Allvar Gullstrand

Allvar Gullstrand (1862 to 1930) was a Swedish ophthalmologist and optician, born at Landskrona, who received the Nobel Prize in Physiology or Medicine in 1911 for applying the methods of physical mathematics to the study of optical images and of the refraction of light in the eye. He was professor of eye therapy and then of optics at the University of Uppsala from 1894 to 1927, and is noted for his research on astigmatism and for improving the ophthalmoscope and the corrective lenses used after removal of a cataract. A member of the Royal Swedish Academy of Sciences from 1905, he served on its Prize Committee for Physics, where in 1921 he opposed a Nobel Prize for Einstein on his theory of relativity.
