| A press photo of Thomas Alva Edison (1847-1931) features the incandescent lamps he developed at his Menlo Park laboratory in New Jersey. Although Edison did not originate the concept of the incandescent lamp, his invention of a one-piece carbon filament that glowed within a vacuum significantly extended the lifespan of the lightbulb, making it practical for everyday use. |
In September 1878, Thomas A. Edison began experimenting to develop an electric incandescent lamp with a lifespan suitable for commercial use. By 1879, he had completed his first lamp, which used a platinum filament. Although it generated significant interest, it was soon discovered that the lamp required perfectly consistent pressure and did not meet Edison's expectations. Undeterred, Edison continued his work and, on October 21, 1879, discovered that a high-resistance carbon filament in a vacuum was the key to creating a commercially viable incandescent lamp.

| First day issue of the Electric Light's Golden Jubilee stamp on covers, postmarked at Menlo Park, NJ, on June 5, 1929, signed by Thomas Edison. This special Edison commemorative postage stamp was issued in 1929 to commemorate the 50th anniversary of the invention of the first practical incandescent lamp by Thomas Edison on October 21, 1879. On May 7, 1929, the philatelic world was informed by a telegram from Congressman Ackerman of New Jersey that the department planned to issue this stamp the following month. |
The incandescent lamp was patented on January 27, 1880, following an application submitted on November 4, 1879. A patent for the multiple-arc system was filed on February 6, 1880. This patent encompassed a comprehensive system for generating and distributing electric current for lighting, heating, and power. The "Edison 3-wire" system, invented in 1882, received its patent in March 1883.

On December 31, 1879, Thomas Edison gave a public demonstration of his lights at Menlo Park, New Jersey, where he was living and conducting research. The facility had the capacity for about 500 lights, drawing large crowds of visitors. In January 1881, The Edison Electric Light Company, which had been formed in October 1878 during the Menlo Park experiments, opened an office at 65 Fifth Avenue in New York City. There, an Edison lighting system was showcased for scientists and curious onlookers. The plans for a central station system for New York City were also developed at this location. That same year, Edison Machine Works began manufacturing heavy electrical equipment, and Edison Lamp Company started producing Edison lamps.

A corner card is the printed return address or identifying information typically located in the upper left corner of a postal envelope. It often includes details like the sender's name, business name, logo, and address. Originally used by businesses in the 19th century, corner cards can also serve as a promotional or branding tool for organizations. |
In early 1880, the idea of isolated power plants was explored, leading to the formation of the Edison Company for Isolated Lighting in October 1881 to oversee this area of business. The company sold small generating systems to provide lighting for individual homes, factories, and businesses. On December 31, 1886, it was absorbed by the Edison Electric Light Company, which had financed Edison's electric light experiments in exchange for control of the resulting patents. In 1889, the company merged with several other Edison enterprises to form the Edison General Electric Company.

The Edison Electric Illuminating Company of New York was established on December 17, 1880, to build electric generating stations in New York City. Its first central station, located on Pearl Street in lower Manhattan, began operations on September 4, 1882. This company served as a model for other local illuminating companies that emerged across the United States during the 1880s. In 1901, it merged with the New York Gas & Electric Light, Heat & Power Company to form the New York Edison Company. In 1936, the company was renamed Consolidated Edison Company of New York, Inc.

Edison Lamp Works began producing lamps in the summer of 1880. In early 1881, it became a formal partnership under the name Edison Electric Lamp Company, with partners Thomas Edison, Charles Batchelor, Edward H. Johnson, and Francis R. Upton. The company changed its name to Edison Lamp Company in May 1881, and in 1882, relocated its factory from Menlo Park to East Newark (Harrison), N.J. The partnership was incorporated in 1884. In 1889, it acquired the Sprague Electric Railway and Motor Company, and on April 15, 1892, it merged with the Thomson-Houston Electric Company to form the General Electric Company.

Ernest Robinson Ackerman (17 June 1863 – 18 October 1931) was an American Republican Party politician who represented New Jersey's 5th congressional district in the United States House of Representatives from 1919 to 1931. Ackerman was a famous philatelist, and had created a number of award-winning exhibits of postal stamps and postal history. |
The Edison Manufacturing Company, initially registered as the United Edison Manufacturing Company, was established by Thomas Edison and incorporated in New York City in May 1889. It replaced the Edison United Manufacturing Company, which had been founded in 1886 as a sales agency for the Edison Lamp Company, Edison Machine Works, and Bergmann & Company, manufacturers of electric lighting fixtures, sockets, and other accessories. The Edison United Manufacturing Company was liquidated on October 31, 1889, and succeeded by the Edison Manufacturing Company, which was incorporated in Newark, New Jersey, with its headquarters in West Orange on May 4, 1900.

In 1886, Thomas Edison began constructing a new facility in West Orange, New Jersey. By 1887, his laboratory had relocated from Menlo Park to this larger space in West Orange. The Edison laboratories operated for over 40 years, during which Edison refined his earlier inventions and developed new ones. Notable innovations that emerged from the West Orange laboratories included the motion picture camera, enhanced phonographs, sound recordings, silent and sound films, and the nickel-iron alkaline electric storage battery.

As a U.S. Congressman in 1929, Harold G. Hoffman protested the closure of the Menlo Park post office, which held significant historical value due to its proximity to Thomas Edison’s laboratory, where many of his major inventions, including the incandescent light bulb, were created. Hoffman argued that closing the post office would diminish the historical importance of the area, particularly given its connection to Edison’s work. |

The tablet was the gift to the State of New Jersey of the Edison Pioneers, men who worked side by side with the inventor in the old days, and it was unveiled by Mrs. Edison, the inventor's wife. The tablet was set in a huge granite boulder with a base of concrete containing bricks from the foundation of the first Edison home in Menlo Park. |

| A first day cover featuring an Electric Light Golden Jubilee stamp with imperforations on the top and right edges, along with both horizontal and vertical guide lines. These flat plate stamps were printed in sheets of 400, which were divided into panes of 100 by horizontal and vertical guide lines. The post office prepared the sheets by cutting along these guide lines to create panes of 100 stamps. Each full sheet contained eight plate numbers, with two located on each pane, positioned beside the fifth stamp from the outer corner. |
This Edison commemorative stamp was placed on sale on June 5, 1929, at the post office at Menlo Park, NJ. The stamps were available at other post offices and at the Philatelic Agency, Post Office Department, Washington, DC, as soon after that date. This stamp also issued in coils of 500, sidewise perforated, but not available on the first day of sale.

Due to high demand for the stamp, it was decided to print additional quantities using rapid rotary presses. These were first made available for sale at the Philatelic Agency on June 11, 1929, alongside the coils. The primary demand came from large manufacturers of electrical supplies, who planned to use these stamps for advertising on their mail for several years. This anticipated demand significantly influenced the decision to issue coil stamps in rolls. Since most of the stamps issued in rolls were utilized by companies in the electrical industry, only a limited number reached collectors, making used copies of this stamp rarer than the mint versions from the flat plate or rotary press issues.
