Answer:
Martin Cooper is the inventor of Mobile Phones.
Explanation:
Martin Cooper, byname Marty Cooper, (born December 26, 1928, Chicago, Illinois, U.S.), the American engineer who led the team that in 1972–73 built the first mobile cell phone and made the first cell phone call. He is widely regarded as the father of the cellular phone.
Cooper graduated from the Illinois Institute of Technology (IIT) in Chicago with a bachelor’s degree in electrical engineering (1950). He joined the U.S. Navy and served during the Korean War. After the war, he joined the Teletype Corporation, and in 1954 he began working at Motorola. He earned a master’s in electrical engineering from IIT (1957). At Motorola, Cooper worked on many projects involving wireless communications, such as the first radio-controlled traffic-light system, which he patented in 1960, and the first handheld police radios, which were introduced in 1967. He later served as a vice president and director of research and development (1978–83) for the company.
Mobile telephones had been introduced by the American Telephone & Telegraph Company (AT&T) in 1946. However, in a given area only 11 or 12 channels were available, so users often had to wait to use the system. Another weakness of the first mobile phones was that a large amount of power needed to run them could be supplied only by car batteries. Thus, there were no truly portable phones but only car phones.
The most famous social media app "Facebook" was founded by Mark Zuckerberg.
Mark Elliot Zuckerberg ( born May 14, 1984) is an American media magnate, internet entrepreneur, and philanthropist. He is known for co-founding Facebook, Inc. and serves as its chairman, chief executive officer, and controlling shareholder. He also is a co-founder of the solar sail spacecraft development project Breakthrough Starshot and serves as one of its board members.
Born in White Plains, New York, Zuckerberg attended Harvard University, where he launched the Facebook social networking service from his dormitory room on February 4, 2004, with college roommates Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes. Originally launched to select college campuses, the site expanded rapidly and eventually beyond colleges, reaching one billion users by 2012. Zuckerberg took the company public in May 2012 with majority shares. In 2007, at age 23, he became the world's youngest self-made billionaire. As of November 2020, Zuckerberg's net worth is $96.7 billion, making him the 4th-richest person in the world.[8] He is the only person under 40-years-old in Forbes' list of the 20 richest people.
Since 2010, Time magazine has named Zuckerberg among the 100 wealthiest and most influential people in the world as a part of its Person of the Year award. In December 2016, Zuckerberg was ranked 10th on Forbes list of The World's Most Powerful People.
