J. Erik Jonsson
John Erik Jonsson (6 September 1901 – 31 August 1995) was a co-founder and early president of Texas Instruments Incorporated. He became Mayor of Dallas, a major advocate of the creation of Dallas/Fort Worth International Airport, and a philanthropist in later years. Biography Early life Erik Jonsson was born on 6 September 1901 in the Brooklyn borough of New York City. His parents, John Peter and Ellen Charlotte (Palmquist) Jonsson, were both born in Sweden and independently migrated to the United States in the prior decade. Both were naturalized citizens. Jonsson was an only child. The family moved in 1912 to Montclair, New Jersey, where at the age of sixteen Jonsson graduated from Montclair High School. He was a graduate of Rensselaer Polytechnic Institute (RPI), class of 1922 earning a degree in mechanical engineering, where he was a member of Alpha Tau Omega. Jonsson married Margaret Fonde in Knoxville, Tennessee on 8 February 1923 and together they had three children. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

United States Army
The United States Army (USA) is the land service branch of the United States Armed Forces. It is one of the eight U.S. uniformed services, and is designated as the Army of the United States in the U.S. Constitution.Article II, section 2, clause 1 of the United States Constitution (1789). See alsTitle 10, Subtitle B, Chapter 301, Section 3001 The oldest and most senior branch of the U.S. military in order of precedence, the modern U.S. Army has its roots in the Continental Army, which was formed 14 June 1775 to fight the American Revolutionary War (1775–1783)—before the United States was established as a country. After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army.Library of CongressJournals of the Continental Congress, Volume 27/ref> The United States Army considers itself to be a continuation of the Continental Army, and thus considers its institutional inception to be th ...

Electronics
The field of electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons using electronic devices. Electronics uses active devices to control electron flow by amplification and rectification, which distinguishes it from classical electrical engineering, which only uses passive effects such as resistance, capacitance and inductance to control electric current flow. Electronics has hugely influenced the development of modern society. The central driving force behind the entire electronics industry is the semiconductor industry sector, which has annual sales of over $481 billion as of 2018. The largest industry sector is e-commerce, which generated over $29 trillion in 2017. History and development Electronics has hugely influenced the development of modern society. The identification of the electron in 1897, along with the subsequent invention of the vacuum tube which could amplify and rectify small ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eugene McDermott
Eugene McDermott (February 12, 1899 in Brooklyn, New York - August 23, 1973 in Dallas, Texas) was an engineer and geophysicist who co-founded Geophysical Service Incorporated (GSI) in 1930 and later its parent company Texas Instruments in 1951. One of his most widely acclaimed patented inventions was for oil exploration equipment, related to the early use of reflection seismographs, still widely used today in oil exploration to map underground rock strata using sound wave technology. Other inventions ranged from geochemical applications to antisubmarine warfare, often focusing on the use of sonar. Early life and career Born in Brooklyn, New York, McDermott graduated from Stevens Institute of Technology in 1919 with a mechanical engineering degree. Upon graduation, he began working for the Goodyear Rubber Company. In 1923, McDermott found work with Western Electric Company where he first met J. Clarence Karcher. Earlier, Everette Lee DeGolyer, vice president and general manager ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Petroleum
Petroleum, also known as crude oil, or simply oil, is a naturally occurring yellowish-black liquid mixture of mainly hydrocarbons, and is found in geological formations. The name ''petroleum'' covers both naturally occurring unprocessed crude oil and petroleum products that consist of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both prolonged heat and pressure. Petroleum is primarily recovered by oil drilling. Drilling is carried out after studies of structural geology, sedimentary basin analysis, and reservoir characterisation. Recent developments in technologies have also led to exploitation of other unconventional reserves such as oil sands and oil shale. Once extracted, oil is refined and separated, most easily by distillation, into innumerable products for direct use or use in manufacturing. Products include fuels such as gasol ...

Reflection Seismology
Reflection seismology (or seismic reflection) is a method of exploration geophysics that uses the principles of seismology to estimate the properties of the Earth's subsurface from reflected seismic waves. The method requires a controlled seismic source of energy, such as dynamite or Tovex blast, a specialized air gun or a seismic vibrator. Reflection seismology is similar to sonar and echolocation. This article is about surface seismic surveys; for vertical seismic profiles, see VSP. History Reflections and refractions of seismic waves at geologic interfaces within the Earth were first observed on recordings of earthquake-generated seismic waves. The basic model of the Earth's deep interior is based on observations of earthquake-generated seismic waves transmitted through the Earth's interior (e.g., Mohorovičić, 1910). The use of human-generated seismic waves to map in detail the geology of the upper few kilometers of the Earth's crust followed shortly thereafter and h ...

Geophysical Service Incorporated
Geophysical Service Inc. (often abbreviated GSI) was founded by J. Clarence Karcher, John Clarence Karcher and Eugene McDermott in 1930 for the purpose of using refraction and reflection seismology to Hydrocarbon exploration, explore for petroleum deposits. History On December 6, 1941, the company was purchased by Eugene McDermott, Cecil Howard Green, J. Erik Jonsson, and H.B. Peacock. During World War II, the company produced submarine detection devices. In 1951, the company was renamed Texas Instruments (TI) with GSI as a division. GSI was later sold by TI, repurchased, and finally sold again to Halliburton in 1988. Halliburton also acquired GeoSource, a competing geophysical contractor (formerly Petty-Ray Geophysical), and attempted to merge the two companies. Unfortunately the rivalry between the two entities endured and the merged entity known as Halliburton Geophysical Services (HGS) proved to be far from profitable. After several years of losses in 1994 Halliburton sold ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
