Jackson Mac Low (September 12, 1922 – December 8, 2004) was an American poet, performance artist, composer and playwright, known to most readers of poetry as a practioneer of systematic chance operations and other non-intentional compositional methods in his work, which Mac Low first experienced in the musical work of John Cage, Earle Brown, and Christian Wolff. He was married to the artist Iris Lezak from 1962 to 1978, and to the poet Anne Tardos from 1990 until his death. He wrote 31 books. His work has been published in more than 90 anthologies and periodicals and read publicly, exhibited, performed, and broadcast in North and South America, Europe, Japan, Australia, and New Zealand. He read, performed, and lectured in New York and throughout North America, Europe, and New Zealand, San Francisco, Santa Cruz, Asnières, Paris, Bouliac (near Bordeaux), Marseilles, Buffalo, Philadelphia, and New York.
Mac Low received his associate's degree from the University of Chicago in 1943, where he continued study in philosophy and literature into 1945, and his bachelor's degree in Ancient Greek from Brooklyn College in 1953. From 1957 onward, Mac Low worked as an etymologist, writer of reference-book articles, copy editor, indexer, proofreader, and fact checker for many publishers, including Knopf, Funk & Wagnalls, Pantheon, Bantam, and Macmillan. Beginning in 1981, Mac Low and Anne Tardos wrote, directed, and performed in seven radioworks.
