The co-creator of A Course in Miracles is Helen Schucman, an American clinical psychologist. She is best known for her role in scribing the text of the course, which she claimed was dictated to her by an inner voice she identified as Jesus. Schucman began this process in 1965, and the course was published in 1976. Alongside Schucman, William Thetford served as her colleague and co-creator. He provided support and encouragement throughout the scribing process. Together, they aimed to present a spiritual framework that emphasizes forgiveness and inner peace, making the teachings accessible to a wide audience.
