Make: Inventing a Better Mousetrap - On April 10, 1790, president George Washington signed a patent bill that recognized the right of an inventor to profit from his or her invention. There was a caveat: In order to receive a patent, the inventor first had to submit a small reproduction of the invention in question. For the next 90 years, inventors dutifully and ingeniously created small-scale replicas of their larger vision, many of which were displayed for the public to admire. In 1880, the model stipulation was amended and inventors no longer needed to invent their ideas in miniature. But by then, some 200,000 patent models had been built and submitted, many of which are still around today. Through fascinating historical tales, Mousetrap chronicles the stories, challenges, and triumphs of our country's first Makers.
