Horrocks, Jeremiah, 1618-1641 (astronomer)



  • Existence: 1618 - 1641


Jeremiah Horrocks (1618-41) of Emmanuel College, Cambridge, astronomer, inspired John Flamsteed in the creation of the Royal Observatory, 1675, and was named by Sir Isaac Newton as a crucial link between Kepler and his own work. Horrocks predicted a transit of Venus, and on 24th November 1639 was the first astronomer to see it, with the aid of a telescope. Horrocks worked on 'Venus in sole visa' until his death at the age of 23; it was published from another manuscript (now lost) by Joannes Hevelius in Danzig, 1662. An English translation was published in 1859.
