Sitting in his workshop one day,tired and discouraged, he popped a piece of surplus stock into his mouth. In 1870, he opened the world’s first chewing gum factory making Adams New York No. 1. He was born in 1818 and died in 1905
Invention of Zipper by Gideon Sundback, in 1913. The design used today, based on interlocking teeth, was invented by an employee of Whitcomb Judson's, Swedish born scientist Gideon Sundback. After that more improvements patented in 1917 as the "Separable Fastener". Only after Gideon Sundbach, had remodeled Judson's fastener into a more streamlined and reliable form, was the fastener a success.
Yale Lock was invented by Linus Yale Jr. in 1860. He was born in April 4, 1821 and died in Dec 25 1968. Yale's lock used a flat key with serrated edges like the ones we still use today. Yale lock is based on a mechanism first employed by the ancient Egyptians over 4000 years ago.
The first hair dryer was the vacuum cleaner! In early models of hair dryer, the front of a vacuum cleaner sucked air in, the back blew air out, and the hose could be attached to either end.
The first hair dryer was invented in 1920 but the size of the hair dryer was too large and heavy. In 1951 was the first really workable dryer made. The device consisted of a hand-held dryer connected to a pink plastic bonnet fitted over the woman’s head.
The ballpoint was invented in 1935 by Ladislas Bro and his brother Georg. Ladislas Biro was very talented and confident of his abilities, but he had never had a pursuit that kept his interest and earned him a good living. He had studied medicine, art, and hypnotism, and in 1935 he was editing a small newspaper-where he was frustrated by the amount of time he wasted filling fountain pens and cleaning up ink smudges.
Milton Reynolds fifty-four-year-old Chicago salesman became the first American manufacturer to market a ballpoint pen successfully. The first successful ballpoint came on an October morning in 1945. On that first day of sales, Gimbels sold out its entire stock of 10,000 pens-at $12.50 each!
A German Chemist Felix Hoffmann produced a stable form of acetylsalicylic acid, more commonly known as aspirin, in 1897. Basically, he is searching for something which can give relief to his father. He studied French chemist Charles Gergardt's experiments and "rediscovered" acetylsalicylic acid--or aspirin, as we now know it.
George Westinghouse in 1869 was the first person who invented the air brake and revolutionized the railroad industry, making braking a safer venture and thus permitting trains to travel at higher speeds. After that he made many changes to improve the brakes. By 1905, over 2,000,000 freight, passenger, mail, baggage and express cars and 89,000 locomotives were equipped with the Westinghouse Quick-Action Automatic Brake

He represented by a string of 0s and 1s a laser reads the binary patterns etched on a photosensitive platter. Russell isn't able to convince the music industry to adopt his invention, but 20 years later, Time Warner and other CD manufacturers pay a $30 million patent infringement settlement to Russell's former employer, the Optical Recording Co.
