Guillermo Tovar de Teresa was a Mexican historian and an art collector, bibliographer, philanthropist, cultural promoter, and scholar. He was a constant defender of the historical and artistic Mexican heritage, mainly from his hometown, of which he was chronicler, an appointment that was originally in charge of the Presidency and to which he resigned to propose the creation of the Council of the Chronicle of the City of Mexico. He was a specialist in the New Spain/Mexican colonial period art, history and literature. He published several books about Colonial Mexican art and collaborated, among others, for the newspaper La Jornada. He stood out for his early intelligence: he learned to read long before entering school, and at age 13 he was advisor to colonial art of the then president Gustavo Díaz Ordaz. At 23, he published his first book, Renaissance painting and sculpture in Mexico. He was a member of the Historical Center Executive Committee, corresponding member of the Royal Academy of Fine Arts of San Fernando, in Madrid, and honorary member of the Hispanic Society of America, the latter based in New York City. He was considered a candidate for the Aesthetic Research Institute of the National Autonomous University of Mexico, but never wanted to hold a public office or receive any salary. One of his brothers, Rafael Tovar y de Teresa, was since 2012 the head of National Council for Culture and the Arts and first secretary of Culture. His house became, in December 2018, a museum, and is part of the Soumaya Museum.
