Henry Blair (1807–1860) was the second African American inventor to receive a 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 in a smaller amount of 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 not known if Blair was a freedman or not. 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 the change of the law in 1858 which stated that slaves were not citizens and therefore could not hold patents. After the American Civil War, in 1871, the law was changed to grant all men (but not women) patent rights. He died in 1860.
