Edward Gokel was 10 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.
Edward Gokel was 13 years old when U.S. President Abraham Lincoln issued the Emancipation Proclamation, declaring the freedom of all slaves in Confederate territory by January 1, 1863. 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.
Edward Gokel was 30 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.
Edward Gokel was 39 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.
Edward Gokel was 49 years old when Spanish–American War: The Treaty of Paris is signed, officially ending the conflict. The Spanish–American War was fought between the United States and Spain in 1898. Hostilities began in the aftermath of the internal explosion of the USS Maine in Havana Harbor in Cuba, leading to US intervention in the Cuban War of Independence. American acquisition of Spain's Pacific possessions led to its involvement in the Philippine Revolution and ultimately in the Philippine–American War.
Edward Gokel was 56 years old when Albert Einstein publishes his first paper on the special theory of relativity. Albert Einstein was a German-born theoretical physicist who developed the theory of relativity, one of the two pillars of modern physics. His work is also known for its influence on the philosophy of science. He is best known to the general public for his mass–energy equivalence formula E = mc2, which has been dubbed "the world's most famous equation". He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory.
