- Incoming Correspondence
- Outgoing Correspondence
The Langhorne brothers (Edmund, James and John) were quite involved in
the early business of the American Arithmometer Company, until a power struggle
with Joseph Boyer forced them out. They were involved in upper management when
the company was still located in St. Louis, MO (1886-1904).
Edmund G. Langhorne was appointed Secretary and General Manager of the
American Arithmometer Company about 1893-1894. He became President in 1900,
although he also kept his position as General Manager. He was forced out in
1902 and moved over to become president of the Universal Adding Machine
Company, taking almost half of the Arithmometer employees with him. (Universal
was acquired by Burroughs in 1908). Edmund moved to Pike Adding Machine Company
as president and general manager in 1905. (Pike was acquired by Burroughs in
1909). Edmund G. Langhorne also served as an attorney for American Arithmometer
beginning in 1907. He remained in this position until he left the company.
James C. (or Q.) Langhorne was designated as Director of the American
Arithmometer Company about 1889-1890, and was also the General Manager for a
short time in 1893. He resigned as Director of the company in 1895.
John T. Langhorne was appointed Assistant General Manager of American
Arithmometer Company in 1900. He left in 1902 to became General Manager of the
British Company in Nottingham. Burroughs got the English rights back in 1908.
Collection Scope and Content Note
The collection consists of correspondence to and from various members
of the Langhorne family. Most of the correspondence relates to company
business, including letters from various salesmen. The collection also includes
a large binder filled with family and business correspondence (1897-1898), and
a few sheets containing excerpts (1887, 1895, 1897) from the Langhorne
letterbook. The papers in the binder are extremely thin and fragile. About half
are written and half typed.
The Langhorne family appears to have been quite large, with letters
addressing another brother named Ned, and sisters named Jennie, Kate, Sallie,
Agnes, and Mary. A few letters appear to be from John to women he was
interested in, including Hannah, and a Miss Parrish (possibly the same person).
This is one series of the Burroughs Corporation Records (CBI 90).
