Friends Board member Laura Compagni-Sabella gave a terrific tour of the Croton Dam on Saturday September 6th, complete with pictures and samples of tools used by workers on the Croton Dam. To many people, the New Croton Dam in Croton-on-Hudson, NY, represents the ingenuity of American engineers of the late nineteenth century. At completion, it stood as the tallest masonry dam in the world. People compared it to the pyramids and to the Great Wall of China as a testament to human genius. The Dam is also a central feature in a dramatic labor story.
