Edward G. Zubler, a General Electric Co. research
chemist who developed the halogen lamp in 1959,
has died at the age of 79.
Zublers heart stopped while he was recovering
from surgery for a herniated disc, according to
his daughter, Rena Flovin. His heart was restarted
but he was found to be brain dead, she said.
Zubler began experimenting with halogen lighting
technology when he joined the companys
lighting research laboratory in 1953.
I was assigned to the project and told
see whats going on, see whats
making it work or not work, Zubler
told the Smithsonian Institution, which lists
his work among 20th century inventions. Frederick
Mosby later joined Zubler on the halogen project.
By adding a halogen gas, Zubler improved on standard
incandescent bulbs, which include a filament made
of a chemical called tungsten. In an incandescent
light bulb, chemical reactions with the tungsten
caused deposits to form inside and affected how
much light could shine through.
Halogen eliminated the particles, recycled the
tungsten deposits and made for a longer-lasting
light bulb.
Halogen lamps continue to be used for automobile
headlights, floodlights and stage and studio lighting.
Zubler earned numerous patents and awards for
his work in advancing lighting technology. GE
honored him in 1973 for his contributions to the
science and technology of halogen lamps.
