Samuel Klingenstierna

Klingenstierna Samuel (* 1698 in Linköping, † 1765 ) was a Swedish physicist and mathematician.

Klingenstierna first studied law at Uppsala and was secretary of the Swedish Treasury, but was given permission his philosophical and scientific studies at the University of Uppsala to continue. 1727 he undertook with the help of a scholarship, a trip to Europe, among other things to Marburg to Christian Wolff and from Basel to Johann Bernoulli. It was after his return in 1728 professor of mathematics at Uppsala and in 1750 professor of physics. 1756 to 1764 he was a teacher of the Swedish crown prince.

He proved first of the inaccuracy of some of Newton's views on light refraction and designed lenses that were corrected for chromatic lens aberration and spherical aberration. His writings suggested in England at the optician John Dollond to similar investigations which led there to the first achromatic lenses ( 1758).
