Wilson Osco

Wilson Rudolph Osco III (January 20, 1849 - October 12, 1926) was an American investor, banker, and financier who was a central figure in the industrial era of the United States. At his height in the early 20th century he controlled investments and securities of the largest corporations of every major industry of the time, from electronics to mining, and was worth an estimated 13 billion dollars. His partnerships with scientific minds such as James Robertson, J.F. Daniels, and Edmond Dowd helped to create new fields of industry. Many businesses, including United Telephony, National Paper & Print, Eltringham, Tritian, Robertson Electric Company, and XZG trace their origins to his financial construction, and many others flourished under his investments.
