During his hearing, Oppenheimer testified on the left-wing activities of ten of his colleagues and previous acquaintances, mostly in reference to activities in the late 1930s. These ten people's activities were already public knowledge through prior hearings and activities (such as Addis, Chevelier, Lambert, May, Pitman, and I. Folkoff) or already known to the FBI. Some believe that had his clearance not been stripped, he might have been remembered as someone who "named names" to save his own reputation, but as it happened, most in the scientific community saw him as a martyr to McCarthyism, an eclectic liberal unjustly attacked by warmongering enemies, symbolic of the shift of scientific work from academia into the military. Wernher von Braun told a Congressional committee: "In England, Oppenheimer would have been knighted."
