Henry Blair (1807–1860) was the second African American inventor to receive a US patent.

He was born in Glen Ross, Maryland, United States in 1807. His first invention was the Seed-Planter, patented October 14, 1834, which allowed farmers to plant more corn using less labor and in a shorter time. On August 31, 1836 he obtained a second patent for a cotton planter. This invention worked by splitting the ground with two shovel-like blades which were pulled along by a horse. A wheel-driven cylinder followed behind which dropped the seed into the newly plowed ground. Blair had been a successful farmer for years and developed the inventions as a means of increasing efficiency in farming.

In the patent records, Blair is listed as a “colored man,” making this identification the only one of its kind in early patent records. Blair was illiterate, therefore he signed his patents with an “x”. It is said that Blair was a freedman. At the time that his patents were granted, United States patent law allowed both freed and enslaved people to obtain patents. In 1857, this law was challenged by a slave-owner who claimed that he owned “all the fruits of the slave’s labor,” including his slave’s inventions. This resulted in a change of the law in 1858 which stated that slaves were not citizens, and therefore could not hold patents. Blair died in 1860. In 1871, six years after the American Civil War ended, the law was changed to grant all men patent rights.

After finding success as a farmer, Blair proved himself a capable inventor. On October 14, 1834, Blair received his patent for his mechanical corn seed planter. Blair’s corn planter resembles a wheelbarrow with a chamber fixed to the bottom that disperses the seed. After the seed is dispersed, rakes attached to the back of the wheelbarrow drag over the seed to cover them with soil. Blair’s corn planter resulted in more efficient crop planting and resulted in greater overall yield for farmers. According to an 1836 article from The Mechanics’ Magazine, Blair’s invention was conjectured to “save the labor of eight men.”

On August 31, 1836, Blair obtained a patent for his mechanical cotton planter. The device is essentially an adaptation of Blair’s corn planter optimized for cotton. The cotton planter also resembled a wheelbarrow, but it had two blades that split the earth while a cylinder located behind the blades dispersed the seeds in to the freshly ploughed grooves.

Henry Blair died in Maryland in 1860 of unknown causes.
