Artist and poet Andrew Hoyem was born to second-generation Norwegian parents in Sioux Falls, South Dakota, in 1935. He served in the U. S. Navy after graduating from college, moving to San Francisco in 1961 to work for both the Auerhahn and Grabhorn Presses. Dave Haselwood's Auerhahn Press focused on avante-garde literature, especially Beat Generation poetry until it closed in the mid-'60s. After Edwin and Robert Grabhorn closed their press in 1965, Robert partnered with and mentored Hoyem, who had no formal training. Specializing in fine printing and limited edition books, Grabhorn-Hoyem is probably best known for its 1971 edition of Allen Ginsberg's Howl. With Robert came the Grabhorn Press printing equipment and historic type collection, some of which had been acquired from John Henry Nash.
In 1973, Robert Grabhorn died, and Hoyem renamed the company Arion Press, after a legendary Greek poet. Arion expanded from literary publication to art books in the 1980s and bought the oldest, largest surviving American type foundry, Mackenzie & Harris, in 1989. Museums, libraries, and individuals collect Arion editions, which are featured in the libraries of Britain, Brown and Stanford Universities, New York City, among others, as well as exhibitions including a 1995 Museum of Modern Art exhibit. In 2001, Arion Press moved to the Presidio of San Francisco.
