Mario I. Gandelsonas (born December 14, 1937, in Buenos Aires, Argentina) is an Argentine-American architect and theorist whose specializations include urbanism and semiotics.
He was educated at the University of Buenos Aires where he received a Diploma Architect in 1962, and at the Centre de Recherche d’Urbanisme in Paris, from 1967 to 1968.
[1] In 1971, the American Architect Peter Eisenman invited Gandelsonas to travel to New York as a visiting fellow to the Institute for Architecture and Urban Studies(IAUS).

He published the results of his research in the book X-Urbanism (1999), presenting his theory on the relationship between architecture and the American City.
