Over a long career Jan Schreiber has been active as a social scientist, a poet, and a literary critic. His book on terrorism, The Ultimate Weapon, is still cited by scholars, but in recent years he has become best known for his poems (e.g. Wily Apparitions or the recent Peccadilloes) and for incisive essays on contemporary poetry and poetics. Many of these essays are collected in his critical volume, Sparring with the Sun: Poets and the Ways We Think about Poetry in the Late Days of Modernism. A co-host of the Symposium on Poetry Criticism at Western State Colorado University, Dr. Schreiber teaches in the Osher Lifelong Learning Institute at Brandeis University.
