On January 27, 1880, Edison received the patent for his electric light.

The invention of the light bulb and how it changed the world He developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and a long-lasting, practical electric light bulb.

Thomas Edison. Edison realized that the problem with Swan’s design was the filament. A thin filament with high electrical resistance would make a lamp practical because it would require only a little current to make it glow. He demonstrated his light bulb in December 1879.

people innovated light bulbs called (LED), also they have a larger wattage capacity, smaller light bulbs, they also have light bulbs of different colors and different shapes.

Like all great inventions, the light bulb can’t be credited to one inventor. It was a series of small improvements on the ideas of previous inventors that have led to the light bulbs we use in our homes today. Learn more about the history of the incandescent light bulb.

The electric light bulb has been called the most important invention since man-made fire. The light bulb helped to establish social order after sundown, extended the workday well into the night, and allowed us to navigate and travel safely in the dark. Without the light bulb, there would be no nightlife.

Read a biography of Benjamin Banneker, the famous African-American inventor who developed America’s first fully functioning clock.

1752

1709

His early accomplishments included constructing an irrigation system for the family farm and a wooden clock that was reputed to keep accurate time and ran for more than 50 years until his death. In addition, Banneker taught himself astronomy and accurately forecasted lunar and solar eclipses.

Banneker’s interest in astronomy allowed him to accurately predict eclipses. This lead to his most noteworthy contribution–Banneker Almanacs. From 1792 – 1797, Banneker wrote and published an almanac each year. These almanacs were used by farmers and fishermen to predict tides, eclipses and astrological phenomena.

His significant accomplishments include the successful prediction of a solar eclipse, publishing his own almanac, and the surveying of Washington, D.C. Banneker spent most of his life on his family’s 100-acre farm outside Baltimore.

Benjamin Banneker, (born November 9, 1731, Banneky farm [now in Oella], Maryland [U.S.]—died October 19? [see Researcher’s Note], 1806, Baltimore, Maryland, U.S.), mathematician, astronomer, compiler of almanacs, inventor, and writer, one of the first important African American intellectuals.

Benjamin Banneker died on Sunday, October 9, 1806 at the age of 74. Banneker’s clock, most of his personal belongings and nearly all his writings, research, and books were thought to be destroyed in a mysterious house fire started by arsonists while his funeral was going on a few hundred yards away.

Banneker lived in a small cabin on his farm in Maryland. He died in 1806, and while his funeral was in progress, his house caught fire. It burned all Banneker’s modest possessions, including a wooden clock he had constructed himself.

Banneker built a “work cabin” with a skylight to study the stars and make calculations. Working largely alone, with few visitors, he compiled results which he published in his Almanac.

Answer and Explanation: It appears the clock is not named after Banneker. Many believe that Big Ben takes its name from Benjamin Hall, one of the British officials who oversaw the construction of the clock tower, but it appears Banneker was not the inspiration for this name.

The name of Benjamin Banneker, the Afro-American self-taught mathematician and almanac-maker, occurs again and again in the several published accounts of the survey of Washington City [D.C.] begun in 1791, but with conflicting reports of the role which he played.
