Cesar Julio Romero Jr. was born in New York City on February 15, 1907, the son of Cesar Julio Romero Sr. and Maria Mantilla. His mother was said to be the biological daughter of Cuban national hero Jose Marti. His father was born in Barcelona, Spain and immigrated to the United States in 1888, where he was an expert merchant in commercial business. His mother was a concert singer.
At 6'3", Romero routinely played "Latin lovers" in films from the 1930s until the 1950s, usually in supporting roles. He starred as the Cisco Kid in six westerns made between 1939 and 1941. Romero danced and performed comedy in the 20th Century Fox films he starred in opposite Carmen Miranda and Betty Grable, such as Week-End in Havana and Springtime in the Rockies, in the 1940s. He also played a minor role as Sinjin, a piano player in Glenn Miller's band, in the 1942 20th Century Fox musical Orchestra Wives.  In The Thin Man (1934), Romero played a villainous supporting role opposite the film's main star William Powell. Many of Romero's films from this early period saw him cast in small character parts, such as Italian gangsters and East Indian princes. Romero had a lead role as the Pathan rebel leader, Khoda Khan, in John Ford's British Raj-era action film Wee Willie Winkie (1937) and The Little Princess (1939) alongside Shirley Temple. He also appeared in a comic turn as a foil for Frank Sinatra and his crew in Ocean's 11 (1960).  Romero sometimes played the leading man, for example in Allan Dwan's 15 Maiden Lane (1936) opposite Claire Trevor, as well as winning the key role of the Doc Holliday character (with name changed to "Doc Halliday") in Dwan's Wyatt Earp saga Frontier Marshal three years later. 20th Century Fox, along with mogul Darryl Zanuck, personally selected Romero to co-star with Tyrone Power in the Technicolor historical epic Captain from Castile (1947), directed by Henry King. While Power played a fictionalized character, Romero played Hernan Cortes, a historical conquistador in Spain's conquest of the Americas.

When did Romero's career begin?

He starred as the Cisco Kid in six westerns made between 1939 and 1941.

Tristan Tzara (French: [tRista dzaRa]; Romanian: [tris'tan 'tsara]; born Samuel or Samy Rosenstock, also known as S. Samyro; April 16 [O.S. April 4] 1896 - December 25, 1963) was a Romanian and French avant-garde poet, essayist and performance artist. Also active as a journalist, playwright, literary and art critic, composer and film director, he was known best for being one of the founders and central figures of the anti-establishment Dada movement. Under the influence of Adrian Maniu, the adolescent Tzara became interested in Symbolism and co-founded the magazine Simbolul with Ion Vinea (with whom he also wrote experimental poetry) and painter Marcel Janco. During World War I, after briefly collaborating on Vinea's Chemarea, he joined Janco in Switzerland.
S. Samyro, a partial anagram of Samy Rosenstock, was used by Tzara from his debut and throughout the early 1910s. A number of undated writings, which he probably authored as early as 1913, bear the signature Tristan Ruia, and, in summer of 1915, he was signing his pieces with the name Tristan.  In the 1960s, Rosenstock's collaborator and later rival Ion Vinea claimed that he was responsible for coining the Tzara part of his pseudonym in 1915. Vinea also stated that Tzara wanted to keep Tristan as his adopted first name, and that this choice had later attracted him the "infamous pun" Triste Ane Tzara (French for "Sad Donkey Tzara"). This version of events is uncertain, as manuscripts show that the writer may have already been using the full name, as well as the variations Tristan Tara and Tr. Tzara, in 1913-1914 (although there is a possibility that he was signing his texts long after committing them to paper).  In 1972, art historian Serge Fauchereau, based on information received from Colomba, the wife of avant-garde poet Ilarie Voronca, recounted that Tzara himself had explained his chosen name was a pun in Romanian, trist in tara, meaning "sad in the country"; Colomba Voronca was also dismissing rumors that Tzara had selected Tristan as a tribute to poet Tristan Corbiere or to Richard Wagner's Tristan und Isolde opera. Samy Rosenstock legally adopted his new name in 1925, after filing a request with Romania's Ministry of the Interior. The French pronunciation of his name has become commonplace in Romania, where it replaces its more natural reading as tara ("the land", Romanian pronunciation: ['tsara]).

Why did he change his name?
Vinea also stated that Tzara wanted to keep Tristan as his adopted first name,
