 In 1737, Banneker was named at the age of 6 on the deed of his family's farm in the Patapsco Valley in rural Baltimore County.Although a letter writer stated in 1791 that Banneker's parents had sent him to an obscure school where he learned reading, writing and arithmetic as far as double position, the remainder of Banneker's early life is not well documented.Unverified accounts that first appeared in books published more than 140 years after Banneker's death relate that, as a young teenager, Banneker met and befriended Peter Heinrich, a Quaker who later established a school near the Banneker family farm.
