Henry Varnum Poor

From Wikipedia, the free encyclopedia

Henry Varnum Poor was a 19th century American financier and founder of H.V. and H.W. Poor Co, which was later to become Standard & Poor's.

Standard & Poor's traces its history back to 1860, with the publication of History of Railroads and Canals in the United States. This book was an attempt to compile comprehensive information about the financial and operational state of U.S. railroad companies. Henry Varnum went on to establish H.V. and H.W. Poor Co with his son, Henry William, and published updated versions of this book on an annual basis.
