John Klein was born in Detroit and grew up on the west side of Chicago.
Writing fiction has been one of Klein's life-long passions. While in college, he had set his goals on a career as a writer, only to be 'temporarily' side-tracked with an excursion into science. Throughout that time, however, he continued to write short stories, novels, poems, and plays.
After graduating with a BA from Elmhurst College, Klein went on to earn a PhD from The Johns Hopkins University in Baltimore, MD. He did postdoctoral work at The University of Pennsylvania in Philadelphia, PA, the Massachusetts Institute of Technology in Cambridge, MA, and The Scripps Clinic and Research Foundation in La Jolla, CA.
Klein's debut novel, Frankie Jones, a book of literary fiction that was widely-received and critically acclaimed, was released in 2016. F. Scott Fitzgerald said, 'Show me a hero and I will write you a tragedy'. Nothing could better describe Frankie Jones. He is the quintessential American who comes from humble origins, lives in the moment, and succeeds out of sheer determination. It is the story of a heroic but flawed character.
The Ostermann House, a psychological thriller with a touch of paranormal suspense, is set in a small town in rural Texas. It was released in June 2017. Awards include: 2017 Killer Nashville Claymore Award Finalist, Best Book of 2017 by Advice Books International, and finalist in the Eric Hoffer da Vinci Eye Awards in 2018.
While living in Del Mar, California", Klein wrote, To Find - The Search for Meaning in Life on the Gringo Trail, a memoir of his travels in Mexico and Central America on less than five dollars a day.
Klein has traveled through more than two dozen countries on four continents, including a trip up the Amazon River on a cargo boat.
