John David Buchanan grew up in San Antonio, Texas in a military family, went to Southwest Texas University, and upon graduating with a Masters Degree in Science, worked as an environmental specialist for 26 years. He started and ran his own firm, Buchanan Environmental Associates, for 18 years. Now, he's a writer and musician, and also the chef, yard boy, pool boy and handyman at his home in Humble, Texas.

Buchanan published three science fiction books as part of his Jump Starting the Universe Series, and while working on book three of that series, got the idea for his new book, The Obsession of Dr. Pendergrass.  He never enjoyed history in school, but then, he made a trip to England with his wife and visited Hastings. He's been interested in history ever since. He's traveled to London several times, and loved it every time he went.  So, using it as the location of this story seemed perfect.
