Who invented the electric streetcar?

In 1874, New York City installed an electric streetcar system designed by Stephen Dudley Field. The system was dangerous and ineffective, but it was a sign of things to come.

Eugene Cowles got the first patent for an electric trolley in the United States in 1881.

Dr. Werner von Siemens first ran an electric trolleybus, the Elektromote, near Berlin, Germany, on April 29, 1882.

Dr. Joseph R. Finney operated an experimental trolley car near Pittsburgh, PA in the summer of 1882.

John Joseph Wright invented an electric streetcar in Canada in 1883.

In 1885, John C. Henry set up the first overhead-wire electric transit system in Kansas City, MO, the first regular service in the United States.

Charles van Depoele set up trolley lines in several North American cities by 1887.

In 1888, a trolley system designed by Frank Sprague began operating in Richmond, Virginia. Sprague's system became the model for electric street railways all over the US.

In 1893, Elbert R Robinson, an African American inventor, received a patent for an electric railway trolley.

Hard to say as the "Trolley car" came out in various styles, some horse drawn, in various parts of the world, so it is hard to pin point exact time and sole inventor (If there was one) for the trolley car.

Well alot of people invented it but mostly it was John Joseph Wright
