Otto Perutz (born 1847 in Teplice, died 1922 in München) was a chemist who had finished his studies in Zurich with a degree dissertation about a photo-chemical topic and became manager of a factory for chemicals. In 1880 he founded his own enterprise, a factory for making dry plates. This became the Perutz-Photowerke. The company was bought in 1964 by concurrent Agfa. Then the brand Perutz which had become famous for color slide film was kept alive for a while.
