⏹ Fleming, Sir John Ambrose
Fleming, Sir John Ambrose

English physicist and inventor (1849-1945)
He worked as a teacher of electrical engineering in London and worked in the study of electrical resistance at low temperatures. His most important achievement was the invention of the thermionic valve in 1904, which was the cornerstone of radio transmission technology. Fleming also contributed to the development of electric lighting and its lamps and left several valuable works.
۔ The first electronic valve made by Ambrose Fleming.

⏹ Finsen, Niels Ryberg

Danish physician and inventor of Icelandic origin (1860-1904)
Invented «Venzen lamp, ultraviolet light used in physical therapy. He was particularly interested in phototherapy, and it can be said that he laid the foundations for phototherapy.

⏹ Vinci, Leonardo da Vinci Leonardo da

Italian scientist, inventor and artist (1452-1519)
Vinci's basic education was art (painting and sculpture), but with his outstanding genius, he represented the ideal human being of the Renaissance, i.e. the human being capable of excelling in all fields. Therefore, Vinci was a poet, painter, engineer, scientist, architect, anatomist, and inventor with the same superiority.
Vinci worked in the service of the Duke of Milan, where he presented wonderful engineering and artistic designs. Then he joined the service of the Borgia family and the French royal family.
Although he did not have the full ability to express himself, his ideas were completely ahead of his time.
Developing water irrigation system designs for the plains of Lombardy, to the extent that it can be said that Vinci is the founder of hydraulics.
Among his basic designs are flying machines, rapid-fire cannons, a tank, and a hyperboloid. Vinci understood the importance of fossils in scientific research and was the first to explain the phenomenon of “the light of the earth on the moon.”
