Starting in 1853, when Carnegie was around 18 years old, Thomas A. Scott of the Pennsylvania Railroad Company employed him as a secretary/telegraph operator at a salary of $4.00 per week ($ by inflation). Carnegie accepted the job with the railroad as he saw more prospects for career growth and experience there than with the telegraph company. At age 24, Scott asked Carnegie if he could handle being superintendent of the Western Division of the Pennsylvania Railroad. On December 1, 1859, Carnegie officially became superintendent of the Western Division. Carnegie then hired his sixteen-year-old brother, Tom, to be his personal secretary and telegraph operator. Not only did Carnegie hire his brother, but he also hired his cousin, Maria Hogan, who became the first female telegraph operator in the country. As superintendent Carnegie made a salary of fifteen hundred dollars a year ($ by inflation). His employment by the Pennsylvania Railroad Company would be vital to his later success. The railroads were the first big businesses in America, and the Pennsylvania was one of the largest of them all. Carnegie learned much about management and cost control during these years, and from Scott in particular.
