International Business Machines® Patent Print "IBM" Arthur Dickinson, November 17, 1942. Arthur Dickinson was IBM's top associate and a world-beating inventor. He submitted an application for a patent for certain improvements in accounting apparatus using a "transmission system for statistical data". In fact, the patent represented a turning point in computing history. Dickinson had invented a method for adding and subtracting using vacuum tubes—a basic building block of the fully electronic computers that began to appear in the 1940s and transformed the world of business in the 1950s. This pattern of using innovation to create intellectual property is evident throughout IBM’s history. Want to know more about the International Business Machines® Patent Print?
