William Morrison (23 August 1855 – 29 August 1927) was a Scottish chemist. His background in chemistry piqued his interest in improving storage batteries. He concentrated on how to produce the most available energy for a unit of weight for efficiency in the working of an individual battery cell. Eventually, he developed storage batteries far more powerful than what had then been available. To demonstrate his batteries, Morrison installed 24 of them on a common horse-drawn carriage and attached an electric motor to the rear axle to be powered by them. Through various innovations, he developed the controls for the power used and the vehicle's steering so that the driver had complete control. Morrison invented the first practical self-powered four-wheeled electric carriage in the United States. His electric vehicle was the first to be driven in Chicago and in his hometown of Des Moines, Iowa. This electric horseless buggy of the late 19th century helped pave the way for the hybrid electric automobile of the 21st century.
