Cajori's A History of Mathematics (1894) was the first popular presentation of the history of mathematics in the United States.[6] Based upon his reputation in the history of mathematics (even today his 1928–1929 History of Mathematical Notations has been described as "unsurpassed")[7] he was appointed in 1918 to the first history of mathematics chair in the U.S, created especially for him, at the University of California, Berkeley. He remained in Berkeley, California until his death in 1930. Cajori did no original mathematical research unrelated to the history of mathematics.[6] In addition to his numerous books, he also contributed highly recognized and popular historical articles to the American Mathematical Monthly.[5] His last work was a revision of Andrew Motte's 1729 translation of Newton's Principia, vol.1 The Motion of Bodies, but he died before it was completed.
