Coney Island was chiefly an amusement and often a raffish one, but there was a serious side to some of the sights. For instance, Topsy the elephant was electrocuted in 1903 in what may have been a scheme to make Nikola Tesla’s AC system seem dangerous, giving Thomas Edison’s DC method positive publicity during the War of the Currents. The baby incubators were likewise a suspect attraction, though it would seem much good came of the spectator-sponsored medical innovation, which, if its proprietor, Dr. Martin A. Couney, is to be believed, successfully graduated 6,000 babies by 1928, the infants nursed on low-pressure oxygen, breast milk and a daily drop of whiskey. An article about the incubators from the August 4, 1928 Brooklyn Daily Eagle.
