Electric Lighting
History
Many teams and individuals have been involved with electric lighting
technology during the past 120 years. Their collective efforts turned
the marvel of electric lighting into a mundane part of our technical
infrastructureand in the process changed the way we live.
This section (to be expanded in future updates) presents some details
of the history they have shaped.
Advertising: Ink Blotters
Light bulb makers have tried many methods of advertising their
products. A common technique involved giving consumers (or retailers)
a low-cost, useful item imprinted with an advertisement. In 1998
General Electric donated to the museum an archival collection that
included an assortment of 38 ink blotters dating from early in the
20th century. Made of cardboard and measuring about 15.25 x 7.5
cm (6 x 3 inches), these blotters could be printed with the name
of the participating store or electric utility.
Eighteen of the blotters are presented below. Click on any of the
images for an enlarged view and additional information about that
blotter. The General Electric Nela Park
material is collection number 0789 in the museum's Archives Center. Researchers may view this material by making
an appointment with the Archives
Center.
