt and passed his journeyman's examination as a carpenter at the Chamber of Crafts Dessau during the winter semester of 1929-1930. In the following year, he received his Bauhaus diploma from the sculpture workshop. Directly after receiving his concluding Bauhaus diploma in 1933, he followed Walter Gropius to Berlin. Together with the Bauhausler Heinz Loew and Fritz Winter, they opened the 'Studio Z' advertising office. In addition, he also intermittently worked at the studio of Naum Gabo.

Because of his Communist involvement - among other things, he was the graphic designer for the illegal Junge Garde (Young Guard) magazine starting in 1933 - he was arrested in Leipzig in 1934. During his time in prison in 1935, he created the series called Blatter aus der Haft (Sheets from Prison). Starting in 1937, the location of his imprisonment was changed to the Buchenwald concentration camp where his profession as an architect saved his life: He was forced to work and commissioned to design the interior decoration for the residence of the SS camp commander. He subsequently received further commissions from the SS, including the creation of the lettering 'To each his own' for the gate of the concentration camp.

After the end of the Second World War, Franz Ehrlich worked as an urban planner and architect in Dresden. Starting in 1950, he was the technical director of the Design Office for Industrial Construction of the GDR in Berlin. Among other things, he designed the first Leipzig trade fair after 1945. In 1955, Ehrlich became the architect of the GDR Ministry for Foreign Trade and designed the interior decoration for numerous GDR foreign embassies and trade missions. One of the architectural highlights of his career is the Broadcasting Centre Berlin in Kopenick, which he designed and built together with Gerhard Probst. Starting in 1956, the 602 furniture series was produced at the Deutsche Hellerau Werkstatten (German Workshops of Hellerau) according to his design.
