In Feb-ruary 1903 a number of prominent citizens ofNew York set on foot a movement to raise amemorial fund of $500,000 to be presented toCooper Union as the Abram S.

ABRAM STEVENS HEWITT HEWLETT — HEYSE he invented the Cooper Hewitt lamp and staticconverter. The lamp in its present form con-sists of a glass tube of any desired shape witha bulb at one end which contains a small quan-tity of mercury. All air is exhausted from thetube, which thereupon fills with vapor fromthe mercury in the bulb. Electrodes are pro-vided at each end of the lamp, the negativeelectrode in the bulb of mercury and the posi-tive electrode at the opposite end. On passinga direct current through the lamp the vaporwhich fills the tube is rendered incandescentand gives off a steady, blue-white light. Owingto the great resistance at the negative electrodeto the initial flow of current, it is necessary touse a high voltage to start the lamp. This iscommonly done by passing a spark from achoking coil through the negative electrode,which when once penetrated offers but slightresistance to the flow of current. If for anyreason the current is interrupted, the high re-sistance is
