Australian pharmacologist and pathologist who distributed the Nobel Prize in Physiology or Medication in 1945 for his role in the making of penicillin. His breakthrough was approximated to have kept over 82 million lives. He received a PhD in the School of Cambridge. He could generate penicillin after he uncovered it unintentionally in 1928 as mould in his petri dish, which he still left unwashed throughout a holiday. He wedded his long-time colleague and analysis helper Dr. Margaret Jennings in 1967 after his initial wife Ethel passed on. He distributed the 1945 Nobel Award with Alexander Fleming.
