Inventions around the World
Telephone:
While Italian innovator Antonio Meucci is credited with inventing the first basic phone in 1849, and Frenchman Charles Bourseul devised a phone in 1854, Alexander Graham Bell won the first U.S. patent for the device in 1876.
1911 - American Telephone and Telegraph (AT & T) acquire the Western Union Telegraph Company in a hostile takeover. They purchased stocks in the company covertly and the two eventually merged.
Within 20 years of the 1876 Bell patent, the telephone instrument, as modified by Thomas Watson, Emil Berliner, Thomas Edison, and others, acquired a functional design that has not changed fundamentally in more than a century.
Car:
Leonardo da Vinci considered the idea of a self-propelled vehicle in the 15th century.
Nicolas-Joseph Cugnot of France was the constructor of the first true automobile. Cugnot’s vehicle was a huge, heavy, steam-powered tricycle

Microwave:
Percy Spencer developed and patented the first microwave oven after noticing that a magnetron was emitting heat-generating microwaves during an experiment with radar in 1945.
This 1976 model was manufactured in Japan by Matsushita Electric Industrial Co. for J.C. Penney and was sold to Jeff and Jan Thompson for $261.35, including tax and an Assurance Performance Plan.
In the 1970s, food companies expanded their offerings of frozen, microwavable dinners and snacks to meet the demands of busy families and individuals with complex schedules or no inclination to cook.
Internet:
Berners-Lee certainly invented the web browser and created the world’s first website – info.cern.ch –on 20 December 1990, which was viewable at CERN.
The World Wide Web opened for public use in 1991, entering into general widespread use following 30 April 1993, when Berners-Lee’s invention entered the public domain and after his writing of the first version of HTML.
British computer scientist Tim Berners-Lee invented the World Wide Web, a key part of the Internet used today. He proposed the idea in March 1989, while working for CERN.
Steam engine
In 1698 Thomas Savery patented a pump with hand-operated valves to raise water from mines by suction produced by condensing steam.
In about 1712 another Englishman, Thomas Newcomen, developed a more efficient steam engine with a piston separating the condensing steam from the water.
In 1765 James Watt greatly improved the Newcomen engine by adding a separate condenser to avoid heating and cooling the cylinder with each stroke.
