Researching James Bradley

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."

On June 23, 2016, the Marine Corps announced after an investigation, that John Bradley was not in Rosenthal's photograph of six Marines raising the second (and larger) flag on Mount Suribachi on February 23, 1945, although he had been involved in the first raising of a smaller flag two hours earlier, and was still on the mountaintop during the second flag raising.

Bradley's novels, which have been published internationally, explore both past and future. His books include seven novels and a book of poetry. He has also edited two anthologies, Blur, a collection of writing by young Australian writers, and The Penguin Book of the Ocean. Bradley also writes as a critic, with reviews and articles appearing regularly in Australian newspapers and magazines, and blogs at City of Tongues.

In 2012 he won the Pascall Prize for Criticism and was named Australian Critic of the Year.

He lives in Sydney with his partner, the novelist Mardi McConnochie.

Bradley made his first-class debut for Nottinghamshire against Surrey in the 1937 County Championship. He made eight further first-class appearances for the county, the last of which came against Kent in the 1939 County Championship. In his nine first-class appearances for the county, he took 19 wickets at an average of 41.10, with best figures of 4/116. With the bat, he scored 30 runs at a batting average of 6.00, with a high score of 13.

He died at Mansfield, Nottinghamshire in January 2001, aged 87.

He graduated from Cornell University (A.B. 1906, Ph.D. 1910) and the University of California (M.S. 1907). He was an assistant professor of entomology at Cornell from 1911–1920, and professor and curator of invertebrate zoology from 1920-1952.

James Chester Bradley wrote very many entomological papers. He is especially known for his works on Evaniidae and Scoliidae.
