'''William Kenneth Hartmann''' (born June 6, 1939) is a noted [[Astronomy:Planetary science|planetary scientist]], artist, author, and writer. He was the first to convince the scientific mainstream that the Earth had once been hit by a planet sized body ([[Astronomy:Theia (planet)|Theia]]), creating both the [[Astronomy:Moon|Moon]] and the Earth's 23.5° tilt.<ref name=Cat1>''Birth of the Planet, November 24, 2008, Channel 4</ref>

==Early life and education==
Hartmann was born in Pennsylvania in 1939.<ref name="google">{{cite book |title=Contemporary Authors: New Revision Series |author=Watson, T. |date=2005 |publisher=Cengage Gale |isbn=9780787678944 |url=https://archive.org/details/isbn_9780787667238 |url-access=registration |access-date=2015-01-31}}</ref> He was awarded a Bachelor of Science degree (B.S.) in physics from [[Organization:Pennsylvania State University|Pennsylvania State University]], and both a Master of Science degree (M.S.) in [[Earth:Geology|geology]] and [[Social:Doctor of Philosophy|Doctor of Philosophy]] (PhD) in [[Astronomy:Astronomy|astronomy]] from the [[Organization:University of Arizona|University of Arizona]].

==Career==
Hartmann's career spans over 40 years, from work in the early 1960s with Gerard Kuiper on [[Astronomy:Mare Orientale|Mare Orientale]], and work on the [[Astronomy:Mariner 9|Mariner 9]] Mars mapping project, to work on the [[Astronomy:Mars Global Surveyor|Mars Global Surveyor]] imaging team. He is currently a senior scientist at the [[Organization:Planetary Science Institute|Planetary Science Institute]].

He has long been one of America's leading [[Engineering:Space art|space art]]ists (strongly influenced by Chesley Bonestell), and has written and illustrated numerous books on the [[Earth:History of Earth|history of Earth]] and the [[Astronomy:Solar System|Solar System]], often in collaboration with artist Ron Miller.

Hartmann is a Fellow of the International Association of Astronomical Artists. His written work also includes textbooks, short fiction, and novels, the most recent being published in 2003. In 1997 he was the first recipient of the ''Carl Sagan Medal for Excellence in Public Communication in Planetary Science'' from the American Astronomical Society, [[Organization:Division for Planetary Sciences|Division for Planetary Sciences]].

Hartmann was a member of the 1966–1968 University of Colorado UFO Project (informally known as the Condon Committee), a controversial{{citation needed|date=November 2016}} public study of [[Unsolved:UFO|UFO]]s sponsored by the U.S. Air Force. He primarily investigated photographic evidence, and rejected most as unreliable or inconclusive; in his studies published in the Committee's final report, he concluded two cases - Great Falls (motion pictures of two bright light sources difficult to reconcile with known aircraft) and McMinnville (two photographs of a saucer-shaped craft)<ref>Condon Report: Scientific Study of Unidentified Flying Objects (1968), 119.</ref> - were unexplained and particularly noteworthy as probative evidence of the reality of UFOs.

Asteroid [[Astronomy:3341 Hartmann|3341 Hartmann]] is named after him.
