Howard Walter Florey

Howard Walter Florey was born on the 24^th of September 1898 in Adelaide, South Australia. His father, Joseph, emigrated to Australia in 1882 with his first wife Charlotte Ames, and their two daughters. After the death of his first wife in 1886, Joseph married Bertha Mary Waldham, and together they had three children: Hilda (1890), Valetta (1891) and Howard (1898). [1]

Florey attended Unley Park School, Kyre College Preparatory School (now Scotch College) and St Peter’s Collegiate School, excelling in chemistry, physics, and mathematics. [2] Despite his recurring respiratory issues during his youth, he remained an outstanding student, ranking 12^th overall in the Higher Public Examination Honour List in 1916. [3] Rejecting following in his father’s footsteps as a boot manufacturer, and inspired by his older sisters’ medical careers, Florey pursued medicine at the University of Adelaide, graduating in 1921 with a Bachelor of Medicine and a Bachelor of Surgery (M.B. B.S.). During his studies, he met Mary Ethel Hayter Reed (1900-1966) who was also studying a M.B. B.S. and they married on the 19 October 1926 having two children, Charles du Ve and Paquita.

As a Rhodes Scholar Florey sailed to England in 1922 and studied in the honour school of physiology at the University of Oxford, and in 1924 was awarded a Bachelor of Science and Master of Arts. [4] Howard transferred to the University of Cambridge where he studied for his PhD and lectured in pathology from 1927. [5] His academic journey included scholarships and fellowships across Europe and the Unted States.

In 1931, Florey was appointed Professor of Pathology at the University of Sheffield and in 1935 returned to the University of Oxford as Head of the Sir William Dunn School of Pathology. There, he, Ernst Chain and Norman Heatley, developed methods to purify and mass-produce penicillin, a breakthrough that revolutionised medicine and saved countless lives during the Second World War.

His contributions in medicine earned him a knighthood in 1944 and the Nobel Prize for Physiology and Medicine in 1945, alongside Chain and Alexander Fleming. [5] A peerage was bestowed on Howard in 1965, making him Baron Florey of Adelaide and Marston. [6]

Florey passed away on the 21 February 1968 at Oxford, leaving behind a legacy as one of the most influential scientists who helped change the course of modern medicine. [7]
