The Story of the American Inventor Denied a Patent Because He Was a Slave
"The world of invention is famous for its patent disputes. But what happens when your dispute wasn’t with another inventor but whether the Patent Office saw you as a person at all? In 1864, a black man named Benjamin T. Montgomery tried to patent his new propeller for steamboats. The Patent Office said that he wasn’t allowed to patent his invention. All because he was enslaved."
