Biography Cook grew up in Iowa before moving to Chicago and then California. He studied pharmacy at the College of Physicians and Surgeons in San Francisco.
He was an associate of Emma Goldman, raising her bond when she was arrested in San Francisco in 1909 after she came to the city for a series of lectures and debates organized by the San Francisco Social Science League, of which Cook was a member. He later accompanied her to Seattle as part of a lecture tour.
He contributed writing to Mother Earth and was arrested for opposition to the First World War.
Later in the decade, he edited The Libertarian Magazine in Seattle.
In 1919, Cook was head of the Chicago office of the International Workers' Defence League and was involved in organizing to free or win a retrial for Thomas Mooney, who had been convicted and sentenced to death—commuted to life in prison—for the San Francisco Preparedness Day Bombing.
Between the World Wars, Cook was a member of the anarchist Libertarian Society in Los Angeles. He was described as a "large, florid, and bombastic" man, who "wrote resolutions for meetings and conventions."
Later in life, he was an advertising executive and secretary of Rocker Publications, which printed and promoted the work of Rudolf Rocker. His death was also noted by a short obituary in the London-based Freedom, an anarchist fortnightly newspaper. His papers are part of the Labadie Collection at the University of Michigan.
