Alexander Stuart (1810-1879)
Stuart and his brother, Robert Leighton Stuart, made their fortune refining sugar. As employers, their popularity was never more evident than during the New York Draft Riots of 1863, when of their own free will, their workers successfully defended against the angry mob that threatened to over-run their factories. Alexander was unmarried and left his fortune to his brother, who also died without children. Their entire $5 million fortune was left to charitable causes.
