Biography Timeline

1901

In 1901 he invented and patented a mercury-vapor lamp; a gas-discharge lamp that used mercury vapor produced by passing current through liquid mercury. His first lamps had to be started by tilting the tube to make contact between the two electrodes and the liquid mercury; later he developed the inductive electrical ballast to start the tube. The efficiency was much higher than that of incandescent lamps, but the emitted light was of a bluish-green unpleasant color, which limited its practical use to specific professional areas, like photography, where the color was not an issue at a time where films were black and white. For space lighting use, the lamp was frequently augmented by a standard incandescent lamp. The two together provided a more acceptable color. Later. in the 1930s. a fluorescent coating (phosphor) was added to the inside of the tube at General Electric, which produced more pleasing white light when it absorbed the ultraviolet light from the mercury. This was the fluorescent lamp, which is now one of the most widely used lamps in the world.

1902

In 1902 Hewitt developed the mercury arc rectifier, the first rectifier that could convert alternating current power to direct current without mechanical means. It was widely used in electric railways, industry, electroplating, and high-voltage direct current (HVDC) power transmission. Although it was largely replaced by power semiconductor devices in the 1970s and 1980s, it is still used in some high power applications. In 1903, the degree of Honorary Doctorate of Science was conferred upon him by the Columbia University in recognition of his work.

1907

In 1907 he developed and tested an early hydrofoil. In 1916, Hewitt joined Elmer Sperry to develop the Hewitt-Sperry Automatic Airplane, one of the first successful precursors of the cruise missile.
