Peter Cooper Hewitt (May 5, 1861 – August 25, 1921) was an American electrical engineer and inventor, who invented the first mercury-vapor lamp in 1901. Hewitt was issued U.S. Patent 682,692 on September 17, 1901. In 1903, Hewitt created an improved version that possessed higher colour qualities which eventually found widespread industrial use.
Hewitt was born in New York City, the son of New York City Mayor Abram Hewitt and the grandson of industrialist Peter Cooper. He was educated at the Stevens Institute of Technology and the Columbia University School of Mines.
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.
Peter Cooper (February 12, 1791 – April 4, 1883) was an American industrialist, inventor, philanthropist, and candidate for President of the United States. He designed and built the first American steam locomotive, the Tom Thumb, and founded the Cooper Union for the Advancement of Science and Art in Manhattan, New York City.
Peter Cooper was born in New York City of Dutch, English and Huguenot descent, the fifth child of John Cooper, a Methodist hatmaker from Newburgh, New York He worked as a coachmaker's apprentice, cabinet maker, hatmaker, brewer and grocer, and was throughout a tinkerer: he developed a cloth-shearing machine which he attempted to sell, as well as an endless chain he intended to be used to pull boats on the Erie Canal, which De Witt Clinton approved of, but which Cooper was unable to sell.
In 1821 Cooper purchased a glue factory on Sunfish Pond for $2,000 in Kips Bay, where he had access to raw materials from the nearby slaughterhouses, and ran it as a successful business for many years, producing a profit of $10,000 (equivalent to roughly $200,000 today) within 2 years, developing new ways to produce glues and cements, gelatin, isinglass and other products, and becoming the city's premier provider to tanners, manufacturers of paints, and dry-goods merchants. The effluent from his successful factory eventually polluted the pond to the extent that in 1839 it had to be drained and refilled.
Peter Cooper (born 5 August 1935) is a former Australian rules footballer who played with St Kilda in the Victorian Football League (VFL).

Cooper Hewitt, Smithsonian Design Museum is a design museum located in the Upper East Side's Museum Mile in Manhattan, New York City. It is one of nineteen museums that fall under the wing of the Smithsonian Institution and is one of two Smithsonian museums located in New York City, the other being the George Gustav Heye Center in Bowling Green. It is the only museum in the United States devoted to historical and contemporary design. Its collections and exhibitions explore approximately 240 years of design aesthetic and creativity.
The Cooper Hewitt Museum was founded in 1896. It was originally named Cooper Union Museum for the Arts of Decoration and it fell under the wing of the Cooper Union for the Advancement of Science and Art. In 1895, the granddaughters of Peter Cooper, Sarah Cooper Hewitt, Eleanor Garnier Hewitt and Amy Hewitt Green, asked the Cooper Union for a space to create a Museum for the Arts of Decoration. The museum would take its inspiration from the Musée des Arts Décoratifs, Paris. The museum would serve as a place for Cooper Union students and professional designers to study decorative arts collections. Cooper Union trustees provided the fourth floor of the Foundation Building. It opened in 1897. It was free and open three days a week.
