Isaiah Vansant Williamson  Isaiah Vansant Williamson (February 4, 1803 – March 7, 1889), commonly known as I. V. Williamson, was an American merchant and philanthropist from Pennsylvania. Williamson was born in Bensalem Township, Pennsylvania on February 4, 1803 to Mahlon and Charity (Vansant) Williamson and in 1807 moved with his family to Fallsington. There he attended the Friends' School and worked on his family's farm. He became apprenticed to Harvey Gillingham at Gillingham Store in the center of Fallsington for six or seven years. In this position, he traveled to the surrounding communities and Philadelphia, where he learned the trade of buying and selling various goods. In 1825, he moved to Philadelphia and got a position as a salesman there. Saving and investing his earnings, he eventually became partner in Williamson, Burroughs & Co. selling dry-goods to local shops, where he made a large amount of his fortune. Williamson was known for his philanthropy, though due to the way he dressed and walked through the city, he was sometimes referred to as the "threadbare philanthropist." Also, it has been difficult to determine how much Williamson gave because most of his donations were made anonymously under the pseudonym “Hez.” His large sums of money went to hospitals, including the Hospital of the University of Pennsylvania in the 1870s and founding the Williamson Free School of Mechanical Trades with $5,000,000, December 1, 1888, a gift "larger than the entire endowment of Harvard, Yale or Columbia." Isaiah V. Williamson died in Philadelphia on March 7, 1889 due to aortic valvular disease.
