From the Times obit:
“Media consultant” is barely adequate to describe Mr. Schwartz’s portfolio. In a career of more than half a century, he was variously an art director; advertising executive; urban folklorist who captured the cacophony of New York streets on phonograph records; radio host; Broadway sound designer; college professor, media theorist and author who wrote books about the persuasive power of sound and image; and maker of commercials for products, candidates and causes. What was more, Mr. Schwartz, who had suffered from agoraphobia since the age of 13, accomplished most of these things entirely within his Manhattan home.
Of the thousands of television and radio advertisements on which Mr. Schwartz worked, none is as well known, or as controversial, as one that was broadcast exactly once: the so-called “daisy ad,” made for Lyndon B. Johnson’s presidential campaign in 1964.
Produced by the advertising agency Doyle Dane Bernbach in collaboration with Mr. Schwartz, the minute-long spot was broadcast on Sept. 7, 1964, during NBC’s “Monday Night at the Movies.” It showed a little girl in a meadow (in reality a Manhattan park), counting aloud as she plucks the petals from a daisy. Her voice dissolves into a man’s voice counting downward, followed by the image of an atomic blast. President Johnson’s voice is heard on the soundtrack:
“These are the stakes. To make a world in which all of God’s children can live, or to go into the dark. We must either love each other, or we must die.”
