Joseph Niepce developed the world's first photographic image in 1827. Thomas Edison and W K L Dickson introduced the film camera in 1894. But the first projection of an image on a screen was made by a German priest. In 1646, Athanasius Kircher used a candle or oil lamp to project hand-painted images onto a white screen.


Interesting Facts is that The Sumerians invented writing.

The Sumerians, who lived in the Middle East, invented the wheel in about 3450 BC.

Karl Benz invented the first gas powered car. The car had only three wheels. The first car with four wheels was made in France in 1901 by Panhard et LeVassor.

Interesting Facts is that India invented the Number System. Zero was invented by Aryabhatta.

Bulletproof vests, fire escapes, windshield wipers, and laserbprinters,all were invented by women.

In Scotland, a new game was invented. It was entitled Gentlemen Only Ladies Forbidden.... and thus the word GOLF entered into the English language.

The first rocket was invented by the Chinese in the 13th century.

False eyelashes were invented by the American film director D.W. Griffith while he was making his 1916 epic, "Intolerance". Griffith wanted actress Seena Owen to have lashes that brushed her cheeks, to make her eyes shine larger than life. A wigmaker wove human hair through fine gauze, which was then gummed to Owen's eyelids. "Intolerance" was critically acclaimed but flopped financially, leaving Griffith with huge debts that he might have been able to settle easily - had he only thought to patent the eyelashes.

Shakespeare invented the word "assassination" and "bump."

The fortune cookie was invented in 1916 by George Jung, a Los Angeles noodlemaker.

Mr. Peanut was invented in 1916 by a Suffolk, Virginia schoolchild who won $5 in a design contest sponsored by Planters Peanuts.

Everyone thinks it was Whitcomb Judson who invented the zipper but it was really Elias Howe. Elias was so busy inventing the sewing machine that he didn't get around to selling his zipper invention which he called a "clothing closure".


Interesting Facts is that The oiuja board was invented by Isaac and William Fuld, and was patented July 1, 1892.

The hamburger was invented in 1900 by Louis Lassen. He ground beef, broiled it, and served it between two pieces of toast.

In 2003, scientists managed to create a material dense enough to stop light mid-way through it, allowing them to observe static light.

The Can opener wasn't invented until 48 years after the can.

Nobel Prize resulted from a late change in the will of Alfred Nobel, who did not want to be remembered as a propagator of violence-he invented dynamite.

Diet Coke was only invented in 1982.

Dry cereal for breakfast was invented by John Henry Kellogg at the turn of the century Inventor Samuel Colt patented his revolver in 1836.

The bagpipe was originally made from the whole skin of a dead sheep.

TRANSISTOR...Invention

Fascinating facts about the invention of Transistors by John Bardeen, Walter Brattain, and William Shockley in 1947. TRANSISTOR
Almost every piece of equipment that stores, transmits, displays, or manipulates information has at its core silicon chips filled with electronic circuitry. These chips each house many thousands or even millions of transistors. The history of the transistor begins with the dramatic scientific discoveries of the 1800's scientists like Maxwell, Hertz, Faraday, and Edison made it possible to harness electricity for human uses. Inventors like Braun, Marconi, Fleming, and DeForest applied this knowledge in the development of useful electrical devices like radio.
Their work set the stage for the Bell Labs scientists whose challenge was to use this knowledge to make practical and useful electronic devices for communications. Teams of Bell Labs scientists, such as Shockley, Brattain, Bardeen, and many others met the challenge.--and invented the information age. They stood on the shoulders of the great inventors of the 19th century to produce the greatest invention of the our time: the transistor. The transistor was invented in 1947 at Bell Telephone Laboratories by a team led by physicists John Bardeen, Walter Brattain, and William Shockley. At first, the computer was not high on the list of potential applications for this tiny device. This is not surprising—when the first computers were built in the 1940s and 1950s, few scientists saw in them the seeds of a technology that would in a few decades come to permeate almost every sphere of human life. Before the digital explosion, transistors were a vital part of improvements in existing analog systems, such as radios and stereos. When it was placed in computers, however, the transistor became an integral part of the technology boom. They are also capable of being mass-produced by the millions on a sliver of silicon—the semiconductor chip. It is this almost boundless ability to integrate transistors onto chips that has fueled the information age. Today these chips are not just a part of computers. They are also important in devices as diverse as video cameras, cellular phones, copy machines, jumbo jets, modern automobiles, manufacturing equipment, electronic scoreboards, and video games. Without the transistor there would be no Internet and no space travel. In the years following its creation, the transistor gradually replaced the bulky, fragile vacuum tubes that had been used to amplify and switch signals. The transistor became the building block for all modern electronics and the foundation for microchip and computer technology.

Fascinating facts about Ernst Alexanderson inventor of the Alexanderson alternator in 1909.

Fascinating facts about Ernst Alexanderson inventor of the Alexanderson alternator in 1909.	Ernst Alexanderson
AT A GLANCE: Electrical engineer and inventor Ernst Fredrick Werner Alexanderson developed pioneering technological concepts during the early 20th century that contributed to the birth of the broadcasting industry. Alexanderson's numerous discoveries formed the basis for the technology that would make the transmission of voice, music, and pictures possible; his more than 340 patents and affiliations with some of the world's foremost scientists and business executives made him a central figure in the early years of broadcasting and earned him a place on the list of the most prolific U.S.-based inventors of all time. He designed the Alexanderson alternator, a high-frequency generator for longwave transmission, which made modulated (voice) radio broadcasts practical. Source: Inventor of the Week Inventor: Ernst Fredrick Werner Alexanderson Criteria: First to invent. First to patent. First practical. Birth: January 25, 1878 in Uppsala, Sweden Death: May 14, 1975 in Schenectady, New York Nationality: Swedish Invention: Alexanderson alternator Function: noun / alternator named after its inventor Definition: A rotating machine for the generation of high frequency alternating current up to 100 kHz, for the purpose of radio communication. Patent: 1,008,577 (US)  issued, November 14, 1911
