Biography

Levy was born in Montreal, Quebec, Canada, in 1948. He developed an interest in astronomy at an early age. However, he pursued and received bachelor's and master's degrees in English literature.

Levy went on to discover 23 comets, either independently or with Gene and Carolyn Shoemaker. He has written 34 books, mostly on astronomical subjects, such as The Quest for Comets, a biography of Pluto-discoverer Clyde Tombaugh in 2006, and his tribute to Gene Shoemaker in Shoemaker by Levy. He has provided periodic articles for Sky and Telescope magazine, as well as Parade Magazine, Sky News and, most recently, Astronomy Magazine.

Periodic comets that Levy co-discovered include 118P/Shoemaker–Levy, 129P/Shoemaker–Levy, 135P/Shoemaker–Levy, 137P/Shoemaker–Levy, 138P/Shoemaker–Levy, 145P/Shoemaker–Levy, and 181P/Shoemaker–Levy. In addition, Levy is the sole discoverer of two periodic comets: 255P/Levy and P/1991 L3.

On February 28, 2011, Levy was awarded a Ph.D. from the Hebrew University of Jerusalem for his successful completion of his thesis "The Sky in Early Modern English Literature: A Study of Allusions to Celestial Events in Elizabethan and Jacobean Writing, 1572–1620."

Starting in 2015, Levy has been donating his observing logs, which he has kept continuously since 1956, his personal journals since 1958, and his comet search records since 1965, to the Linda Hall Library of Science Library in Kansas City. The observing records are also on-line at the website of the Royal Astronomical Society of Canada.

He lives in Vail, Arizona and was married to Wendee Levy from 1997 until her death in 2022. Levy and his wife hosted a weekly internet radio talk show on astronomy, which ended on February 3, 2011, with a planned "Final Show". Show archives are available in WMA and MP3 formats. Levy is President of the National Sharing the Sky Foundation and a Master of Astronomy with DeTao Masters Academy (DTMA).

Levy's autobiography, "A Nightwatchman's journey: the Road Not Taken" was published in June 2019 by the Royal Astronomical Society of Canada.

Awards

The main-asteroid 3673 Levy was named in his honour. Levy was awarded the C.A. Chant Medal of the Royal Astronomical Society of Canada in 1980. Levy was recipient of the 1990 G. Bruce Blair Medal. In 1993 he won the Amateur Achievement Award of the Astronomical Society of the Pacific. In 2007, Levy received the Smithsonian Astrophysical Observatory's Edgar Wilson Award for the discovery of comets. In 2008, a special edition telescope, "The Comet Hunter" was co-designed by Levy.

Together with Martyn Ives, David Taylor, and Benjamin Woolley, Levy won a 1998 News & Documentary Emmy Award in the "Individual Achievement in a Craft, Writer" category for the script of the documentary 3 Minutes to Impact produced by York Films for the Discovery Channel.
