The Inventor of the Mercury Lamp: Peter Cooper Hewitt

- વિશ્વના વૈજ્ઞાનિઓ

After Thomas Alva Edison invented the electric bulb, many new research projects began to find better ways to get light from electricity. Edison’s bulb gave a dim yellow light, became very hot, and often fused (burnt out). To solve these problems, scientists worked to create brighter and more durable bulbs and tube lights. The Mercury Lamp is a significant invention in this field, and its creator, Peter Cooper Hewitt, holds a leading position.

Hewitt was born on May 5, 1861, into a wealthy family in New York. His family was famous in the field of engineering; his grandfather, Cooper, was a major American industrialist. Peter inherited his knowledge of engineering and science. Even as a child, he was interested in engineering and made various mechanical toys. Since his father was the Mayor of New York, he received an excellent education, eventually studying at the Stevens Institute and the Columbia University School of Mines.

In 1901, he created a bulb filled with mercury vapor. It produced a white light. He also made bulbs that worked on both AC and DC current. Beyond just standard lighting, Peter created bulbs useful for photography, railways, and industries. Using semiconductor devices that could handle high electrical currents, he made revolutionary discoveries in the field of lighting. He received many honors for his contributions to science and passed away in Paris on August 25, 1921.
