Roswell Gardinier Benedict

Roswell Gardinier Benedict (9 December 1815 – 5 February 1859) was a civil engineer by profession and became involved in land development and the manufacturing of rolling stock for railways.

Benedict's professional career was mainly spent in railway construction although his first significant project involved construction on the Welland Canal. He formed an association there with a contractor, Samuel Zimmerman, which would continue until Zimmerman's death in 1857.

Benedict had acquired extensive railway-building experience in the United States before coming to Canada. After his time on the Canal project, he became assistant to the chief engineer of the Great Western Railroad in 1847 and then chief engineer four years later.
