Biography
Quastel, also known as "Harry" or "Q," was born at Ecclesall Road in Sheffield the son of Jonas Quastel, a confectioner, and his wife, Flora Itcovitz. His parents had come to Britain in 1897 from Tarnopol in Galicia (Eastern Europe) and were married in Britain. He was named after his grandfather,
Juda Quastel, a chemist in Tarnapol.
He was educated at Sheffield Central Secondary School. In the First World War, he served with the British Army as a Laboratory Assistant at St George's Hospital from 1917 to 1919.
Electing to study chemistry, Quastel received a baccalaureate from Imperial College London in 1921. Pursuing graduate work at the University of Cambridge, Quastel studied with Frederick Gowland Hopkins, the leading figure in British biochemistry and a future Nobel Prize recipient for his work on the nutritional importance of vitamins. Under Hopkins, Quastel received a Doctor of Philosophy degree from the University of Cambridge in biochemistry in 1924 and, not long after, was made a Fellow of Trinity College, Cambridge.
Quastel remained in Hopkins’ department as a demonstrator and lecturer from 1923 to 1929, during which he pioneered the research of microbial enzymology.
