In 1902, the United Shoe Machinery Corporation built a quarter-mile stretch of factory buildings in Beverly. The stretch was an early landmark example of reinforced concrete construction, devised by concrete pioneer Ernest L. Ransome. In 1906 it went into production. Closed in 1987, the complex was bought by Cummings Properties in 1996, and developed into a campus of hi-tech companies and medical offices. Parker Brothers, makers of "Monopoly" and other games, has offices in Beverly. The city is also home to the Landmark School, known worldwide for the education it provides for students with learning disabilities.
