Did you know that a Rochester man received the first patent for an automobile issued in the United States? According to RMSC News & Programs, Spring 2014 magazine, "Few realize Rochester's long history of invention in the auto industry. ...In 1879, patent attorney George B. Seldon of Rochester filed an application for a U.S. patent for a gas-powered Road Engine, and his submission described a complete automobile." Click here to read more.
