In December 1962, Arnold Beckman filmed an appearance on the long-running television program Science in Action to demonstrate how some of his instruments worked.
The screen images are attributed to Juan Zec, a chemist in the Spinco Research Department; all but the largest, with Beckman's name displayed, are numbered in pencil on the reverse. The other images are attributed to Moss Photography and bear a stamp and photo number; some request that credit be given to California Academy of Sciences and Moss Photography.
