John Willison Green

John Willison Green (born February 12, 1927) is a retired Canadian journalist and a leading researcher into the Bigfoot phenomenon. He is a graduate of both the University of British Columbia and Columbia University and has a database of more than 3000 sighting and track reports, leading some to affectionately refer to him as "Mr. Sasquatch", and in some circles as one of the "Four Horsemen of Sasquatchery".
