    Thomas Hood, the mathematician and physician, was baptised on this day in history, 23rd June 1556, at St Leonard Eastcheap. It was usual for children to be baptised within a few days of birth so he was also born in June 1556. His father was merchant taylor Thomas Hood.

In 1585, he was granted a licence to practise medicine by Cambridge University. In late 1588, he became Mathematical Lecturer to the City of London and he lectured on the subject until 1592. His biographer, H.K. Higton, writes of how “In the aftermath of the Spanish armada of 1588, concern for a greater knowledge of the mathematical sciences among military officers and naval commanders was voiced by members of the privy council” and that was the reason Hood was employed to lecture on mathematics.
