Born in Montgomery County, Maryland, and living and working at a time and place hostile to people of African American descent, Henry Blair is the only inventor described as “a colored man” in the records of the U.S. Patent Office. His corn seed planter, patented on October, 14, 1834, allowed farmers to plant more corn in a shorter period of time. The corn planter, which was pulled by horses or oxen, dropped individual kernels of corn into furrows, which were then automatically covered with earth as a farmer walked behind the planter. Blair’s cotton planter, patented two years later in 1836, was equally instrumental to the agricultural revolution that began in the United States during the first half of the nineteenth century.
