John Field (astronomer)
John Field or Feild, was a "proto-Copernican" English astronomer. Field was the son of Richard Field. He was born, it is supposed, at Ardsley in the West Riding of Yorkshire between 1520 and 1530. He received a liberal education, and Joseph Hunter, his descendant, conjectured that part of it was gained under the patronage of Alured Comyn, Prior of Nostell, from which house the cell of Woodkirk, near Ardsley, depended. Anthony à Wood believed that he studied at Oxford.
He was living in London at the date of his first Ephemeris, and appears, from a remark in a manuscript in Lambeth Palace Library, to have been a public instructor in science.
