Ronald Hare was born in 1899. He served in the 2/25th London Bn. He served in France in 1918, as far as I can ascertain it most most likely that he was attached the the 10th London Bn. He wrote a diary of his time in the war, albeit a short time, in which he was wounded.

Ronald Hare trained a as Doctor and became involved in medical research. It was Hare as Professor Fleming's assistant who made an extraordinary discovery. Although Alexander Fleming discovered penicillin in 1928, he didn't know why it worked. It was Hare who was able to point out that the penicillin had worked only because of an unusual change of temperature at that time of year. Referring to the London Meteorological Records for that fortnight in July 1929, Ronald Hare discovered that there had been a nine day period of unusual cooler temperatures. This favoured the growth of the Penicillium mould. Penicillium grows at 25 C. The Staphylococcus at 35C. All over Europe, laboratories had tried to replicate Fleming's discovery but could not make penicillin work. Ronald Hare's work showed how.

In 1936 Professor Hare was appointed Research Associate at the University of Toronto and later was largely responsible for the planning and building of the Penicillin Production unit set up by the Canadian Government.
