- His NY Times obituary's second paragraph notes, "Mr. Dyson gained added prominence in 1973 when he was the fifth entry on President Richard M. Nixon's 'enemies list' of political opponents."

- Third paragraph: "Mr. Dyson, who had been hawkish on the Vietnam War until the mid-1960's, when he began opposing it, said he never knew why he had been deemed worthy of Presidential enmity. But he said at the time, "I think it was an endorsement for good standards to be on the enemies list.'"

- John Gardner (quoted in the obituary) notes that Dyson was "immensely valuable" to the Common Cause board because he was "steady, sane, and wise" while activists tended to be "articulate and impulsive."
