Jim Mason

Jim Mason (born September 30, 1940) is an American lawyer, journalist and animal rights activist.

Mason was born in Superior, Wisconsin on September 30, 1940. He grew up in rural Missouri on a farm. He was educated at the University of Washington. He dropped out and spent the next two years traveling in New York and New England before joining the United States Army. After he completed his military service, Mason attended the University of Missouri where he obtained his J.D. degree. He formed his own law practice in Bridgeport in 1973.

Mason was introduced to philosopher Peter Singer in 1974. The next year they began discussing the possibility of collaborating on a book-length treatment of factory farming. Mason did much research on factory farming and travelled around the United States and Canada visiting intensive farming facilities. Their book Animal Factories was first published in 1980 and revised in 1990. It provides a critical review and photographic documentation of factory farming practices in North America. The book is known for having "played a role in the United States similar to that of Harrison's book in the United Kingdom and Europe in providing a critical expose of the factory farm system."

He was elected to the U.S. Animal Rights Hall of Fame in 2001. Mason is a vegan.
