When Bell invented the telephone in 1876, President Rutherford said, "That's an
invention, but who would ever want to use one of them?" In the 1940s, another young
named Carlson took his idea to 20 corporations,
some of the biggest in the country. They all turned him down. In 1947 — after seven long years of rejections! - He
