O'Leary was born and raised in Boston, Massachusetts on January 27, 1940. He decided to become an astronaut after visiting Washington, D.C. as a teenager.[2] On December 1, 1983, O'Leary was married to Delores Marie Lefkowitz, also known as Dee Davenport, in Yarmouth, Massachusetts.[3]
O'Leary became politically active early in his career and participated in a demonstration in Washington, D.C. in 1970, to protest the Cambodian Campaign. Richard Nixon administration officials invited O'Leary and his fellow Cornell professors to present their views.[34][35] In 1975 and 1976, he worked on Morris Udall's presidential campaign as an energy advisor, as well as for the U.S. House Interior Committee subcommittee on energy and the environment as Udall's special staff consultant on energy.[20] O'Leary worked for U.S. presidential candidates Jesse Jackson, Dennis Kucinich, George McGovern, and Walter Mondale.[9][36]
A remote viewing experience in 1979[43] and a near-death experience in 1982[44] initiated O'Leary's departure from orthodox science. After Princeton, O'Leary worked at Science Applications International Corporation.[20] He refused to work on military space applications, for which reason he lost his position there in 1987.[45] Beginning in 1987, O'Leary increasingly explored unorthodox ideas, particularly the relationship between consciousness and science, and became widely known for his writings on "the frontiers of science, space, energy and culture".[20][46]
With artist Meredith Miller, his third wife and widow, he co-founded the Montesueños Eco-Retreat in Vilcabamba, Ecuador in 2008, which is devoted to "peace, sustainability, the arts and new science".[49]
Death
O'Leary contracted skin cancer in his 60s, which he treated with an alternative methodology involving a substance called Cansema. After surviving his second heart attack (precipitated by an ayahuasca ceremony)[50] in 2010, he died of intestinal cancer on July 28, 2011, soon after diagnosis, at his home in Vilcabamba.
