Who made the first automobile in America?

There's no single definitive answer to who made the *first* automobile in America, as it depends on how you define "automobile" and what constitutes "first." Several inventors were experimenting with self-propelled vehicles around the same time. However, Duryea brothers, Charles and Frank, are generally credited with building and successfully operating the first commercially successful gasoline-powered automobile in the United States. Their car ran in 1893.
