1886 English organic chemist Robert Robinson was born near Chesterfield, Derbyshire. He was awarded the 1947 Nobel Prize in Chemistry for his research on plant dyestuffs (anthocyanins) and alkaloids. He invented the symbol for benzene whilst working at St Andrews University in 1923. He is known for inventing the use of the curly arrow to represent electron movement, and he is also known for discovering the molecular structures of morphine and penicillin.
1851 American Army physician Walter Reed was born in Belroi, Virginia. In 1900, he led the team that postulated and confirmed the theory that yellow fever is transmitted by a particular mosquito species, rather than by direct contact. This insight gave impetus to the new fields of epidemiology and biomedicine, and most immediately allowed the resumption and completion of work on the Panama Canal (1904–1914) by the United States.
