Scientists born on June 4

Robert F. Furchgott

Born June 4, 1916; Died May 19, 2009 at the age of 92.
Robert Francis Furchgitt was an American pharmacologist who shared the 1998 Nobel Prize in Physiology or Medicine (along with Louis J. Ignacio and Fred Murad) for his discovery that nitric oxide (NO) acts as a signaling molecule in the cardiovascular system. Is. Their joint work revealed a brand new mechanism by which the blood vessels in the body relax and dilate. Nitric oxide (NO), produced by a cell, works by penetrating membranes and regulating the function of other cells. Nerves and hormones are known as signal carriers, but this discovery was a completely new signaling principle in the biological system.

Sir Christopher Cockerell

Born June 4, 1910 Died June 1, 1999 at the age of 88
The English inventor of the hovercraft. He was an electronics engineer at the Marconi Company (1935-50) where he worked on aircraft carriers and radar. Then he started a boat rental business. While contemplating pulling water on the hull of the boat, he came up with the idea of ​​lifting the boat on a cushion of air. In 1954, he conducted a major experiment using kitchen scales, tin cans and a vacuum cleaner to show that airflow could produce the desired lift. The following year, he developed a model of the Varsa Balsa wood with a model aircraft engine. The first full-scale prototype, the SR-N1, weighed 7 tons and had a capacity of 60 bales. He crossed the English Channel in 1959 (with Rider Cockrell). Hovercraft entered regular cross-channel service in 1968.

Beno Gutenberg

Born June 4, 1889 Died January 25, 1960 at the age of 70
The US seismologist provided information on the analysis of seismic waves and the physical properties of the Earth's interior properties. Together with Charles Richter, he developed a method for determining the magnitude of earthquakes. Calculating the energy released by the current shallow earthquakes, he said that three-quarters of this energy is located in the Pacific Ocean belt.

Eliot Blackwelder

Born June 4, 1880 ؛ Died January 14, 1969 at the age of 88
American geologist who has made significant contributions to the field of geomorphology, particularly in the Rocky Mountains, the desert landscapes in Sierra Nevada and China, and the beginnings and evolution of mountain glaciation research.
Black Welder was an early proponent of the idea that the Arizona-based Meteor was indeed influential for Carter. After a short stint at other universities, he became professor of geology at Stanford University until his retirement (1922-45). He served for a time as President of the Geological Society of America in the offices he held, along with various other offices. He is the father of biologist Richard E. Black Welder.

Heinrich Otto Wieland

Born June 4, 1877 Died August 5, 1957 at the age of 80.
The German chemist was awarded the 1927 Nobel Prize in Chemistry for his study of steroid chemistry, in which he determined the molecular structure of bile acids. He is also known for his study of energy conversion in food. In 1912, he began work on bile acids, the secretion of the liver, known for the best part of a century, which contains a large number of substances. He studied three of them: choic acid, deoxycholic acid, and Lithocholic acid, which showed that they were all closely related steroids, and could all be converted into clinic acid. Were After 1921, he studied some curious alkaloids, including toxiferin (active ingredient in curry), bufotalin (poison from toads), and phalloidine and amethyst (toxic ingredients in the deadly amanita mushroom).

Jean Einstein Claude Chapel

Born June 4, 1756 Died July 30, 1832, at the age of 76.
French chemist who is the author of the first book on industrial chemistry. It also developed the name "nitrogen". Its technical activity covered a wide field, such as improving the preparation of sulfuric acid, salt pot for gunpowder, beet sugar, wine, dyeing, bleach and other things. He was the first to produce sulfuric acid commercially in France at his factory in Montpellier. His career covered the stormy period of the French Revolution. He was arrested, but more fortunate than Antoine Lavoisier (who was Gultoin), was later released to manage Salt Peter's affairs in Granille. He also helped introduce the matriculation system.

Franz Zeur von Zach

Born June 4, 1754 Died September 2, 1832, at the age of 78.
 German Hungarian astronomer under the patronage of Duke Ernst of the saxe Gotha Altenberg. Director of Observatory near  Gotha. (1787-1806) There he hosted the first Congress of Astronomers in 1798 with Joseph Lalande (1732-1807) as a special guest. In the last years of the 18th century, he formed a group of 24 European astronomers to search for a "missing" planet between the orbits of Mars and Jupiter, where they found the asteroid instead.

John Beckman

Born June 4, 1739 Died February 3, 1811 at the age of 71
German chemist and economist who founded the science of agriculture. He published a distinguished textbook (1769) that laid the scientific foundations of practical agriculture, including natural history, minerals, physics, chemistry and mathematics. Until 1769, he was using the word "technology", which he coined for the science of commerce. From his educational journey (1765-66), he had a good background in the manufacture of natural products and in the mining of metals, inspecting factories, mines and foundries. He published the first pioneering textbook (1777) which described the systematic preparation of raw materials in various trades. With its influence, a technical curriculum was introduced in secondary schools.

Benjamin Hunter

Born June 4, 1704 He died on June 20, 1776 at the age of 72.
The English inventor who invented the most important method of producing fine or tool steel (c.1740) with a homogeneous alloy enabled the production of steel on a commercial scale. This solved the problem of irregular quality of imported blister steel. Huntsman's steel was extremely hard, with great hardness and toughness. He prepared fire-proof clay for his crucifixes. The site he chose for his factory was the city of Sheffield, now known for centuries as a major manufacturing center for steel products. The first crucible steel was made for small items, including parts used in its watchmaking business, which may have influenced its invention. Its watchmaking continued until 1751, when he began full-time steel production.
