The Nothomb Lamp
The William J. Hammer historical collection of incandescent electric lamps, which is now stored in the Henry Ford Museum in Dearborn, Michigan, contains several lamp designs that were developed in countries other than the United States. One of these was known as the Nothomb lamp. In the chronological listing of Hammer lamps it can be seen2 that the collection has an 1881 as well as an 1882 lamp2. The information that Hammer printed on placards that accompanied the lamps when on display read as follows2:

1881-12, Nothomb (French). Low resistance filament, carbon paste clamps, platinum hook supports, blue tip bulb.
1882-487, Nothomb (French). Small bulb and filament with carbon paste clamps. Made in France.

A short article appeared in 18831 that gave some details of this lamp. The information in the article came from the London Electrical Review. In part, it said:

"This incandescent lamp is distinguished from its predecessors by the nature of the incandescent filament and the mode of manufacture. The filament consists of cellulose carbonized in a carbureted atmosphere which impregnates it with carbon. It is one millimetre wide and 4/10ths of a millimetre thick; its length depends on the luminous intensity required. The atmosphere of the globe of glass in which it is inclosed consists of azote, hydrogen, or any other inert gas.

"The filament is fixed to conductors by means of a special kind of cement, composed of a mixture of spongy platinum and an organic substance, molasses or sugar, which on carbonizing forms carbon of very close texture and great consistency. The duration of the lamp, according to the experiments made, should be from 800 to 1,000 hours; the luminous power 30, 50 or 100 candles..."

There were four lamp types with currents of one to three amperes and voltages of 45 to 100 volts. One type, of 300 candles, had three filaments and they could be connected in series or parallel. In one case the current drawn was nine amperes at 100 volts. In the other case it drew three amperes at 300 volts. The horseshoe shape of the filament was adopted even though better results were obtained with a spiral filament.
