thumb|right|325px|Friede made the first documentary about San Agustín in 1942 Juan Friede Alter (Wlava, Russian Empire, 17 February 1901 - Bogotá, Colombia, 28 June 1990) was a Ukrainian-Colombian historian of Jewish descent who is recognised as one of the most important writers about Colombian history, the Spanish conquests and a proponent of indigenism; the defense of the rights and descriptions of the oppression of indigenous people.

Juan Friede went to Colombia in 1926 for business and his fascination for the country, its climate and culture made him emigrate. He became a Colombian citizen in 1930. During the 1940s, Friede made extensive studies about various indigenous peoples in the country. He was a professor at the newly founded Department of Social Sciences of the National University of Colombia and is considered one of the pioneers of the "New History" movement in Colombia, together with Jaime Jaramillo Uribe, Luis Eduardo Nieto Arteta

and Luis Ospina Vásquez. His former house in San Agustín since 2006 bears the name Casa Museo Juan Friede.
