Robert P. Rader pursued his studies in public and private schools of Easton, and at Nazareth Hall, Pennsylvania. He entered upon his business career as an apprentice to the machinist's trade, and after three years began working as a journeyman. Four yars were thus passed, and in 1875 he became engineer in the employ of the Lehigh Water Company, with which he has now been associated for twenty-eight years. In 1882 he was made superintendent of the plant, and has since served in that capacity. Mr. Rader is a Republican in politics, and socially, is connected with the Heptasophs.
