Andrew W. Mellon
Andrew Mellon was born on March 24th, 1855 in Pittsburgh, Pennsylvania, to the wealthy Mellon Family. His financial aptitude was tested early in his life as his father got him up and running in a lumber and coal business at the age of 17. His business sense and acumen led to him making the business profitable and eventually led to his joining his father's banking firm and having the business transferred to him at the age of 27.
Mellon's business interests were not limited strictly to finance, with interests stretching into the oil, steel, construction, and shipbuilding industries, as well as into aluminum, carborundum, and coke (fuel). Among others, he helped finance Charles Martin Hall, whose refinery eventually became the aluminum giant ALCOA.
Mellon's business interests segued into public service when he became Secretary of the Treasury in 1921. He served in that capacity for over 10 years, the third longest in that position. He then served as United States Ambassador to the United Kingdom for one year. During his public service Mellon argued and fought for progressive tax reform and to lower the country's large debt following World War I. Mellon led a very productive life that ended with a number of generous gifts and philanthropic endeavors.
