Lilián Hedwig Elisaveth Welkery Gundlach, known as Lilia del Valle, was a Mexican actress born in Mexico City on April 30, 1928. She was the daughter of German immigrants and, along with her younger sister, began her primary education at the German School in Mexico City. The family later spent two years in Berlin, where the girls became fluent in German. Upon returning to Mexico, Lilia continued her studies while also taking painting lessons at the academy of Spanish artist José Bardasano, encouraged by her parents.
Her rise to stardom was swift. She acted alongside Víctor Parra, Roberto Cañedo, Blanca de Castejón, and Jorge Mistral. Although she began with dramatic roles, she found her greatest success in comedy. Some of her notable films include Las tres alegres comadres (1952) and Las interesadas (1952), where she shared the screen with Amalia Aguilar and Lilia Prado; Mis tres viudas alegres (1953) and Las cariñosas (1953), where Silvia Pinal replaced Prado; and Nadie muere dos veces (1953), alongside Luis Aguilar and Abel Salazar. She also starred in Esposas infieles (1956) with Columba Domínguez and worked with the famous comedian Germán Valdés "Tin Tan" in El bello durmiente (1952) and La isla de las mujeres (1953). One of her most challenging roles was in La bruja (1954), where she had to endure long hours in makeup. In this film, she starred alongside Ramón Gay, a major leading man in Mexican fantasy cinema.
In addition to her film career, Lilia performed in theater and toured extensively as a singer, accompanied by a trio. After filming Secuestro en Acapulco (1963), she decided to step away from acting to focus on her personal life. She only returned briefly for a special appearance in La recta final (1966), directed by Carlos Enrique Taboada. Over the years, she married three times and had a son, Marco Antonio Sánchez Welker.
On January 7, 2013, Lilia del Valle passed away in the Dominican Republic at the age of 84.
