He is best known for his book The Third Man Factor: Surviving the Impossible, which popularized the concept of the "Third Man", an incorporeal being that aids people under extreme duress. The book is the basis for National Geographic Channel's Explorer: The Angel Effect, in which Geiger appears. A book of the same name was published in 2013.

His four other books of non-fiction include the international bestseller Frozen In Time: The Fate of the Franklin Expedition. He was the editorial board editor for The Globe and Mail, a senior fellow at Massey College, and is currently the chief executive officer (former president) of the Royal Canadian Geographical Society. Geiger was born in Ithaca, New York, grew up in Edmonton, Alberta, and studied history at the University of Alberta.

John Geiger is currently the CEO of the Royal Canadian Geographical Society.

In September 2014, John Geiger was a participant in the Victoria Strait Expedition that searched for Sir John Franklin's ships HMS Erebus and HMS Terror. The HMS Erebus was successfully located, though Geiger himself was not among the search crew who found it.

In 1987, Bloomsbury Publishing released Frozen In Time: The Fate of The Franklin Expedition, written by Owen Beattie and John Geiger, with a revised edition in 2004 that featured an introduction by Margaret Atwood. The book has been published in seven countries and became a bestseller in the United Kingdom, and subsequently in Canada and Germany. Geiger spent three field seasons in the Arctic as historical investigator for the Knight Archeological Project, a scientific investigation of the 1719 James Knight Expedition disaster, research published as Dead Silence in 1993. Geiger's book Chapel of Extreme Experience: A Short History of Stroboscopic Light and the Dream Machine (2003) was made into an award-winning film FLicKeR, by director Nik Sheehan. It contains a foreword by the writer and socialite Leila Hadley. Nothing Is True Everything Is Permitted: The Life of Brion Gysin was published in 2005.
