This drawing by William Seward Burroughs is from his first patent application for a calculating machine—an important step toward the modern computer. A sometime clerk, box maker, and mechanic, Burroughs resolved to invent a machine that could add automatically and print the result. He was issued the patent on August 21, 1888.
