Paul Marshall Allen (1913-1998) was an authority on the life and work of Rudolf Steiner and, as the "first American-born anthroposophic lecturer," was a leading pioneer of Rudolf Steiner's spiritual science across North America. He edited and wrote introductions for numerous books on Anthroposophy and spiritual wisdom, including his classic work, A Christian Rosenkreutz Anthology (1968), and wrote Vladimir Soloviev: Russian Mystic (1968). With his wife Joan deRis Allen, Paul coauthored Francis of Assisi's Canticle of the Creatures (1996); Fingal's Cave, the Poems of Ossian, and Celtic Christianity (1999); and The Time Is at Hand! (1995).
