William Wilfred Walter (1869-1941) was an American writer and practitioner of Eschatology, a system of beliefs which he created. At thirty Walter caught tuberculosis. In his writings he claims that after seven years of struggling using the Christian Science healing techniques he finally overcame his illness. He thus became involved in trying to heal others as a Christian Science practitioner. Between 1907 and 1910, he wrote three novels about mental healing in plain English for his clients and also for people outside the church, including The Pastor's Son (1907). In 1910 he published The Christ Way under a pseudonym. The book was relatively rejected by church members but widely accepted by outsiders. He reprinted the book, this time with his real name. Between 1912 and 1916 he wrote several more books. In 1916 he also published his first Plain Talk series booklets, which heavily drew upon Mary Baker Eddy's teaching. In the final chapter of The Sharp Sickle, the official textbook of Eschatology published in 1928, Walter sees the biblical book of Revelation as prophesizing his own work, but didn't claim any special mission from a personal God.
