Who invented the light bulb

Who invented the light bulb

Who invented the light bulb? No, it wasn't Thomas Edison. Light bulbs - in particular Starr's electric lamp - were in use 50 years before Edison applied for the patent in 1879. In addition, British inventor Joseph Swan was awarded a light bulb patent the previous year. Edison went on to make big buck from the light bulb but Swan sued Edison for infringement and won. As part of the settlement, Edison was forced to take Swan in as a partner but later bought him out in the company that was to become General Electric.

In 1883, the US Patent Office ruled that Edison's patent on the light bulb might have been based on that of William Sawyer and were invalid. It is not that Edison stole the idea: there are many examples of different people thinking up the same concept at more-or-less the same time.

Thomas Alva Edison (1847 - 1931) certainly was not a lazy guy. He filed 1,093 patents, including those for electric railways and the movie camera. When he died in 1931, he held 34 patents for the telephone, 141 for batteries, 150 for the telegraph and 389 patents for electric light and power. Unlike Leonardo da Vinci who never built the inventions he designed, Edison was not just a great theorist. He coined the phrase: "Genius is 1% inspiration and 99% perspiration." He also said: "There are no rules here. We're trying to get work done."

Soft Drink Inventions

The term "soda water" was coined in 1798. The soda fountain was patented by Samuel Fahnestock in 1819, with the first bottled soda water available in 1835. The first ice-cream soda was sold in 1874 in the US. The first cola-flavored beverage was introduced in 1881. Coca-Cola was invented in 1886 in Atlanta, Georgia by Dr. John S. Pemberton. Pepsi-Cola was invented by Caleb Bradham 12 years later. In 1929, the Howdy Company introduced its "Bib-Label Lithiated Lemon-Lime Sodas," which became 7 Up, which was invented by Charles Leiper Grigg.

Red Bull was introduced by Austrian Dietrich Mateschitz and Chaleo Yoovidhya, from Thailand, in 1987. It is based on the Thai drink called Krating Daeng which means red bull.

The first diet soft drink, called the "No-Cal Beverage" is launched in 1952. Aluminum cans were introduced in 1957 and two years later the first diet cola went on sale.

The most popular beverage in the world is tea.

Invention of Velcro

After a walk in the Swiss woods with his dog one day in 1941, Georges de Mestral was astounded by the ability of burrs to stick to his dog's coat and his own clothes. When he got home, he shoved burrs under a microscope and saw that its barbed seed pods hooked easily with the looped fibers of his coat. He realized that he could produce a new type of fastening product.

It was not an easy task, though, eventually taking him 10 years to perfect the product, using cotton but settling on nylon. At first people laughed at the idea but by the time Georges de Mestral (1907 - 1990) received a patent for the product in 1955 the idea for the "zipperless zipper" was well received. He named the product Velcro, from the French words velours (velvet) and crochet (hook).

Today, Velcro is used almost everywhere: apparel, shoes, leashes, nuclear power plants, battle tanks, in the space shuttle and many more. All thanks to the burr plant.

Graham Bell Dislike Phone

Alexander Graham Bell, who was awarded the patent for the invention of the telephone, disliked telephones so much that he refused to have one in his office. When Bell passed away in 1922, every telephone served by the Bell system in the USA and Canada was silent for one minute.
