About the author
Born in Campton, New Hampshire, in 1803, Sylvester Marsh became an American merchant and inventor whose name is closely tied to the Mount Washington Cog Railway. Before that achievement, he worked in business and industry, building a reputation as an energetic and capable entrepreneur.
Marsh is remembered most for designing and building the railway up Mount Washington, using a rack-and-pinion system that allowed trains to climb slopes too steep for ordinary railroads. The project was unusual enough that many people doubted it would work, but the line opened in the late 1860s and became one of the great engineering landmarks of New Hampshire.
He died in Concord, New Hampshire, in 1884. What keeps his legacy alive is not just the invention itself, but the determination behind it: he saw a difficult problem, imagined a new solution, and followed it through until it was real.
