A deeper antagonism between Teller and many of his former colleagues developed when J. Robert Oppenheimer was accused of disloyalty on the basis of some past associations. Teller made no accusations himself, but when Oppenheimer's security clearance was revoked, many of his friends blamed Teller. Over the years, Teller continued to advocate a strong national defense. He made headlines in the 1970s, promoting the development of nuclear fusion as an alternative to other sources of energy, and again in the 1980s, testifying in favor of the strategic missile defense system. He was the author of over a dozen books, mostly dealing with nuclear energy and defense issues. From 1975, Edward Teller was a senior research fellow at the Hoover Institute for the Study of War, Revolution and Peace at Stanford University in Palo Alto, California. He died at his home on the University campus at the age of 95.
