What they did

Blair received United States patents for a corn seed planter and a cotton planter in the 1830s, and is recorded in the Patent Office register as 'a colored man' — one of the very few such notations in the era's files.

Historical context

Planting by hand set the ceiling on how much ground a farm could work. Mechanical planters opened rows, dropped seed and covered it in one pass.

The legacy

Blair is the second African American known to this archive to have been granted a US patent. The specific document numbers fall within the X-patent series damaged in the 1836 Patent Office fire.
