Biography
Andrew Onderdonk was a builder in the epic, 19th-century mold, a man who took on projects where geography was the primary adversary. A graduate of Rensselaer Polytechnic Institute, he cut his teeth on demanding construction work before landing the contract for a defining challenge: building the San Francisco seawall, a massive undertaking that tamed the city's chaotic shoreline and created the foundation for its iconic Embarcadero. His reputation for tackling the impossible led to an even greater test in the 1880s. Hired by the Canadian Pacific Railway, he was responsible for the most difficult section of the transcontinental line through the canyons and mountains of British Columbia's Fraser Valley and the treacherous Thompson River canyon. Using thousands of workers, including many Chinese immigrants, and battling landslides, rock faces, and brutal weather, Onderdonk's crews laid track that physically united a nation. His work was a raw demonstration of industrial will against nature.
