Few Fascinating inventions

Air conditioning

Have you ever wondered who invented the air conditioner that keeps us cool in the hot, humid summers? It was Willis Carrier who invented world's first air conditioning system way back in 1902. The machine that he built could control temperature, humidity, and air circulation besides cleansing the air. Carrier refined his invention over the years. During the World War 1, the Buffalo Forge Company of which Carrier was an employee, decided to focus exclusively to manufacturing and not spare time and money for the model that Carrier was developing. Determined that his hard work meets its worth, Carrier along with six other engineers, founded the Carrier Engineering Corporation in 1915. The company catered to the cooling needs of the buildings.

Carrier is included in the list of US's National Inventors Hall of Fame.

Camera

Before digital cameras had made their foray, the cameras that used roll films were used by everybody to click pictures. George Eastman was the person behind the invention of the rolled film and the first camera that used such films, under the brand name of Kodak. The roll films also propelled the making of the first motion picture. George Eastman not only helped us to click still pictures but was instrumental in the birth of the massive motion picture industry as well. Eastman was not only a great inventor but a generous donor too who donated large sums of money to various organizations during his lifetime.

Safety pin

Walter Hunt was one of the most creative inventors of all times. He invented a huge assortment of items like safety pin, lockstitch sewing machine, flax spinner, knife sharpener, hard coal-burning stove, streetcar bell, artificial stone, street sweeping machinery and the ice plough. He was born in New York in 1796. He invented the safety pin when he had to repay a debt that he had taken from one of his friend. He molded a brass wire and fitted it with clasp to make the safety pin. He then sold the patent to W. R. Grace and Company who in turn made millions from his invention in the subsequent years.

Telephone

Which is the device that helps people stay connected at all times? Telephone, of course. Alexander Graham Bell invented the first telephone in 1876. Bell's parents were deaf and so he worked extensively on the hearing devices. Apart from telephones, he also did commendable job on the field of telecommunication and aeronautics. He was also one of the founder members of the National Geographic Society. He made the first long distance telephone call in 1876 when he called from Cambridge, Thomas A Watson in Boston.

Zipper

The zipper was invented in 1917 and was called the "continuous clothing closure" then. Gideon Sundback invented it and it was used for in tobacco bags and boots. It took few years before it was used in garments. B.F. Goodrich Company gave the name zipper to the product. The company initially targeted the zipper for kids as it helped them to do up their clothing without adult supervision.

Play-Doh

All of us love playing with the "Play-doh" - the dough that helps kids carve out various figurines. But, have you spared a thought about who invented the dough and how? The "Play-doh" was invented in 1956 and that too accidentally! Noah and Joseph McVicker originally developed the product as wallpaper cleaner. Joseph's sister was a teacher, who took the dough to her class to ask kids make figures out of it. Thus, world discovered the Play-doh. The product was initially available only in off white color; the colored versions of the dough were made available from the following year.

Lead Pencils

The lead pencils actually do not contain any lead. They were invented in 1564 with the discovery of a humongous graphite mine in Cumbria, England. At the time of discovery, the discovered element was called black lead, as it resembled the ore, lead. Graphite was cut into rods and inserted into the wooden cases to make pencils.

Potato Chips

You all love gorging on crunchy potation chips. But do you know when did the first batch of potato chips made their foray? The credit of inventing the delicious potato chips goes to George Crum in 1853, who was an American chef. The chips were made for a customer who complained that the French fries made by Crum were too thick. He made the next batch thinner but the customer was still not happy. Annoyed, he made the third batch extremely thin and to his surprise, they all were lapped up.

Computers

One invention that has found its applications in every sphere of life and work is computers. The birth and the development of computers is a complex history spanning several centuries.

The word computer was first used in 1613. In 1822, Charles Babbage started his work on the Difference Engine that was capable of computing several numbers at the same time and take out printouts. Because of the dearth of funds, he was never ever able to complete it. In 1837, he began working on the Analytical Engine that came with an Arithmetic Logic Unit, a flow control and an integrated memory. This too met the same fate as the Difference engine.

Konrad Zuse of Germany created the first functional computer in 1938.

The Atanasoff-Berry Computer or ABC as it was better known as, was the first electrical computer created. It had no CPU and used Boolean logic and binary math. IBM 701 was the first mass produced computer by any company. The same company introduced the first Personal Computer in 1981.

Apple Inc made its foray in 1976 when it started selling the computer kit, hand built by Steve Wozniak. Subsequently the company made Apple II and Apple III. It came out with Macintosh in 1984. The machine did not work with any programming language at that time.

The first laptop was created in 1981 by Adam Osborne and was named Osborne I.
