Reverend John Michell demonstrated the existence of binary stars and physical star clusters, predicted the existence of black holes, and made the first realistic estimate of the distance to a star, all major intellectual achievements for an eighteenth-century English scientist – clergyman.
Michell is thought to have been born in Nottinghamshire, perhaps on Christmas Day 1724, but that is uncertain. There are no portraits available, and only a brief description of him as “a little short man, of a black complexion, and fat” exists in a contemporary diary. It is known that he married a Sarah Williamson in 1764 but that she died the next year.
In 1742 Michell became a student at Queens’ College, Cambridge University, from which he received his MA (1752) and BD (1761) degrees. During this time he held the first of several rectorships at churches in the region.
In 1767 Michell published a paper on...
