Marshall Jewell (October 20, 1825 – February 10, 1883) was a manufacturer, pioneer telegrapher, telephone entrepreneur, world traveler, and political figure who served as 44th and 46th Governor of Connecticut, the U.S. Minister to Russia, the 25th United States Postmaster General, and Republican Party National Chairman. Jewell, distinguished for his fine "china" skin, grey eyes, and white eyebrows, was popularly known as the "Porcelain Man". As Postmaster General, Jewell made reforms and was intent on cleaning up the Postal Service from internal corruption and profiteering. Postmaster Jewell aided Secretary of the Treasury Benjamin H. Bristow shut down and prosecute the Whiskey Ring. President Grant, however, became suspicious of Jewell's loyalty after Jewell fired a Boston postmaster over non payment of a surety bond and asked for his resignation.
