    Gabriel Lippmann. French physicist Gabriel Lippmann (–) is the inventor of an early process that yielded the first permanent color photograph. Though his system was too unwieldy to be used commercially at the time, Lippmann was awarded the Nobel Prize in physics for his achievement. "Rather than the antiquated photographic process for which he received the Nobel Prize, however. Theory of the Capillary Electrometer. The presence of even a trace of impurity is soont manifested by the blocking of the capillary, and if this block is removed by electrolysis, the instrument behaves for some time in an abnormal way. It shows signs of a residual charge, like that of a .

While doing research in Germany, Lippmann studied the relationship between electrical and capillary phenomenon, which led to the creation of the sensitive electrometer.

A Lippmann electrometer is a device for detecting small rushes of electric current and was invented by Gabriel Lippmann in The device consists of a tube which is thick on one end and very thin on the other.

The thin end is designed to act as a capillary tube. The tube is half-filled with mercury with a small amount of dilute sulfuric acid above the mercury in the capillary tube. THE electro-capillary machine of Lippmann and his capillary electrometer, besides the capillary electroscope of Werner Sieinens and the electro-chemical relay of Wheatstone are all illustrations.

Tucker edition. The ordinary Lippmann type of capillary electrometer consists of a single fine tube in which the rise of mercury depends upon the impressed voltage for small voltages up to one volt. The new capillary electrometer here discussed is an inverted U tube device whereby direct readings of the pressure difference between the two mercury levels can be made, thus obviating the necessity for assuming.

Gabriel Lippmann’s method for the diffractive manifestation of color were mixed with Nobel Laureate Dennis Gabor’s technique.[3] The physics behind both methods can be understood on the same principle, as the wave nature of light is used which involves encoding the image field by interference, recording the structure in a photographic plate, and then reading out the image field.

The theory of the instrument has been treated by Lippmann, Hermann, and others, mainly from a mathematical stand-point, and the phenomena have been ascribed to polarization, but no adequate attempt appears to have been made to establish by actual measurement the accuracy of the formula for the time-relations, nor to ascertain whether there were.
