We all know Andrew Carnegie as a philanthropist, industrialist, and robber baron. At the early age of 16, Carnegie joined the Pittsburgh telegraph office and became Thomas Scott’s private secretary and telegrapher. Later on, Carnegie joined Thomas Scott at the Pennsylvania Railroad, where he became general superintendent. Their relationship continued and, Carnegie learned, prospered, and worked out of poverty.
