What year did the scientist, who is the namesake of the Tyndall Center, die?
John Tyndall John Tyndall FRS (2 August 1820 – 4 December 1893) was a prominent 19th-century Irish physicist. His initial scientific fame arose in the 1850s from his study of diamagnetism. Later he made discoveries in the realms of infrared radiation and the physical properties of air. Tyndall also published more than a dozen science books which brought state-of-the-art 19th century experimental physics to a wide audience. From 1853 to 1887 he was professor of physics at the Royal Institution of Great Britain in London.
John Olney John Olney (1932April 14, 2015) was a medical doctor and a professor of psychiatry, pathology, and immunology at the Washington University School of Medicine. He is known for his work on brain damage. He coined the term excitotoxicity in his 1969 paper published in "Science". Olney's lesions are named after him. In 1996 he was elected to the Institute of Medicine of the United States National Academy of Sciences. He had campaigned for greater regulation of monosodium glutamate (MSG), aspartame and other excitotoxins for over twenty years. He died at his residence on April 14, 2015 at the age of 83.
