Judge Thomas Mellon was, at heart, a businessman, and had low tolerance for the high-falutin' oratory of many of his colleagues. While keeping a practice and serving on the bench, he found ways to advance his fortune, and retired from the law at age 57 to start a banking house with his sons. He had his greatest impact as an investor -- in steel, railways, public utilities, electricity and oil. He was a role model for the business savvy lawyers of the next generation.
