Life

Cajori was the son of a road engineer. He attended school in Zillis and Chur and moved to the United States at the age of 16 in 1875 , where he attended school in Whitewater, Wisconsin , in 1876 . He then worked for a while as a village school teacher before studying at the University of Wisconsin (Bachelor 1883). After a year and a half at Johns Hopkins University , he made his master's degree from the University of Wisconsin in 1886. In 1885 he was Assistant Professor of Applied Mathematics at Tulane University in New Orleans . From 1889 to 1898 he was a physics professor at Colorado College in Colorado Springsand then until 1918 mathematics professor. He received his PhD from Tulane University in 1894. From 1918 he was a professor at the University of California, Berkeley on a specially created chair for the history of mathematics. Before his death he started a new translation of Newton's Principia .

Cajori was considered one of the leading mathematical historians of his time and was the first professor of mathematical history in the United States. Today he is best known for his book on the history of mathematical notation. In 1908 he contributed with the contribution arithmetic, algebra and number theory from 1759 to 1799 in the 4th volume of Moritz Cantor's lectures on the history of mathematics .

From 1917 to 1918, Cajori was President of the Mathematical Association of America (MAA). In 1921 he was elected to the American Academy of Arts and Sciences . In 1923 he was Vice President of the American Association for the Advancement of Science , 1924/5 of the History of Science Society and 1929 to 1930 of the International Committee for the History of Science . He was a three-time honorary doctor.

He was married from 1890 and had a son.

In 1970 the lunar crater Cajori was named after him.
