Biographical Note

Edwin Harrison McHenry was born on January 25, 1859 in Cincinnati, Ohio. He worked as Chief Engineer for the Northern Pacific Railway until 1901, when he went to China as an engineering advisor to the government. Returning home in 1902, McHenry went to work for the Canadian Pacific Railway. He became vice president of the New York, New Haven, & Hartford Railroad, the Boston & Maine Railroad, and the Maine Railroad in 1904.
