I was born in 1948 and raised in the suburbs of Cincinnati, closely adjacent to a hardwood forest, in which I spent much of my boyhood.  Then bulldozers came and scraped the forest away, a formative experience.  In 1973, after education at Yale and Oxford and the publication of one novel, I moved to Montana, not foreseeing I would stay there a lifetime.  My second book, a spy novel, appeared in 1983.  Another spy novel, The Soul of Viktor Tronko, based on historical events in the case of a certain Russian defector, was published by Doubleday in 1987 and sank like a hot pistol tossed into the Potomac.  Blood Line: Stories of Fathers and Sons was published by Graywolf a year later.  Meanwhile I had transmogrified into a nonfiction writer.

In 1981 I began as a columnist for Outside Magazine and continued that role for fifteen years.  Selections of the columns, along with some longer pieces done for Outside and other magazines, comprise my four books of short nonfiction: Natural Acts (1985), The Flight of the Iguana (1988), Wild Thoughts from Wild Places (1998), and The Boilerplate Rhino (2000).  A revised, culled, and re-expanded edition of Natural Acts was published by W.W. Norton in 2008.  My three full-length nonfiction books are The Song of the Dodo (1996), Monster of God (2003), and The Reluctant Mr. Darwin (2006).  A fourth, to be titled Spillover, is in progress.

In 1999 I was asked by National Geographic Magazine to write a series of three stories about J. Michael Fay's epic 2000-mile survey hike through the forests of Central Africa, an expedition that became known as the Megatransect.  I walked for eight weeks with Fay across portions of the Congo and Ogooué river basins.  After my feet healed and those stories had run, I continued working for National Geographic and now hold a position as Contributing Writer.  In 2004 I wrote the National Geographic cover story “Was Darwin Wrong?,” which won the third of my National Magazine Awards.

I've received honorary doctorates from Montana State University and Colorado College.  I have also been helped materially along the way, in my education and in my leaner freelancing years, by a Rhodes scholarship, a Guggenheim fellowship, and a Lannan Literary Award for nonfiction.  From 2007 to 2009 I served as Wallace Stegner Professor of Western American Studies (a rotating, three-year gig by definition) at Montana State University.  I live in Bozeman with my wife, Betsy Gaines Quammen, founding director of The Tributary Fund, a conservation organization that collaborates with religious leaders in Mongolia and elsewhere.  Having retired from whitewater kayaking and ice hockey, the diversions of my impetuous middle age, I continue to bicycle and ski.  Telemark: free your heels, etc.  I also spend quite a lot of time walking two large, white dogs.
