Julius du Mont (15 December 1881, in Paris, France – 7 April 1956, in Hastings, England) was a pianist, piano teacher, chess player, journalist, editor and writer. He studied music at the Frankfurt Conservatoire and at Heidelberg, and became a concert pianist. He emigrated to England as a young man and became a successful piano teacher. Amongst his pupils was Edna Iles. He settled in London and also gained a reputation as a strong chess player. He won club and county chess championships in the period leading up to World War I, and showed his mastery of the English language by writing a manual on the Lewis gun. After the war, chess writing took up more and more of his time. Perhaps his most famous work was 500 Master Games of Chess (1952), written in collaboration with Savielly Tartakower.
For some years, du Mont was chess columnist of The Field and of the Manchester Guardian. Between 1940 and 1949 he was general editor of British Chess Magazine.
