Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor, scientist and businessman who developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and a long-lasting, practical electric light bulb. Dubbed "The Wizard of Menlo Park" (now Edison, New Jersey) by a newspaper reporter, he was one of the first inventors to apply the principles of mass production and large teamwork to the process of invention, and therefore is often credited with the creation of the first industrial research laboratory. Edison is considered one of the most prolific inventors in history, holding 1,093 U.S. patents in his name, as well as many patents in the United Kingdom, France, and Germany. He is credited with numerous inventions that contributed to mass communication and, in particular, telecommunications. His advanced work in these fields was an outgrowth of his early career as a telegraph operator. Edison originated the concept and implementation of electric-power generation and distribution to homes, businesses, and factories – a crucial development in the modern industrialized world. His first power station was on Manhattan Island, New York.
Thomas Edison founded the Edison Portland Cement Company in 1899 in New Village, New Jersey, after a failed iron ore mining venture. Recognizing the potential of sand waste from his ore-crushing operations as a concrete ingredient, Edison retrofitted his machinery and rock-crushing technology to manufacture cement. He introduced several groundbreaking innovations, notably the installation of long, rotating kilns that were 150 feet in length—nearly double the industry standard of 60 to 80 feet—which significantly boosted production efficiency. However, the company faced financial instability in its early years due to Edison’s decision to license his kilns to competitors, which saturated the market and led to price reductions.
The company gained significant recognition for Edison’s ambitious yet largely unsuccessful attempt to mass-produce “single-pour” concrete houses. He designed intricate cast-iron molds capable of forming an entire two-story home, including the roof, walls, and even bathtubs, in a single continuous pour. However, the immense cost and weight of these molds deterred builders. Despite only a few of these homes being constructed, the company secured a major contract in 1922 to supply approximately 45,000 barrels of cement for the construction of the original Yankee Stadium. Remarkably, the resulting concrete proved so durable that it remained largely untouched during the stadium’s 1970s renovations. Amidst the hardships of the Great Depression, the Edison Portland Cement Company was dissolved in December 1931 and succeeded by the Edison Cement Corporation, which continued operations until June 1942.
A stock certificate is issued by businesses, usually companies. A stock is part of the permanent finance of a business. Normally, they are never repaid, and the investor can recover his/her money only by selling to another investor. Most stocks, or also called shares, earn dividends, at the business's discretion, depending on how well it has traded. A stockholder or shareholder is a part-owner of the business that issued the stock certificates.
