The Temmler Werke GmbH was founded in Detmold in 1917 by commercial counsellor Hermann Temmler. The establishment of a subsidiary in Berlin followed shortly after. Preparations for the treatment and alleviation of respiratory diseases became the hallmark of Temmler Pharma.
As of 1933, the company, with expanded production facilities, concentrated its business activities exclusively around the Berlin area.
In 1945 the facility in East Berlin was occupied and disassembled. The company had to be completely reassembled in Hamburg.
In 1960 the whole company transferred from Hamburg to Marburg.
