Autographed photograph handwritten letter envelope America John Frank Stevens (born April 25, 1853; died June 2, 1943) was an American engineer who built the Great Northern Railway in the United States. In 1889, he was hired by James J. Hill as a locating engineer for the Great Northern Railway. He was the first European American to discover the Marias Pass over the Continental Divide. During his time at the Great Northern, Stevens built over a thousand miles of railroad, including the original Cascade Tunnel. In 1905, he was hired by Theodore Roosevelt as chief engineer on the Panama Canal. Stevens' primary achievement was to build the infrastructure needed for the completion of the canal. The digging, he said, is the least thing of all. He proceeded immediately to build warehouses, machine shops, and piers. Communities for the personnel were planned and built to include housing, schools, hospitals, churches, and hotels. He authorized extensive sanitation and mosquito-control programs that eliminated Yellow Fever and other diseases from the Isthmus. Reflecting his background, he saw the early stage of the canal project itself as primarily a problem in railroad engineering, which included rebuilding the Panama Railway and devising a rail-based system for disposing of the soil from the excavations. Stevens resigned suddenly from the Canal project in 1907, to Roosevelt's great annoyance, as the focus of the work turned to construction of the canal itself. As a railroad engineer, Stevens had little expertise in building locks and dams, and may have realized he was no longer the best person for the remainder of the job. Stevens would also have been aware that the original great Cascade Tunnel, for which he was responsible, was in hindsight built in error too close to the ruling grade and was perhaps turning from a credit to a debit. The true reasons for his resignation have never been known. Following the collapse of Imperial Russia in 1917, Stevens was selected to chair a board of prominent U.S. railroad experts sent to Russia to rationalize and manage a system that was in disarray; among his work was on the Trans-Siberian Railway. He was awarded the Franklin Institute's Franklin Medal in 1930. He then retired to Southern Pines, North Carolina, where he died at the age of 90 in 1943.
