MARSHALL, Christopher, patriot, born in Dublin, Ireland, 6 November, 1709; died in Philadelphia, Pennsylvania, 4 May, 1797. He received a classical education in England and came to this country without the permission of his parents, in consequence of which he was disowned. He settled in Philadelphia and became a chemist and pharmacist. His firm furnished most of the drugs and medicines to the troops of the " Jerseys, Pennsylvanias, and Delawares." His attachment to the American cause brought him into many posts of honor during the Revolution, and he was on confidential terms with the chief members of the Continental congress and the new government of Pennsylvania. He was disowned by the Society of Friends for the active part that he took on the patriot side. On 17 March, 1775, he was elected one of the twelve managers of a company " set on foot for making woollens, linens, and cotton," the election being held at Carpenter's hall. He was a member of the committee that met at the state-house, 25 April, 1775, to consider the measures to be pursued in the " critical affairs of America," and of the committee of safety from its first formation until the close of the war. His " Remembrancer" is one of the most valuable diaries that was kept during the Revolution. The manuscript was presented to the Pennsylvania historical society by his great-great-grandson, Charles Marshall, of Germantown, edited by William Duane and published (Philadelphia, 1839).--His son, Charles, pharmacist, born in Philadelphia, 8 May, 1744: died there, 22 August, 1825, received a classical education, entered into partner, ship with his father and elder brother, Christopher, and on their retirement from the business became sole proprietor. Early in the 19th century he retired from active business. When the University of Pennsylvania assumed to issue diplomas to practitioners of pharmacy and to prescribe the conditions of the grant, the pharmaceutists of Philadelphia felt it to be an infraction of their rights, and established in 1824 a college of pharmacy, of which Mr. Marshall, then one of the most noted men in pharmacy in America, was chosen first president.
