Joseph Murphy (1898-1981) was an Irish-born author, lecturer, and minister associated with the New Thought movement. Educated in Ireland and later active in the United States, Murphy became widely known for his teachings on the power of the subconscious mind and the influence of belief on personal experience. His books, lectures, and radio programs reached millions of readers and listeners, helping popularize ideas about mental discipline, positive thinking, and spiritual psychology. The Power of Your Subconscious Mind remains his most widely read and enduring work.
