The University of Wisconsin has archived hundreds of press clippings, and press releases from Harry Harlow's heyday in the 1960s in particular. To give a sense of the popular appeal of his work, I'd like to cite: John Kord Lageman, “What Monkeys Are Teaching Science About Children,”

The first paper published on the studies of monkey family support systems was “Nuclear Family Apparatus,” Margaret K. Harlow,
