Actor Carlos Rivas

Rivas was born in El Paso, Texas, to a German father and Mexican mother. English was his first language and he was also known as Oscar von Weber and Karl Weber.

Carlos Rivas was discovered in a bar in Mexico. He began his career in Mexican and Argentinian westerns, though his Argentinian films were actually filmed in Mexico.

His American debut was in The King and I (1956) opposite Rita Moreno. After this career highlight, he was quickly reduced to supporting roles. That same year of 1956 he appeared as Johnny Bravo in the TV western Cheyenne in the episode titled "Johnny Bravo," and in the 1961 episode of Maverick titled "Poker Face" starring Jack Kelly. Rivas had co-starring roles in two science fiction films, The Beast of Hollow Mountain (1956) and The Black Scorpion (1957). Rivas played Chingachgook in The Deerslayer (1957) with Lex Barker, Forrest Tucker, and Rita Moreno.

In 1970, Rivas joined Ricardo Montalbán, Henry Darrow, and other Latino actors in co-founding the Nosotros ("We") Foundation, a Los Angeles based organization devoted to improving the way Hispanics are depicted in entertainment and to advocating for Latinos in the movie and television industry.^{[citation needed]}
