516 Walnut Street Do you know this Catasauqua history, about "The Million Dollar Town" and the Davies & Thomas Foundry? 516 Walnut St, originally known as 510 Walnut St, was built around 1895, and potentially a few years prior, as it was said that famous Inventor, Thomas Alva Edison stayed at the home during the summer that the Catasauqua Electric Light & Power Company installed the town's first electric street lights.
