Sketch For Pencilite (USA), ca. 1915
Joseph Friedman’s best-known invention is the flexible straw, but the range of his inventive activities encompassed improvements to engines, household products, and writing implements, including this sketch for one of his earliest inventions for a light-up pencil, the so-called "Pencilite." Friedman frequently sketched on loose scraps of paper—he was especially fond of envelopes—working out ideas and solving problems, as here.
