Alfredo Zalce Torres (12 January 1908 – 19 January 2003) was a Mexican artist and contemporary of Diego Rivera, David Siqueiros and other better-known muralists. He worked principally as a painter, sculptor, and engraver, also taught, and was involved in the foundation of a number of institutions of culture and education. He is perhaps best known for his mural painting, typically imbued with "fervent social criticism". He is acclaimed as the first artist to borrow the traditional material of coloured cement as the medium for a "modern work of art". Publicity-shy, he is said to have turned down Mexico's Premio Nacional de Ciencias y Artes before finally accepting it in 2001. Before his death, Sotheby's described him as "the most important living Mexican artist up to date".
A number of episodes from his childhood have been used to cast light on his future artistic career. Born in Pátzcuaro, Michoacán in 1908, as an infant he lived in Tacubaya during the Mexican Revolution; his school was near where the rival forces of Victoriano Huerta and Emiliano Zapata met in battle. One day he saw a dead body; he says that instead of fear his attitude was that of contemplation. According to a friend and prominent collector of his works, the young Alfredo began to draw aged six or seven, but chose to do so upon the linoleum floor of his home; nevertheless both his parents praised him. While at primary school, he regularly drew on the blackboard to accompany his teachers and illustrate their lessons, as encouragement to his fellow pupils.
