For $1700, Nathan Platt bought the original site of the Platt Brothers Plant, including 30 acres of land, water rights, a sawmill, a gristmill, a barn and a house.
The Platts were producing wire and button eyes, which then led to the manufacture of ferrous and non-ferrous buttons.
Nathan’s son Alfred continued his father’s ambitions by establishing a small button-making and metal working business alongside his father’s.

The Platt Brothers & Company was officially incorporated in 1876. The company was formed from an earlier partnership of Alfred Platt and his two sons called, “A. Platt & Sons”, which had been functioning since 1847.
On Friday, August 19, 1955 the Naugatuck river floods, destroying most of Platt’s buildings and nearly destroying the company. At a director’s meeting and against the advice of some stockholders who want to liquidate, Horton Camp Sr. and Howard Hart recommend rebuilding.
