About Thomas Alva Edison

Thomas Alva Edison was the phenomenal American inventor who holds the world-record of 1093 patents. Also, he created the world’s first industrial research laboratory. Edison was born on 11th February 1847, in Milan, Ohio – U.S.

Edison’s patents and numerous inventions contributed significantly to mass communications and telecommunications. Stock ticker, phonograph, the practical electric light bulb, motion picture camera, mechanical vote recorder and a battery for the electric car were some of his notable inventions.

He sold newspapers to passengers traveling along the Grand Trunk Railroad line during his early years. This led him to start his own newspaper named as the ‘Grand Trunk Herald’. The access to up-to-date information in this newspaper became quite a hit between the masses. Also, it was the first of the many more to come business ventures by Edison.

Education, Career and Achievements

• Education:
• Thomas Alva Edison always had a thrust of knowledge within him, and due to that, at an early age, he started reading a wide range of books and different subjects. 
• Edison’s higher education did not include any university or attending college; instead, he was primarily self-taught. 
• The absence of a well-defined curriculum led him to develop the skill of self-education and independent learning, which remained with him all his life.
• Career:
• He began his career as an inventor when he moved to New York. 
• He devoted the decade of the 1870s to conducting experiments on the telephone, phonograph, electric railway, electric lighting, and other developing inventions. 
• His first round of fame was brought by the design of the phonograph in 1877, which took his status to greater heights. 
• He formed Edison Electric Light Company in 1878 in New York City.
• Achievement:
• He was felicitated with several awards and medals for his generous contribution to humankind. 
• Some of them include the Distinguished Service Medal by the U.S. Navy and Congressional Gold Medal by the U.S. Also, he was decorated with the “Officer of the Legion of Honour” by France. 
• He was welcomed into the New Jersey Hall of Fame and Entrepreneur Walk of Fame.

The invention of the Light Bulb

The greatest challenge faced by Thomas Alva Edison was to develop a practical luminous, electric light. He accomplished this using lower current electricity, an improved vacuum inside the globe and a small carbonized filament which is a stitched thread that burned for thirteen and a half hours. He was successful in producing a reliable, long-lasting source of light.

Did Edison really invent the light bulb?

The Phonograph

The tinfoil Phonograph was Thomas Edison’s first greatest invention in 1877. It was the first machine to record and play a person’s voice. Edison recited the rhyme “Mary Had a Little Lamb” on a tin cylinder that captured the recording.

He also recommended other uses for the phonograph, such as letter writing and dictation, record music boxes, etc. Edison’s device phonograph played using cylinders rather than discs. It consisted of two needles, one for recording and one for playback.

Edison’s contribution in the field of electricity

A system of conductors, meters, current switches, etc. was designed by Edison as he knew that his light bulb invention would be ineffective without a proper method to deliver electricity. Edison improved the designs of generators, which led him to invent more efficient power output generators than the existing ones at that time. Hence, this was marked as the beginning of the electric age.
