John Irvan Boslough was born June 18, 1942, in Charlotte, N.C., and later moved with his family to Denver. He graduated from East High School and earned a history of science degree at Princeton University. He worked as a logger, crab fisherman and construction worker in Alaska for two years.
He was editor of the Mountain Mail newspaper in Salida and worked at The Associated Press before joining The Post in 1974, where he worked until 1978. Part of his time with The Post he worked at the paper’s Washington, D.C., bureau.
He married Susan Raehn on Sept. 23, 1989.
Boslough loved science and covered the subject for The Denver Post and for U.S. News and World Report.
His Stephen Hawking book, “Beyond the Black Hole — Stephen Hawking’s Universe,” was translated into 10 languages and has been used in high school and college science classes, said his brother, Jim Boslough of Billings, Mont.
With astrophysicist John C. Mather, Boslough co-wrote two books, one on cosmology and another about a scientific journey back to the dawn of the universe.
