Julius Richard Petri was a German microbiologist, born in Barmen, now part of Wuppertal, on 31 May 1852 and died on 20 December 1921. He studied medicine at the Kaiser Wilhelm Academy for Military Physicians, received his medical degree in 1876 and served as a military physician until 1882. From 1877 to 1879 he was assigned to the Imperial Health Office in Berlin as an assistant to the bacteriologist Robert Koch. There, after Koch's laboratory began culturing bacteria on agar plates, Petri invented the standard culture dish, known as the Petri dish or Petri plate, and developed the technique of agar culture to purify bacterial colonies derived from single cells. This advance made it possible to identify rigorously the bacteria responsible for diseases.
