Robert Allan Monroe was born in 1915 in
Indiana and grew up in
Lexington, Kentucky, and
Columbus, Ohio. His mother was a non-practicing medical doctor,
cellist, and
piano player. His father was a professor of
Romance Languages who led summer tours to Europe. According to his third book
Ultimate Journey, he dropped out of
Ohio State University in his sophomore year due to a hospital stay for a facial burn that caused him to fall behind in his studies. During almost a year away from college, he tried to find work. He returned to Ohio State to graduate after having studied
pre-med, English, engineering and journalism. He married Jeanette, a graduate student and daughter of a lawyer, in 1937, and divorced her in 1938 or 1939. He married Mary Ashworth, a divorcee with a daughter Maria, in 1950 or 1951. They had Bob's only biological child together, daughter Laurie. They divorced in 1968. He then married Nancy Penn Honeycutt, a divorcee with four children. They remained married until her death from breast cancer on August 15, 1992. Monroe developed ulcers in young adulthood and so was classified
4F (unfit for service) during
World War II. He spent the war years working for a manufacturing company that designed a flight-simulator prototype. He wrote for an aviation column in
Argosy magazine and was given a job with the
National Aeronautic Association (NAA), for whom he produced a weekly radio show called "Scramble!", the primary purpose of which was to interest youth in aviation. In 1953, Monroe formed RAM Enterprises, a corporation that produced network radio programs, as many as 28 programs monthly, principally in dramatic and popular quiz shows. In 1956, the firm created a Research and Development division to study the effects of various sound patterns on human consciousness, including the sleep state. Monroe was especially attracted to the concept of
sleep-learning. This was a natural direction to take, applying to this new area the audio production methods used in the firm's commercial activity. The purpose was to find more constructive uses for such knowledge than was ordinarily available, and the results of this research have become internationally known. ==Out-of-body experiences==
