⏹ Harrington, Sir Charles Robert
Harington, Sir Charles Robert

English chemist ( 1897 - )
Harrington studied at Melvern College and Cambridge and worked as a professor of pathological chemistry at University College in London. Harrington conducted a lot of research in biochemistry and participated with Barger in the synthesis of thyroid extract (thyroxine) (see Kendall 1886). • Harrington published a book entitled The Thyroid Gland, its Chemistry and Physiology, 1933.
Harrington was made a Fellow of the Royal Society and served as Director of the National Institute for Medical Research.

⏹ Haldane, John Borden Sanderson
Haldane John Burdon Sanderson

English physiologist (1892-)
Haldane was educated at Oxford, then worked as a professor of biochemistry in Cambridge and then as a professor of genetics at University College in London. Haldane was made a Fellow of the Royal Society. He did many researches in the functions of organs and organic chemistry, and wrote a number of books in the fields of philosophy and science · Haldane left Britain at the age of fifty-nine, heading to India to work as a professor at the Indian Institute of Statistics in Calcutta.

⏹ Haller, Albrecht Von Haller

Swiss anatomist and physiologist (1708-1777).
Haller studied in Bingen and Leiden and then worked as a professor! for anatomy in Gettingen · He was distinguished by the breadth of aspects of effective knowledge, as he is a novelist and Felceren in addition to being a scientist. His works in the history of science were of particular importance • Among Haller's most important writings is a book entitled: Elements of the Physiology of the Human Body, Elementa ogiae Corpis Humani.
He published it in eight volumes between 1757 and 1766. This reference contains an explanation of Haller Kühl's hypothesis and archaeology, with a biological concept. He explained how muscle tissue contraction occurs when it falls under an external stimulus or stimulus. However, despite his superiority in this field, he carried some wrong opinions in embryology.

⏹ Halley, Edmund Halley,

British mathematician and astronomer (1656-1742)
Halley studied at Oxford, then went to Saint Helena Island to stay for two years, working on preparing a photographer for the stars that appear in the southern hemisphere. And he set a date for his return, and this was proven seventeen years after Haley's death, so it was the first prediction of its kind to prove its validity. Halley was the first to make a correct determination of stellar motion. In 11686 he published a map of the winds on the surface of the earth. He was the first to point out that the salinity of sea water results from the salts carried by rivers.
Halley and Isaac Newton were friends, and thus the book Principia was printed.
Which Newton composed at the expense of Halley. This book discusses the natural philosophy of the principles of mathematics.
Halley's comet (after Edmund Halley).

Hantzsch, Arthur Rudolph

German organic chemist (1857-1935)
Hansch studied in Dresden and Würzburg, then taught chemistry in Leipzig and taught in Zurich.
He conducted research on acids and on the ability of organic compounds to conduct electricity. Hantsch also studied the stereochemistry of nitrogen compounds.

⏹ Hahn, Otto

German physical chemist (1879-1968)
Han learned in Frankfurt, Marburg and Munich. He worked as an assistant for a short time with Ramsay in London and Rutherford at McFel University. He worked as a teacher in Berlin for a while, then went to the Short Wilhelm Institute of Chemistry, and soon Han became the director of this institute in 1928. Administrative scientific positions.
His achievements and studies on radioactive elements. He participated in some of them with Meitner. Han, in cooperation with Strassmann in 1938, was able to practically verify the nuclear fission of the uranium element by bombarding it with neutrons. Received the Nobel Prize for Chemistry in 1944 ·
