The journalist, essayist and historian Humberto Musacchio died on the night of November 4, 2026, at the age of 83, nine days after his birthday. The news was confirmed by Consuelo Sáizar, former head of the National Council for Culture and the Arts and the Fondo de Cultura Económica, according to Aristegui Noticias.

Born on October 26, 1943, in Ciudad Obregón, Sonora, Musacchio studied at the National School of Economics of the National Autonomous University of Mexico (UNAM), a degree he did not complete, and took part in the 1968 student movement. He devoted himself to journalism from 1969, after contributing to the cultural supplement of El Nacional. According to El Universal, he was responsible for the cultural pages of Unomásuno and for the supplements Comala and Hoja por Hoja. His work matters to Mexico because for more than five decades he documented the country's intellectual life in chronicles, dictionaries and columns that reporters, academics and students still consult today.

In 1971 he took over the cultural section of El Universal, a newspaper from which he was suspended after publishing two articles on the writer Martín Luis Guzmán, according to Aristegui Noticias. He also served as culture and news editor at Unomásuno, was a founder of La Jornada in 1984 and its deputy editor until 1985. He edited the supplement Comala, of El Financiero, and the magazines Kiosco and Mira, and for decades wrote the column La República de las Letras. His books include Alfonso Reyes y el periodismo (2006) and Historia del periodismo cultural en México (2007), as well as the Diccionario enciclopédico de México, published in four volumes in 1989 and reissued as Milenios de México between 1999 and 2000. In March 2026 he received the FILCO Tribute to Cultural Journalism.

The academic Sergio Aguayo remembered him as "a Mexican committed to democracy and human rights" and "a very loyal friend," in a message picked up by Aristegui Noticias. The Senate's Political Coordination Board expressed its condolences to the family, and Cultura UNAM highlighted his contributions to cultural journalism and the importance of La República de las Letras.

Condolences from cultural institutions, academics and legislators came in throughout the day, according to Aristegui Noticias. His body of work, with the Diccionario enciclopédico de México as its centerpiece, remains a reference for those who study the Mexican press and Mexican culture.
