Clement Stewart, son of John and Elizabeth (Green) Stewart, was born in Easton, Pennsylvania, November 25, 1842. He acquired his early education in the private schools conducted by Dr. Lehman and the Rev. Dr. McPhail, and also studied under Professors Edsall Ferrict and R. B. Youngman, of Lafayette College. He was so well prepared that upon matriculation at Princeton he entered the sophomore class in 1862, and was graduated A.B., class of 1864. Following graduation he entered the employ of Stewart & Company, manufacturers of wire, his father, John Stewart, being the capable head of that firm. The young man began at the bottom, but rose to the position of assistant superintendent after mastering the work of several departments of the business. He continued as assistant superintendent until 1892, when he resigned after twenty-eight years of active connection with Stewart & Company, during which time he gave to the business his energy and devotion. In 1889, Mr. Stewart was appointed assistant postmaster of Easton, and for seventeen years he held that position. Mr. Stewart, in 1863, enlisted in Company D. Thirty-eighth Regiment, Pennsylvania, known as the "Iron Regiment," recruited when Pennsylvania was invaded by the Confederates. The regiment was mustered into the service in June 1863, and honorably discharged August 7, 1863. He was for years a member of McKeen Post, Grand Army of the Republic, but later transferred to the staff of the national commander of the Grand Army of the Republic, for one year with the rank of colonel; was adjutant of McKeen Post six years, and officer of the day two years. In politics a Republican, he has always been actively interested in party success, and has served as a member of the School Board and Easton Town Council. Through his patriotic ancestry he gained admission to the Pennsylvania Society, Sons of the Revolution, and is a member of the American Institute of Mining Engineers, Dallas Lodge, Free and Accepted Masons of Easton, the McKinley Club, Cliosophic Society of Princeton, and to the Greek letter fraternity, Zeta Psi.
