Without mobile and computer, today’s world cannot be imagined. These two inventions have changed the world of telecommunication and information technology (IT). Both of these great inventions were associated with Today, April 3. In the year 1973, Martin Cooper made the first call to Bell Labs’s Joel S. Engel from a hand-held mobile phone. Cooper is called the father of today’s mobile phone. At that time Cooper used to work for the Motorola company. In the US, the use of base phones was being used since 1930, but the use of the handheld phone was done by Cooper for the first time on April 3.
It is also a coincidence that on the same day in 1981, the first portable computer sample was presented by Adam Osborne of Osborne Computer Corporation in Brooks Hall, San Francisco. Its weight was approximately 24 pounds.
April 3rd also holds special significance for India too. Sam Manekshaw, who was one of the most famous and greatest military officers of the Indian Army, was born in 1914. He was the first officer in the Indian Army, who was given the rank of Field Marshal. In his four-decade military career, he fought 5 battles. Manekshaw, who served in the British Indian Army in World War II, was a special part of India’s victory in 1971 in a war against Pakistan.
