Following the fascinating Historical Vignette "The History of Endoscopy"1 that includes an interview with Karl Storz, I would like to add some details about Harold Hopkins, the inventor of the rod lens endoscope.
Hopkins was born in 1918 in Leicester, England, the youngest son of a baker. He went to school and university in Leicester. He graduated with emphases in mathematics and physics in 1939. Jobs were scarce, the first available being with a lens maker in Leicester called Taylor, Taylor, and Hobson. This fired his interest in optical physics, leading to his employment with the Ministry of Aircraft production during World War II. At the end of the war he was appointed lecturer and then reader in optics at Imperial College London.
