While Olga Costa was German born and of Russian descent, she made a name for herself as a Mexican painter. Olga Costa was born Olga Kostakovsky in Leipzig, Germany. Costa spent her early childhood years in Berlin with her father, Jakob Kostakovsky, a known violinist. At the age twelve, Costa ventured to Mexico with her family who eventually settled in Mexico City. Costa met master painters Diego Rivera, Frida Kahlo and Rufino Tamayo and began her studies at the National School of Plastic Arts.

Costa married José Chávez Morado, a well-known painter in Mexico. Costa and Morado actively fought for social justice in Mexico. They were particularly active in their local community in Guanajuato, Mexico.

Costa’s many oil and gouache paintings are rich in Mexican imagery and technique. After traveling to Japan in the 1940s, Costa incorporated aspects of Japanese art and composition into her vibrant paintings of Mexico.

In 1945 Costa held her first individual exhibition in the Galería de Arte Mexicana. Costa is known today as one of the most important Mexican artists. Do you think you own a painting by Olga Costa? Contact us. We are the Costa experts.
