Samuel Renshaw

Renshaw became involved in the establishment of the Midwestern Psychological Association and served as the organization's Secretary-Treasurer in 1929. For his contributions to the war effort the United States Navy awarded him the Navy Distinguished Public Service Award in 1955. He wrote 23 volumes of a journal Visual Psychology.

Science fiction writer Robert A. Heinlein depicted the technique in several of his works, including the novel Citizen of the Galaxy (1957) and the novella Gulf (1949); he mentioned Renshaw in the context of the training of Fair Witnesses in his novel Stranger in a Strange Land (1961), a bestseller. He cited a Saturday Evening Post article on Renshaw's studies for responses to fan mail about the subject.

This technique and equipment appeared at the Ravenswood School District (near Stanford University) for a short time in the 1960s. Several young students took part in the experiment, which involved film-strip readers and page-at-a-glance equipment.

The "Renshaw Training System for Aircraft and Ship Recognition" is considered to have "saved untold lives during World War II".
