The circumstances that prompted Jim Wilden to develop the air-operated double-diaphragm (AODD) pumping principle six decades ago have taken on almost mythic status: a ruptured water pipe, a flooded workshop, and an exclamation from a coworker that “Slim” (Wilden’s nickname) could “make a million dollars” if he could invent a solution.
