Gertrude Elion saw her grandfather die of cancer when she was 15 years old, and this was the ‘turning point’ in her life which made her decide to study science in order to search for a cure for cancer.

Gerty Theresa Cori was an American biochemist that studied animal metabolisms and the conversion of glycogen into glucose. Her work earned her a Nobel Prize in 1947 when she became the third woman ever to do so.

Through his observations of the natural world in his country parish, the Reverend Gilbert White transformed the way we look at the natural world and is known as one of the fathers of ecology. In his journals, his painstaking observations provided many important insights into the natural world around him.  For example, he was the first person to accurately describe the harvest mouse and noctule bat. He was an inspiration to many other naturalists. 

Gregor Mendel established the laws of inheritance which to this day underpin the field of genetics.

Gregory Pincus was an American endocrinologist and authority in mammalian reproduction. He is most famous for the invention of the oral contraceptive pill and is credited with revolutionising family planning.

Hans Christian Gram was a Danish pharmacologist and pathologist who developed a system of easily identifying between two main types of bacteria. The method, Gram staining, is still widely used and in many cases an invaluable tool in laboratories.

Sir Hans Kornberg is an esteemed biochemist with a broad academic history spanning across top universities in the UK and the USA. His research area asks questions about how micro-organisms use and transport small molecules called carbohydrates.

Hans Kosterlitz was a German-born British pharmacologist who discovered enkephalins, the body's natural painkillers that occur in the brain.

Sir Hans Adolf Krebs was a physicist and biochemist who is most renowned for his discoveries concerning cellular respiration, a biochemical pathway in cells that enables the production of energy. He discovered  two important chemical reactions in the body; the urea cycle and the citric acid cycle.

Sir Hans Sloane was a physician and botanist whose personal collections led to the establishment of the British Museum (and later the Natural History Museum). He also promoted inoculation against small pox and the use of quinine for malaria.
