Life

Emil-Joachim Birr was the son of the architect Emil Birr and his wife Marie, née Schmidt.

After graduating from high school in his hometown in February 1922, he studied chemistry at the University of Rostock , where he took the first part of the association examination with Paul Walden in March 1924 , the organic examination with Richard Stoermer in 1925 (March 1925), the examination on inorganic and physical chemistry (June 1925) and passed the association examination with Walden. In 1927 he received his doctorate in Rostock. He was a scientific assistant there until 1933 and then moved to the technical and scientific laboratory of the Wolfen film factory , where he was laboratory manager from 1935 to 1960. In 1951 he was honored with the title " Hero of Labor ".

Birr developed photographic stabilizers to improve the durability of the film materials without loss of sensitivity. Birr also processed photographic components such as hardeners, desensitizers, developer substances, gelatine ripening bodies and antistatic substances.

He left the GDR in 1960 and worked until 1969 as a research assistant and consultant in the Ferrania film factory in northern Italy. From 1970 he lived in Freiburg im Breisgau.
