Handy What was Menlo Park? This was the first business or institution with the sole purpose of inventing.

They would do research and science and then apply it to practical applications that could be manufactured and built on a large scale. There were a lot of employees working for Edison at Menlo park. These workers were inventors, too, and did a lot of work on Edison's ideas to help turn them into inventions.

Thomas Edison has the patents and credits for many inventions. Three of his most famous include: The Phonograph - This was the first major invention by Edison and made him famous.

It was the first machine that was able to record and playback sound. Light Bulb - Although he did not invent the first electric light, Edison made the first practical electric light bulb that could be manufactured and used in the home. The Motion Picture - Edison did a lot of work in creating the motion picture camera and helping move forward the progress of practical movies. During this time he made and patented many improvements to telegraphs and even created an electric pen in The electric pen had declining success until when others produced electric pens that did not require a battery as Edison's invention did.

In , as the result of experimentation with the telephone and telegraph, Thomas Edison invented the phonograph. This led to the establishment of the Edison Speaking Phonograph Company in His interest in the device returned in after others made improvements to the machine.

This led Edison to make his own improvements to the device. Thomas Edison's most famous inventions revolved around electricity.

Thomas Edison

He is known as the creator of the incandescent light bulb and bringing electric light to the streets and homes. In , after experimenting with numerous types of lighting elements called filaments at his Menlo Park lab, he developed a lamp that used a carbon conducting element which received an electric current to produce light inside of a globe-shaped glass container. The resulting light bulb proved to be stable, lasting over 13 hours.

A few months after he received a patent for this invention, he found other materials that would allow a bulb to last for hundreds of hours. While he did not invent the world's first light bulb, he did invent the incandescent type; this technology was the first to make incandescent light bulbs useful in homes.

Eventually, it also led to his invention of the electric chandelier. He also invented a new type of generator which, while later proven to be inefficient, was shown at the Paris Electrical Exposition of and hailed at the time as a technological wonder. Edison then created the world's first electric power station for public use in London, England in In the same year, he established a power station on Manhattan's Pearl Street to generate electricity for New York street lights and homes.

Only five years later there were more than a hundred stations in America alone, which Edison owned and operated. The kinetograph was the first motion picture camera and the kinetoscope was a small box like device that allowed a single person to view movies when looking through it. The kinetoscope eventually evolved into the kinetoscope projector, which allowed many people to view movies at one time.

Later, he developed a kinetophone to synchronize sound with film, but had little success. By , the growing film industry no longer held interest for Edison and he removed himself from the motion picture industry.

Who Was Thomas Alva Edison?

Later Years Edison significantly slowed his creation of inventions and in , he reorganized his many company's under a single organization called Thomas A. His work included stock tickers, fire alarms, methods of sending simultaneous messages on one wire, and an electrochemical telegraph to send messages by automatic machinery. The crowning achievement of this period was the quadruplex telegraph, which sent two messages simultaneously in each direction on one wire.

The problems of interfering signals in multiple telegraphy and high speed in automatic transmission forced Edison to extend his study of electromagnetism and chemistry. As a result, he introduced electrical and chemical laboratories into his experimental machine shops.

Near the end of , observations of strange sparks in telegraph instruments led Edison into a public scientific controversy over what he called "etheric force," which only later was understood to be radio waves. Menlo Park In , Edison created a freestanding industrial research facility incorporating both a machine shop and laboratories.

Here in Menlo Park, on the rail line between New York City and Philadelphia, he developed three of his greatest inventions. Urged by Western Union to develop a telephone that could compete with Alexander Graham Bell's, Edison invented a transmitter in which a button of compressed carbon changed its resistance as it was vibrated by the sound of the user's voice, a new principle that was used in telephones for the next century.

Business Leaders: Thomas Edison

While working on the telephone in the summer of , Edison discovered a method of recording sound, and in the late fall he unveiled the phonograph. This astounding instrument brought him world fame as the "Wizard of Menlo Park" and the "inventor of the age. During his lamp experiments, he noticed an electrical phenomenon that became known as the "Edison effect," the basis for vacuum-tube electronics.

He left Menlo Park in to establish factories and offices in New York and elsewhere.

Over the next five years he manufactured, improved, and installed his electrical system around the world. West Orange Laboratory In , Edison built an industrial research laboratory in West Orange, New Jersey, that remained unsurpassed until the twentieth century. For four years it was the primary research facility for the Edison lighting companies, and Edison spent most of his time on that work.His work included stock tickers, fire alarms, methods of sending simultaneous messages on one wire, and an electrochemical telegraph to send messages by automatic machinery.

Edison hired "muckers" to help him out.

One of the accidental discoveries made in the Menlo Park laboratory during the development of the incandescent light anticipated the British physicist J. Others who developed early and commercially impractical incandescent electric lamps included Humphry Davy , James Bowman Lindsay , Moses G.

In just over a decade, Edison's Menlo Park laboratory had expanded to occupy two city blocks. In , Edison was honored with a Technical Grammy Award. Colin Mason.
