Known as Boston Harbor Shipyard & Marina today, the company was founded in 1839. The shipyard is located in East Boston, Massachusetts. It was established just six years after the city began to be developed as a neighborhood. Samuel Hall is the founder of East Boston Shipyard. Shortly after it was established, the business grew to include dry docks using the most innovative technology and marine railways, which are still visible today along the waterfront. However, the shipyard exposed workers to great levels of asbestos, a dangerous mineral that can lead to cancer. Employees would inevitably breathe in toxic asbestos fibers by handling asbestos products such as insulation, floor tiles, gaskets, and boilers without protective gear.
