# William J. Breed

William J. "Bill" Breed (August 3, 1928 – January 22, 2013) was an American geologist, paleontologist, naturalist and author in Northern Arizona. He was a renowned expert on the geology of the Grand Canyon.

## Personal life

William J. Breed was born August 3, 1928, in Massillon, Ohio, son of Grace Amelia (née Snyder) and Earl Fremont Breed. After graduating from Massillon Washington High School, he served in the U.S. Army Corps of Military Police in South Korea and Japan (1946–48). He received his B.A. from Denison University, then his B.S. and M.S. from University of Arizona, finishing in 1960. He married Carol S. Breed daughter of James Neilson (director) and Mrs. Ruth Swope (née Rogers) in 1965. The couple had one daughter, Amelia, who joined the family of four girls (Linda, Laura, Grace, Pamela) from Carol's first marriage.
Upon his death in 2013 he was buried at the Grand Canyon Pioneer Cemetery.

## Career

Bill Breed was a Fulbright Scholar at Canterbury University in Christchurch, New Zealand to study geomorphology in 1957–58.
Bill Breed was a protégé of Edwin D. McKee. Breed was Curator of Geology (1960–78), Head, Geology Department (1978–81) at the Museum of Northern Arizona in Flagstaff, Arizona. In 1969, Breed and Edwin H. Colbert were two of the four vertebrate paleontologists in Antarctica who helped solidify the acceptance of continental drift theory, by finding a 220-million-year-old fossil of a Lystrosaurus. In the 1970s, Breed completed numerous publications on the Grand Canyon, including a geologic cross section map of the Grand Canyon, San Francisco Peaks and Verde Valley; and the book, Geology of the Grand Canyon.
A species of Dilophosaurus, (D. breedorum), discovered by Sam Welles in Arizona in 1964 was named after William J. Breed and his wife at the time Carol S. Breed. This name came out in a private publication distributed by Pickering, but has not been accepted in other reviews of the genus.
After leaving the Museum of Northern Arizona in 1981, Breed became a naturalist guide for Nature Expeditions International and Betchart Expeditions leading trips to Alaska, New Zealand, Galapagos, Namibia, and Australia. He became Curator Emeritus of the Museum of Northern Arizona in 2004. In January 2013, shortly before his death, Breed was named a Distinguished Fellow of the Museum of Northern Arizona.
Breed was an active environmentalist with Ted Danson and many others.
