In 1855, Ralph Waldo Emerson wrote in his Journal: “If a man has good corn, or wood, or boards, or pigs, to sell, or can make better chairs or knives, crucibles, or church organs, than anybody else, you will find a broad, hard-beaten road to his house, though it be in the woods.” In time, his words were somehow conflated as the oft-cited quote: “Build a better mousetrap, and the world will beat a path to your door.” Carina Ramirez Cahan is testing Emerson’s thesis, having worked with her husband, a respected breast surgeon, to build a better bra. Relying on a patented polymer insert that eliminates the need for rigid underwires, Carina promises that her bra will be the most comfortable, supportive, and flattering bra her customers have ever worn. But as she tells roving reporter Rotbart — a lesson relevant to all budding inventors and entrepreneurs — she’s still awaiting the hoard of customers that Emerson forecast.
