Shiva Ayyadurai

VA Shiva Ayyadurai (Tamilan:சிவா அய்யாதுரை) (born 2 December 1963 in Bombay, India) is an Indian American scientist, inventor and entrepreneur.
As a high school student in 1978, he developed a full-scale emulation of the interoffice mail system, which he called "EMAIL" and copyrighted in 1982. That name's resemblance to the generic term "email" and the claims he later made for the program have led to controversy over Ayyadurai's place in the history of computer technology.
Ayyadurai teaches Systems Visualization at MIT. In 2012, he launched Systems Healthguru and perhaps the most famous of America's alternative medicine practitioners.

an educational program for medical doctors which integrates concepts from systems of holistic medicine such as Siddha, Ayurveda, and Traditional Chinese medicine with systems science and systems biology. Systems Health™ is offered through the Chopra Center with Deepak Chopra, a holistic health/New Age.

VA Shiva Ayyadurai is the founder of the email service company EchoMail, Inc. EchoMail's core technology originated from VA Shiva Ayyadurai's invention for classifying inbound email for the U.S. White House, which was seeking a reliable encryption and classification system for President Clinton's email.

Alexander Graham Bell 's invention of the telephone

Alexander Graham Bell (March 3, 1847 – August 2, 1922) was an eminent scientist, inventor, engineer and innovator who is credited with inventing the first practical telephone.
Bell's father, grandfather, and brother had all been associated with work on elocution and speech, and both his mother and wife were deaf, profoundly influencing Bell's life's work. His research on hearing and speech further led him to experiment with hearing devices which eventually culminated in Bell being awarded the first US patent for the telephone in 1876. In retrospect, Bell considered his most famous invention an intrusion on his real work as a scientist and refused to have a telephone in his study.
Many other inventions marked Bell's later life, including groundbreaking work in optical telecommunications, hydrofoils and aeronautics. In 1888, Bell became one of the founding members of the National Geographic Society. He has been described as one of the most influential figures in human history.

The invention of the telephone is the culmination of work done by many individuals, the history of which involves a collection of claims and counterclaims. The development of the modern electrical telephone involved an array of lawsuits founded upon the patent claims of several individuals and numerous companies.
This article covers the early years from 1844 to 1898, from conception of the idea of an electric voice-transmission device, to failed attempts to use "make-and-break" current, to successful experiments with electromagnetic telephones by Alexander Graham Bell and Thomas Watson, and finally to commercially successful telephones in the late 19th century

Thomas Alva Edison's electric bulb invention

Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman. He 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", he was one of the first inventors to apply the principles of mass production and large-scale teamwork to the process of invention, and because of that, he is often credited with the creation of the first industrial research laboratory.
Edison is the fourth most prolific inventor in history, holding 1,093 US patents in his name, as well as many patents in the United Kingdom, France, and Germany. More significant than the number of Edison's patents, are the impacts of his inventions, because Edison not only invented things, his inventions established major new industries world-wide, notably, electric light and power utilities, sound recording and motion pictures. Edison's inventions contributed to mass communication and, in particular, telecommunications. These included a stock ticker, a mechanical vote recorder, a battery for an electric car, electrical power, recorded music and motion pictures.

His advanced work in these fields was an outgrowth of his early career as a telegraph operator. Edison developed a system 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 Pearl Street in Manhattan, New York.

Edison did not invent the first electric light bulb, but instead invented the first commercially practical incandescent light
