Biography
Andrew Onderdonk built the San Francisco seawall, a massive project that tamed the city's chaotic shoreline and created the foundation for the Embarcadero. A graduate of Rensselaer Polytechnic Institute, he then tackled the most difficult section of the Canadian Pacific Railway in the 1880s. His crews laid track 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, they battled landslides, rock faces, and brutal weather. The line physically united a nation. Onderdonk died in 1905.
