An electric light, lamp, or light bulb is an electrical component that produces light. It is the most common form of artificial lighting. Lamps usually have a base made of ceramic, metal, glass, or plastic, which secures the lamp in the socket of a light fixture, which is often called a "lamp" as well. The electrical connection to the socket may be made with a screw-thread base, two metal pins, two metal caps or a bayonet mount.
Thomas Alva Edison was an American inventor and businessman. He developed many devices in fields such as electric power generation, mass communication, sound recording, and motion pictures. These inventions, which include the phonograph, the motion picture camera, and early versions of the electric light bulb, have had a widespread impact on the modern industrialized world. He was one of the first inventors to apply the principles of organized science and teamwork to the process of invention, working with many researchers and employees. He established the first industrial research laboratory.
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament that is heated until it glows. The filament is enclosed in a glass bulb that is either evacuated or filled with inert gas to protect the filament from oxidation. Current is supplied to the filament by terminals or wires embedded in the glass. A bulb socket provides mechanical support and electrical connections.
The National Electric Light Association (NELA) was a national United States trade association that included the operators of electric central power generation stations, electrical supply companies, electrical engineers, scientists, educational institutions and interested individuals. Founded in 1885 by George S. Bowen, Franklin S. Terry and Charles A. Brown, it represented the interests of private companies involved in the fledgling electric power industry that included companies like General Electric, Westinghouse and most of the country's electric companies. The NELA played a dominant role in promoting the interests and expansion of the U.S. commercial electric industry. The association's conventions became a major clearinghouse for technical papers covering the entire field of electricity and its development, with a special focus on the components needed for centralized power stations or power plants. In 1895 the association sponsored a conference that led to the issue of the first edition of the U.S. National Electrical Code. Its rapid growth mirrored the development of electricity in the U.S. that included regional and statewide affiliations across the country and Canada. It was the forerunner of the Edison Electric Institute. Its highly aggressive battle against municipal ownership of electric production led to extensive federal hearings between 1928 and 1935 that led to its demise. Its logo is an early depiction of Ohm's law which is "C equals E divided by R," or "the current strength in any circuit is equal to the electromotive force divided by the resistance," or the basic law of electricity. It was established in 1827 by Dr. G. S. Ohm.
This Side of Paradise is the debut novel by American writer F. Scott Fitzgerald, published in 1920. It examines the lives and morality of carefree American youth at the dawn of the Jazz Age. Its protagonist, Amory Blaine, is an attractive middle-class student at Princeton University who dabbles in literature and engages in a series of romances with flappers. The novel explores the theme of love warped by greed and status-seeking, and takes its title from a line of Rupert Brooke's poem Tiare Tahiti.
The Rocky Mountain Institute, commonly abbreviated to RMI, is an organization in the United States co-founded by Amory Lovins dedicated to research, publication, consulting, and lecturing in the field of sustainability, with a focus on profitable innovations for energy and resource efficiency. RMI was established in 1982 and has grown into a broad-based institution with over 600 staff and an annual budget of $120+ million. RMI's work is independent and non-adversarial, with an emphasis on market-based solutions.
Christmas lights are lights often used for decoration in celebration of Christmas, often on display throughout the Christmas season including Advent and Christmastide. The custom goes back to when Christmas trees were decorated with candles, which symbolized Christ being the light of the world. The Christmas trees were brought by Christians into their homes in early modern Germany.
Daniel McFarlan Moore was a U.S. electrical engineer and inventor. He developed a novel light source, the "Moore lamp", and a business that produced them in the early 1900s. The Moore lamp was the first commercially viable light-source based on gas discharges instead of incandescence; it was the predecessor to contemporary neon lighting and fluorescent lighting. In his later career Moore developed a miniature neon lamp that was extensively used in electronic displays, as well as vacuum tubes that were used in early television systems.
Ben Hur is a 1907 American silent drama film set in ancient Rome, the first screen adaptation of Lew Wallace's popular 1880 novel Ben-Hur: A Tale of the Christ. Co-directed by Sidney Olcott and Frank Oakes Rose, this "photoplay" was produced by the Kalem Company of New York City, and its scenes, including the climactic chariot race, were filmed in the city's borough of Brooklyn.
Neon lighting consists of brightly glowing, electrified glass tubes or bulbs that contain rarefied neon or other gases. Neon lights are a type of cold cathode gas-discharge light. A neon tube is a sealed glass tube with a metal electrode at each end, filled with one of a number of gases at low pressure. A high potential of several thousand volts applied to the electrodes ionizes the gas in the tube, causing it to emit colored light. The color of the light depends on the gas in the tube. Neon lights were named for neon, a noble gas which gives off a popular orange light, but other gases and chemicals are used to produce other colors, such as hydrogen (purple-red), helium, carbon dioxide (white), and mercury (blue). Neon tubes can be fabricated in curving artistic shapes, to form letters or pictures. They are mainly used to make dramatic, multicolored glowing signage for advertising, called neon signs, which were popular from the 1920s to 1960s and again in the 1980s.
Baker Motor Vehicle Company was an American manufacturer of Brass Era electric automobiles in Cleveland, Ohio, from 1899 to 1914.
The Knickerbocker Theatre, previously known as Abbey's Theatre and Henry Abbey's Theatre, was a Broadway theatre located at 1396 Broadway in New York City. It operated from 1893 to 1930. In 1906, the theatre introduced the first moving electrical sign on Broadway to advertise its productions.

Schuyler Skaats Wheeler was an American electrical engineer and manufacturer who invented the electric fan, an electric elevator design, and the electric fire engine. He is associated with the early development of the electric motor industry, especially to do with training the blind in this industry for gainful employment. He helped develop and implement a code of ethics for electrical engineers and was associated with the electrical field in one way or another for over thirty years.
Walter D'Arcy Ryan was an influential early lighting engineer who worked for General Electric as director of its Illuminating Engineering Laboratory. He pioneered skyscraper illumination, designed the Scintillator colored searchlights display, and was responsible for the lighting of the Panama–Pacific International Exposition in San Francisco and the Century of Progress Exposition in Chicago, in addition to the first complete illumination of Niagara Falls. He combined illumination into both an art and a science.
William Joseph Hammer was an American pioneer electrical engineer, aviator, and president of the Edison Pioneers.
An electric fire engine is a fire engine that is powered by an electric motor—essentially, an electric vehicle designed and used for firefighting. Electric fire engines were first proposed in the 19th century to replace the steam pumpers used for firefighting. The electric motor was claimed to be simpler, cleaner, and faster in operation, would save money, and require less maintenance than the steam fire engine. Though production of most electric-powered fire engines ended in the early 20th century when they were superseded by diesel-powered fire engines, they have seen a revival in the 21st century, with fire engine manufacturers such as Rosenbauer and Pierce Manufacturing designing their own electric fire engines.
Thamara de Swirsky, sometimes seen as Tamara de Svirsky, Thamara Swirskaya, or Countess de Swirsky, was a Russian-born dancer, known for dancing barefoot.
Benjamin Moses Teal was an American actor, theater director, and playwright. He directed over 30 plays on Broadway between 1897 and 1916, and was widely known for his strict, often brusque stage direction. Born in Eugene, Oregon, Teal spent his formative years in San Francisco, where he began performing as a child actor in theatrical productions.
The Hotel Normandie was a luxury hotel located on Broadway at 38th Street in New York City. The 8-story building was put up by Ferdinand Earl, an heir of the Fisher family, opening in 1884. Amenities were advertised to include "Steam heat, speaking tubes, electric bells, burglar and fire alarms attached to all rooms". Rooms rates started at $2/day. Dinner was available for $1.25 additional; a quart bottle of Moët & Chandon champagne was $4.
