Hungarian-born physicist Edward Teller was among the great scientists of the 20th century, but his legacy is, at best, a checkered one. Made famous by his work on thermonuclear weapons -- Teller is known as the "father of the hydrogen bomb" -- Teller gained notoriety when he testified against his former colleague J. Robert Oppenheimer in the hearing that ultimately cost Oppenheimer his security clearance. Teller continued to embroil himself in controversy -- generally pertaining to thermonuclear weapons and other defense issues -- throughout his life.
