H. P. & E. Day, Inc.

In 1854 Austin G., Julius, and Henry P. Day and Thomas Sault founded the A.G. Day Company in Seymour, Connecticut, which manufactured small household and office items from molded hard rubber, particularly pen and pencil holders. In the 1860s the firm began making insulated telegraph wire. In 1870 A. G. Day Company produced 100 miles of wire while another firm, Julius Day Company, took over the manufacture of small rubber goods. By 1876 the rubber company was known as H. P. & E. Day Company and run by Julius's sons Henry P. and Edmund Day. The company was incorporated in 1902 and thereafter known as H.P. & E. Day, Inc.

The company rubber works formed the basis of a new enterprise for the L.E. Waterman Pen Company of New York. Lewis Edson Waterman, pioneer of the production of hard rubber fountain pens, established the company in 1884. The principal parts of the pens were produced at H. P. & E. Day, Inc., at its Seymour plant. This arrangement continued until 1946 when H. P. & E. Day, Inc., became a wholly owned subsidiary of the Waterman Pen Company .
