Gustave Rudler (11 January 1872 – 17 October 1957) was a French scholar and academic, who served as the first Marshal Foch Professor of French Literature at the University of Oxford from 1920 until 1949.
Gustave Rudler was born in Besançon, France; his father taught at the local lycée.
For his doctoral thesis of 1908, for which he was directed by the scholar Gustave Lanson, he studied the French-born writer and academic Benjamin Constant, and the result was regarded as a major contribution to scholarship relating to Constant.
After a period teaching at the Sorbonne, Rudler moved to Bedford College (now part of Royal Holloway, University of London) in 1913 as professor of French.
Apart from military service during the First World War, he spent the remainder of his academic life in England.
