Alberto de Almeida Cavalcanti (February 6, 1897 – August 23, 1982) was a Brazilian-born film director and producer.
Cavalcanti was born in Rio de Janeiro, the son of a prominent mathematician. He was a precociously intelligent child, and by the age of 15 was studying law at university. Following an argument with a professor he was expelled. His father sent him to Geneva, Switzerland on condition that he did not study law or politics. Cavalcanti chose to study architecture instead. At 18 he moved to Paris to work for an architect, later switching to working on interior design. After a visit back to Brazil he took up a position at the Brazilian consulate in Liverpool, England.
Cavalcanti corresponded with Marcel L'Herbier, a leading light in France's avant-garde film movement. This led to a job offer from L'Herbier for Cavalcanti to work as a set designer.
In 1920 Cavalcanti left his job at the Consulate and moved back to France to work for L'Herbier; he was to be involved in the making of numerous films, the most notable being L'Inhumaine. He was soon making his own films, in 1926 directing his first, Rien Que les Heures (Nothing But Time) — a day in the life of Paris and its citizens. In 1927 he collaborated with Walter Ruttmann on a similar project set in Berlin, called Berlin: Die Sinfonie der Großstadt (Berlin: Symphony of a Big City). Cavalcanti took a job with Paramount's French studios after the talkies came in, but he found himself making more commercial films which could not hold his interest and left Paramount in 1933.
