History
Lockwood, Greene & Company
The firm that would become Lockwood, Greene & Company was established in 1871 in Boston as the mechanical engineering practice of Amos D. Lockwood. Lockwood, a native of Rhode Island, was self-trained in mechanical engineering and had extensive experience managing textile manufacturing and construction operations. Extenuating circumstances obligated him to move his residence to Providence in 1873 to manage his manufacturing interests.
His office remained in Boston until 1875, when he relocated it to Providence, where he established A. D. Lockwood & Company to manage all of his business interests. His partner was John W. Danielson, his son-in-law, who had at least fifteen years of similar experience. In 1879 Lockwood hired the engineer Stephen Greene, formerly associated with civil engineers Niles B. Schubarth and David M. Thompson. March 1, 1882, a new partnership was organized between Lockwood, Danielson and Greene, known as Lockwood, Greene & Company. Lockwood died January 16, 1884, in Providence.
