(b Buenos Aires, 23 Nov. 1862; d Buenos Aires, 17 June 1952). Argentine composer and pianist. He studied in Buenos Aires and in 1882 won a scholarship to the Paris Conservatoire, where he studied composition with Franck and the piano with Georges Mathias. On his return to Argentina in 1889 he earned his living as a concert pianist and began to explore the traditional music of his native land; the piano piece El rancho abandonado (1890) was the first of a number of works in which he incorporated folk tunes. Williams played a major role in Argentine musical life, founding a conservatory (1893) and several concert societies in Buenos Aires. His output includes nine symphonies, three violin sonatas, and 75 songs.
