NEW YORK (AP) — Tony Schwartz, who helped create the infamous "daisy ad" that ran only once during the 1964 presidential race but changed political advertising forever, has died.

Schwartz, 84, died Sunday at his Manhattan home, said his daughter Kayla Schwartz-Burridge. He had been suffering from heart valve stenosis.

The ad made for Lyndon B. Johnson's presidential campaign showed a little girl counting aloud as she removed the petals of a daisy. The scene then changed into a countdown to an atomic blast, with a voiceover from the Democratic incumbent.

The ad was withdrawn after an outcry from Johnson's opponent, Arizona Sen. Barry Goldwater, and from the public.
