Dictionary of National Biography, 1885-1900/Chillingworth, John (d.1445)
CHILLINGWORTH, JOHN (d. 1445), astronomer, trod in the footsteps and inherited the fame of his predecessor of the same name, with whom he has sometimes been confounded. Like him, he was a fellow of Merton College, Oxford, and like him he cultivated with especial predilection mathematical studies. This titles of his works, however, have not been transmitted to us, and it is doubtful whether he may not have had the credit of some of his predecessor's work. He is stated to have been a native of Northumberland, was principal of St. John's Hall in 1440, and junior proctor of the university in 1441. He died 17 May 1445, and was buried outside the chapel of Merton College. His will was proved 25 May 1445. Anthony à Wood testifies that he was 'a great astronomer of his time, as his works have showed, having been a zealous follower and admirer of John Chillingworth, sometime fellow of his college, and in renown in the century going before.
