Ambulance service was established at the MGH in 1873 “for the conveyance of cases of accident, or urgent sudden sickness, not contagious, to the Hospital.” The early horse-drawn ambulances were eventually replaced by motor vehicles using electricity, steam and then gasoline. Above is the 1908 MGH ambulance, a White Steamer. Below, a Packard purchased in 1912, with Percy B. Gamble, eventual chief of the ambulance drivers, at the wheel.
