Steve McCaffery was born January 24, 1947, in Sheffield, England. He came to Canada partly to work with bpNichol, and the two poets formed the Toronto Research Group. McCaffery and Nichol also combined talents with Paul Dutton and Rafael Barreto-Rivera as the Four Horsemen, creating and performing innovative sound poetry. During the seventies and eighties, he and Nichol were regular contributors to the poetic journal Open Letter. McCaffery's collection of critical writings, North of Intention, stands as one of the earliest and best collections of essays about experimental writing in Canada and the U.S., and it demonstrates and explores McCaffery's own affiliation with the practitioners of the so-called Language Poetry and poetics, often considered a uniquely American phenomenon. McCaffery recently completed his PhD at SUNY Buffalo and is now teaching at York University.
