Oh wow, today is #AlanTuring's birthday.
Turing was a mathematician and computer scientist. Literally literally all electronic computers (including smartphones) are based on stuff he worked out.
He led the UK's codebreaking efforts at Bletchley Park, and it is estimated his genius shortened World War II by two years.
After the war, he was convicted of homosexuality and sentenced to chemical castration. This drove him to suicide.
Rest in Power this #PrideMonth, Dr. Turing.
