First merchant of Easton, Pa.; his original name was "Myer Hart de Shira." He went to America at an early age, and at once engaged in trade. He is classed among the founders of Easton (1750), and was the first shopkeeper there; his name occurs in a list (1752) of the eleven original families of Easton. From the tax-lists of Northampton county it is evident that he was one of its richest merchants. On April 3, 1764, Myer Hart took the oath of allegiance to the colonial government. During the Revolutionary war he was the agent at Easton of David Franks, for the "care of Prisoners in the British Service"; on March 19, 1778, he refuted a charge of cruelty and insult to the prisoners. In August, 1779, he petitioned the "Supreme Executive Council" in regard to the removal of a tenant. About 1782 he must have removed to Philadelphia, for in that year his name occurs among the original members of the Mickvé Israel congregation; in 1785 it occurs in the first Philadelphia directory. In September, 1786, owing to failure in business his estate was sold by the sheriff. The exact date of his death is unknown, although it has been stated that he lived to near the close of the century. He married a daughter of Abraham and Esther de Leon, and had issue.

Myer was one of the founders of Easton, Pennsylvania, according to Stern, FAJF, 3rd ed., p. 103.
