The early invention is critical in its own manner and has been the best in what it is. Without these inventions, one could not lead a comfortable and easy life as we see today. We should thank all the geniuses for the great findings they have contributed to mankind by sacrificing their lives for our betterment.
Telephone:Alexander Graham Bell, one of Bell's assistants, was trying to reactivate a telegraph transmitter. Having the sound, Bell believed that he could solve the problem of sending a human voice over a wire. He first figured out how to transmit a simple current and received a patent for that invention on March 7, 1876.
Bulb:
By January 1879, Thomas Edison had built his first high-resistance, incandescent electric light high-resistance in Menlo Park, New Jersey. It worked by passing electricity through a thin platinum filament in the glass vacuum bulb, which delayed the filament from melting.
Mobile Phone:
Martin Cooper wanted people to have the freedom to talk on the phone away from their cars. So in reaction, he and Motorola embarked on a project to create more portable devices. Motorola spent three months building a prototype for a portable, mobile handset that Cooper publicly demonstrated in April of 1973.Television:
John Logie Baird's invention, the pictorial-transmission machine called a televisor, "used mechanical rotating disks to scan moving images into electronic impulses. This information was then transmitted by cable to a screen where it showed up as a low-resolution pattern of light and dark. His first television was invented in 1923.
Car:
Karl Benz was inspired by Nikolaus Otto's engine innovations, Benz developed a commercially successful 2-stroke engine. He then designed a three-wheeled vehicle and a 4-stroke engine to power it. Benz patented his car in 1886 but was determined to perfect its design before beginning production. On January 29,1886, Karl Benz applied for a patent for his "vehicle powered by a gas engine". The patent number 37435 may be regarded as the birth certificate of the automobile. In July 1886, the newspapers reported on the first public outing of the three-wheeled Benz patent motor car.
