⏹ Henderson, George Gerald
Henderson, George Gerald

Scottish chemist (1862 - 1942)
Henderson learned in Glasgow and Leipzig, then returned to his country, Glasgow, to work as a professor of chemistry in 1919. He conducted research on catalysts, and discussed other chemical issues.
Henderson was made a Fellow of the Royal Society. One of Henderson's most prominent studies was what he had done on organic and inorganic materials and catalysts.

⏹ Henry, Joseph Henry, Joseph

American physicist (1797 - 1878)
Henry began his working life as an apprentice at a watchmaker. Then he turned to the study of natural sciences to become a professor of natural sciences at Princeton University in the years 1832-1848.
His works focused primarily on the electro-magnetic phenomenon, as well as acoustics and meteorology. In 1829, Henry built the first electromagnetic motor. He made important developments and improvements to electromagnets at the same time that Faraday was working on them. And discover a way to produce inductive currents (influence). In the field of electrical experiments, he discovered the basis on which electromagnetic lightning is based and invented two types of flavonometers, namely: low-resistance and high-resistance flavonometers. He also revealed the oscillatory nature of electric charge. Henry also studied solar radiation and sunspots. And he was the first to start issuing and organizing climate reports “the weather reports system, or the weather forecast system.” Henry held the position of director and director of the Smithsonian Institution.
And his name was elected in 1915 to be in the American Hall of Fame · It is named after the unit of electromagnetic inductance.
Henry = volts x seconds over amperes x fibers over amperes.
General view of a large electromagnet designed by Henry.

⏹ Henry, William Henry, William

English chemist (1775 - 1836)
Henry studied medicine in Edinburgh, practiced it in Manchester, and then his poor health prompted him to leave medicine. He devoted his time to the study of chemistry, and his father was related to chemical matters. Henry was chosen as a fellow in the Royal Society, and he was awarded the Copley Medal in 1809.
Henry developed a chemical law that bears his name and stipulates that the amount of dissolved gas in a liquid is proportional to the gas pressure when the temperature is constant.

⏹ Hensen, Victor

German physiologist
( 1924-1835 )
Henson's fame was based on his founding of a new branch of biology (biology) based on the study of wandering plants, which are simple plants that live wandering in water that is moved by waves from one place to another. He named these plants plankton, and he conducted a lot of research on their reproduction and spread.

⏹ Hench, Philip Shaw Walter Hench, Philip

American doctor ( 1896 - )
Hensch learned at Lafayette College, then studied medicine in America and Germany.
(See Mayo) in 1926.
Hench shared with Kendall and Reichstein the Nobel Prize for Medicine in 1950, for his contribution to the discovery of cortisone, a hormone produced by the cortex of the adrenal glands (suprarenal). It is used to treat rheumatism, in addition to many other medicinal benefits.
