David Barnhart was 17 years old when Petroleum is discovered in Titusville, Pennsylvania leading to the world's first commercially successful oil well. Petroleum is a naturally occurring, yellow-to-black liquid found in geological formations beneath the Earth's surface. It is commonly refined into various types of fuels. Components of petroleum are separated using a technique called fractional distillation, i.e. separation of a liquid mixture into fractions differing in boiling point by means of distillation, typically using a fractionating column.
David Barnhart was 19 years old when Abraham Lincoln is elected as the 16th President of United States. Abraham Lincoln was an American statesman and lawyer who served as the 16th President of the United States from March 1861 until his assassination in April 1865. Lincoln led the United States through the American Civil War—its bloodiest war and perhaps its greatest moral, constitutional, and political crisis. In doing so, he preserved the Union, abolished slavery, strengthened the federal government, and modernized the economy.
David Barnhart was 38 years old when Thomas Edison demonstrates incandescent lighting to the public for the first time, in Menlo Park, New Jersey. Thomas Alva Edison was an American inventor and businessman, who has been described as America's greatest inventor. He developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and the long-lasting, practical electric light bulb. Dubbed "The Wizard of Menlo Park", he was one of the first inventors to apply the principles of mass production and large-scale teamwork to the process of invention, and is often credited with the creation of the first industrial research laboratory.
David Barnhart was 46 years old when The Great Blizzard of 1888 struck the northeastern United States, producing snowdrifts in excess of 50 ft (15 m) and confining some people to their houses for up to a week. The Great Blizzard of 1888 or Great Blizzard of '88 was one of the most severe recorded blizzards in the history of the United States of America. The storm, referred to as the Great White Hurricane, paralyzed the East Coast from the Chesapeake Bay to Maine, as well as the Atlantic provinces of Canada. Snowfalls of 10 to 58 inches fell in parts of New Jersey, New York, Massachusetts, Rhode Island, and Connecticut, and sustained winds of more than 45 miles per hour (72 km/h) produced snowdrifts in excess of 50 feet (15 m). Railroads were shut down, and people were confined to their houses for up to a week. Railway and telegraph lines were disabled, and this provided the impetus to move these pieces of infrastructure underground. Emergency services were also affected.
David Barnhart was 51 years old when Electrical engineer Nikola Tesla gives the first public demonstration of radio in St. Louis, Missouri. Nikola Tesla was a Serbian American inventor, electrical engineer, mechanical engineer, physicist, and futurist who is best known for his contributions to the design of the modern alternating current (AC) electricity supply system.
David Barnhart died on 7 May 1901 at the age of 59
