William "Bill" Everson (September 10, 1912 – June 3, 1994), also known as Brother Antoninus, was an American poet of the San Francisco Renaissance and was also a literary critic and small press printer.
Everson was born in Sacramento, California. His Christian Scientist parents, both of whom were printers, raised him on a farm outside the small fruit-growing town of Selma, which is south of Fresno in California's San Joaquin Valley. He played football at Selma High School and attended Fresno State College (later California State University, Fresno).
Everson was an influential member of the San Francisco Renaissance in poetry and worked closely with Kenneth Rexroth during this period of his life. Throughout his life, Everson was a devotee of the work and lifestyle of poet Robinson Jeffers. Much of his work as a critic was done on Jeffers's poetry.
Everson registered as an anarchist and a pacifist with his draft board, in compliance with the 1940 draft bill. In 1943, he was sent to a Civilian Public Service (CPS) work camp for conscientious objectors in Oregon. In Camp Angel at Waldport, Oregon, with other poets, artists and actors such as Kemper Nomland, William Eshelman, Kermit Sheets, Glen Coffield, George Woodcock and Kenneth Patchen, he founded a fine-arts program in which the CPS men staged plays and poetry-readings and learned the craft of fine printing. During his time as a conscientious objector, Everson completed The Residual Years, a volume of poems that launched him to national fame.
