Samuel Klingenstierna
Samuel Klingenstierna (born August 18, 1698 in Linköping , † 1765 ) was a Swedish physicist and mathematician.
Life
Klingenstierna initially studied law in Uppsala and became a secretary in the Swedish Treasury, but received permission to continue his philosophical and scientific studies at Uppsala University. In 1727, with the help of a scholarship, he undertook a trip to Europe, including to Marburg to see Christian Wolff and to Basel to see Johann I Bernoulli . After his return in 1728 he became professor of mathematics in Uppsala and from 1750 professor of physics. He was rector of the university three times (1737, 1742 and 1749) . From 1756 to 1764 he was the teacher of the Swedish Crown Prince. In 1730 he became a Fellow of the Royal Society . In 1744 he was accepted as a corresponding member of the Académie des Sciences in Paris.
He was the first to prove the flawedness of some of Newton's views on refraction and engineered lenses corrected for chromatic lens aberration and spherical aberration . His writings inspired the optician John Dollond in England to carry out similar investigations, which led to the first achromatic lenses there (1758).
