Thomas Wm. Hamilton knew he wanted to be a writer since he was young. “When I was 11 years old and I didn’t like the way Mark Twain ended Tom Sawyer Abroad, I decided to write my own ending.” Born in San Francisco, the author grew up in New York and New Hampshire. He is a retired astronomer who taught in college for 32 years, worked in several planetariums, and worked on the Apollo Project. In 2009 the International Astronomical Union recognized his contributions to the field of astronomy by naming asteroid 4897 Tomhamilton. In 2010 the International Planetarium Society at its conference held in Alexandria, Egypt, designated him as a Fellow of the Society. His earlier books were nonfiction. He lives on Staten Island, New York, and is working on his next astronomy book.
