Daniel Butterfield
Butterfield was born on October 31, 1831 in Utica, New York. He attended Union Academy and then graduated in 1849, from Union College in Schenectady, New York, where he became a member of the Sigma Phi Society. That same year, his father, John Warren Butterfield, founded the express company of Butterfield, Wasson, and Co., which later became the American Express Company. After graduating, Daniel studied law but as he was too young to sit the New York bar exam, he toured the country instead. Upon his return to Utica, he joined the Utica Citizen’s Corps as a private. He was employed in various businesses in New York and the South, including the American Express Company, which had been co-founded by his father, an owner of the Overland Mail Company, stage-coaches, steamships and telegraph lines.
