The
eleven digit dial was invented by a mortician named Almon B. Strowger. He was
convinced that the local operators were diverting all the mortuary business
calls to his competitors. So, he decided to do away with operators. He was granted
a patent on March 10, 1891. And thus, the Strowger Automatic Exchange (which
later became the Automatic Electric Company then finally GTE) came into being.
This particular desk set was found in a garage in Grants Pass, Oregon by its
present owner. It is now part of the Christianson Telephone Collection.
