The Watertown Arsenal operated continuously as a military munitions and research facility from 1816 until 1995, when the Army sold the property, by then known as the Army Materials Technology Laboratory, to the town of Watertown. The Arsenal is notable for being the site of a 1911 strike prompted by the management methods of operations research pioneer Frederick Winslow Taylor (Taylor and 1911 Watertown Arsenal Strike). Taylor's method, which he dubbed "Scientific Management," broke tasks down into smaller components. Workers no longer completed whole items; instead, they were timed using stopwatches as they did small tasks repetitively, as Taylor attempted to find the balance of tasks that resulted in the maximum output from workers. The strike and its causes were controversial enough that they resulted in Congressional hearings in 1911; Congress passed a law in 1915 banning the method in government owned arsenals. Taylor's methods spread widely, influencing such industrialists as Henry Ford, and the idea is one of the underlying inspirations of the factory (assembly) line industrial method. The Watertown Arsenal was the site of a major superfund clean-up in the 1990s, and has now become a center for shopping, dining and the arts, with the opening of several restaurants and a new theatre. The site includes the Arsenal Center for the Arts, a regional arts center that opened in 2005. The Arsenal is now owned by athenahealth. Arsenal Street features two shopping malls across the street from one another, with the Watertown Mall on one side and Arsenal Yards on the other.
