Born in Lisbon, April 18th.

Attends the Physicochemical Sciences course at the Faculty of Sciences of Lisbon until 1942 but quits the bachelor's degree during the last year.

Begins his photographic production with captures of ethnographic details, popular art and sculpture, and portraits in urban contexts. In this decade his interest in the arts and in the study of popular art becomes evident.

Organizes a comparative exhibition between Modern Art and African Art during the Black Art Week at Escola Superior Colonial in Lisbon, the first of its kind in Portugal. Meets Almada Negreiros. This artist from the first generation of Portuguese Modernists becomes a steady reference from the 60s onwards, a starting point for the mixed medias Nós Não Estamos Algures and Almada, Um Nome de Guerra, and a central figure in his proposals for a new Portuguese avant-garde.

Becomes a regular collaborator at Seara Nova at the invitation of Fernando Lopes Graça. In this decade, his regular critique in this magazine, and others such as Mundo Literário, Portucale and Vértice, make him an influent defender of the neorealist movement. From the 1970s onwards, he will consider the avant-garde as the main successor of the neorealist project of an art that is participatory and necessary to transform the social context.

Founds and promotes Círculo de Cinema, one of the first film societies in Portugal. The society was closed down in 1948 by the PIDE [International Police and State Defence] with the arrest of members of the club, himself included.

Editor in chief at magazine Imagem until it closes in 1961. In this magazine his texts defend and settle the principles of the New Cinema [Novo Cinema]. The promotion of the film society movement in this magazine along with his active involvement in associative meetings, make him one of the most prominent film club members.

Organizes an African Art exhibition for the African Art and Folklore Week at Clube University de Jazz in Lisbon.

Dom Roberto premieres on May 30th at Cinema Império in Lisbon. The film is a turning point for the Portuguese cinema and is a forerunner of the New Cinema that would consolidate over the years following its premiere.
For about two years Ernesto de Sousa commits himself to promoting the film in Portugal and abroad.

Travels through Morocco and Algeria while the latter proclaimed its independence, in September and October, on his way to the Mannheim festival for a screening of Dom Roberto. The series of chronicles Cartas do Meu Magrebe resulted from this journey and was published this year and the following in Jornal de Notícias.
