1.0 INTRODUCTION
Founded by engineer George M. Pfundt in 1936, GMP started operations in a downtown Philadelphia building as a specialty machine shop doing work for the local Bell Telephone company and
for the electric utility company. GMP expanded to a production
shop after landing a contract
with Western Electric Company and, subsequently, forming a close relationship
with Bell Telephone Laboratories in Murray Hill,
N.J., which enabled it to manufacture prototypes
of products for experimental use within the Bell
System.
Having outgrown the original factory building, the
company built a 100,000 square foot plant in Trevose, PA (a Philadelphia suburb) and moved there
in 1957. Today GMP is recognized as a premier
worldwide supplier of specialty tools and equipment for the outside plant marketplace.
The company's products are known for their robust design and durability to withstand
many years of frequent use.
