Richard Baer was born in Basel on September 11, 1892, the son of the banker Julius Baer . At the age of five he moved with his family from Basel to Zurich. After completing his graduation in 1912 bear an early interest in went Mathematics and Physics showed the age of 20 years at the University of Würzburg in order there to study mathematics . After the beginning of World War I , he finally returned from Würzburg to Zurich, Switzerland, to continue his studies at the University of Zurich and the Zurich University of Applied Sciences. Shortly afterwards he went back to Würzburg, where he received his doctorate from Emil Hilb in 1915 with his thesis on Green's boundary value problems in the oscillation equation. Soon afterwards he began his first scientific experiments in Professor Wilhelm Wien's laboratory .

At the end of 1916 he finally went to the Georg-August-Universität Göttingen to work as an assistant to the mathematician David Hilbert . In 1917 he went back to Zurich to continue working on his experiments in the field of experimental physics under Professor Edgar Meyer . In the following he mainly worked on his habilitation thesis . In 1918 he presented the first findings of his research to the Swiss Physical Society . In 1921 he presented further research results to the German Natural Scientists' Assembly in Jena . At the age of 30 he finally received the license to teach as a professor at the University of Zurich. In August 1922, Bär married Ellen Lohnstein from Worms . Four months later, in December 1922, after the death of his father Julius Baer, ​​Richard Baer also took a share in the Julius Baer bank, which his father had founded, with a limited liability of 500,000 Swiss francs .

A year later, in 1928, Bär became an adjunct professor . In the following he also advocated fleeing German-Jewish professors to continue their work abroad. He was also a co-founder of the scholarship fund for Jewish students in Switzerland . Subsequently, he met other important scientists such as Albert Einstein , Max Planck , Hermann Weyl , Irène Joliot-Curie , Chaim Weizmann and CV Raman . When CV Raman also discovered Raman scattering in 1928 , Richard Bär was interested in researching Raman's discovery until 1933. In 1930 his second daughter, Ruth Irene, was born. Seven years later, his second son, Thomas August, was born in 1937. After World War II broke out in 1939 , Richard Bär and his family planned to flee to the United States at Christmas 1940 . He wanted to continue his scientific research at the Institute for Advanced Study in Princeton (New Jersey) founded by Albert Einstein, Hermann Weyl and other emigrated scientists .

However, Bär, who at this point was terminally ill, died shortly before he was about to leave, on December 13, 1940 at the age of 48 in Zurich. Shortly thereafter, his wife, Ellen Bär-Lohnstein, moved to the United States with their children, where they arrived in May 1941, and subsequently kept in contact with scientists who had also emigrated. So it came about that a few years later, in 1950, she became the wife of Hermann Weyl.
