Henry Black was born in Illinois ca. 1836, and lived in Carrollton, Illinois, with his parents, William and Caroline, who owned a farm. His siblings included John W., Catherine, and Alice. In 1864, he moved temporarily to Pacheco, California, where he worked on a farm, and in 1866 he returned to Carrollton and received a patent for a pulley used in hay harvesting. He spent the next several years marketing and selling his machine in the Midwest and South. He committed suicide in 1878.
