Portuguese filmmaker António Lopes Ribeiro specialized in documentaries, both short and feature length, for theatrical release and television. Before entering the industry in the late '20s, Ribeiro was one of Portugal's first film critics, best known for his contributions to the Lisbon newspaper Diário de Lisboa where he wrote under the pen name of Retardor. Ribeiro made his first silent short, Uma Batida em Malpique/A Hunting Party in Malpique, in 1928 and afterward wandered across Europe visiting many film studios. In 1929, Ribeiro contributed Portuguese sequences to German director Eric Schönfelder's Fräulein Lausbub; he then turned to radio, working in the music department at the Emissora Nacional. Between 1944 and 1951, Ribeiro managed the Comediantes de Lisboa theater company. He began a sporadic television career in the late '50s and contributed to the long-running series Museu do Cinema/Museum of Cinema until its demise in 1974. During the Spanish Civil War, Ribeiro staunchly supported Salazar and made propaganda features and short documentaries on his behalf. During the 1940s, Ribeiro produced a few films through his own company.
