- “Dr. James Bradley was the third son of William and Jane Bradley, and was born at Sherborne in Dorsetshire in the year 1692.He was fitted for the university at North Leach [at] a boarding school... and from [there] he was sent to Oxford.”
- “About the fame time the chair of at Oxford became vacant, by the death of the celebrated Dr. Keil; and Mr. Bradley was elected to succeed him on the 31st of October 1721, being then just nine and twenty years old; and his colleague was Mr. Halley, who was professor of Geometry on the same foundation.”
- “Bradley, upon his being elected into this professorship, gave up both his livings, and with great joy quitted a situation in which his duty was directly opposite to his inclination.From this time he applied himself wholly to the study of his favourite science, and in the year 1727, he published his theory of the aberration of the fixed stars, which is allowed to be one of the most useful and ingenious discoveries of modern astronomy.”
- “Such is the ingenious Theory of the Aberration, which Mr. Bradley published in the year 1727, and which was received by the whole learned world with the applause that it merited. M. Clairaut, of the acedemy of sciences at Paris, afterwards made this discovery the subject of a Memoir, which he printed in 1737: In this Memoir, he examines the principles on which the Theory of the Aberration is founded, and gives the necessary rules for putting it in practice.”

Encyclopedic overview
James Bradley (September 1692 – 13 July 1762) was an English astronomer and priest who served as the third Astronomer Royal from 1742. He is best known for two fundamental discoveries in astronomy, the aberration of light (1725–1728), and the nutation of the Earth's axis (1728–1748).
These two discoveries were called "the most brilliant and useful of the century" by Jean Baptiste Joseph Delambre, historian of astronomy, mathematical astronomer and director of the Paris Observatory. In his History of astronomy in the 18th century (1821), Delambre stated: "It is to these two discoveries by Bradley that we owe the exactness of modern astronomy. ... This double service assures to their discoverer the most distinguished place (after Hipparchus and Kepler) above the greatest astronomers of all ages and all countries."
