The earliest ambulances were horse-drawn, first used on battlefields to carry wounded soldiers to safety and treatment. The first motorized ambulance was introduced in Chicago in 1899, donated by five hundred local businessmen. The three-wheeled Pallister ambulance, introduced in 1905, was the first to be powered by gasoline. Some years later, James Cunningham developed the first mass-produced ambulance, wich used a gong instead of the modern-day sirens.
