ERNEST SHURTLEFF HOLMES (January 21, 1887 - April 7, 1960) was an American New Thought writer, teacher, and leader. He was the founder of a Spiritual movement known as Religious Science, a part of the greater New Thought movement, whose spiritual philosophy is known as “The Science of Mind.” Born in Lincoln, Maine, to Anna Columbia (Heath) and William Nelson Holmes, Holmes left school and his family for Boston at the age of 15. From 1908-1910 he attended the Leland Powers School of Expression in Boston, where he was introduced to Mary Baker Eddy’s Science and Health, as well as Christian Science. In 1912 Holmes joined his brother Fenwicke, a Congregationalist minister, in Venice, California; the brothers studied another New Thought teaching, Divine Science, and Holmes was an ordained Divine Science Minister. In 1916 Holmes was invited to speak at the Metaphysical Library in Los Angeles, leading to further engagements and a nationwide tour. In 1919 he published his first book, The Creative Mind, and toured for almost a decade before settling in L.A. to complete his major work, The Science of Mind, which was published in 1926. Numerous other metaphysical books followed, and he founded the Science of Mind magazine in 1927. He died in L.A. in 1960, aged 73.
