Who is the greatest person in Chile?

I am not sure who is the most important person in Chilean history, it brings to my memory some names like presidents, artists, scientists, famous peoples and other more. But I have to choose one of them, so I think Violeta Parra is one of the women important, especially to Arts of Chile. She was an artist of the twentieth century in this country, she worked like composer, musician, folklorist and in other areas of traditions and popular customs. She was born in 1917 in a town of the south central Chile, then at age around 14 years she went to Santiago to study, but she left the school with the intention to dedicate to sing in different scenaries. With the pass of years she was mother of four children, two of them: Isabel and Angel, some time later were importants musicians of national folklore like was Violeta. Her work is known in many countries on the world, an example in 1964 she exposed at Louvre Museum in Paris with her visuals works, the first Latin American woman who did it, and she wrote many songs which times after were listened abroad.
She had a love with a foreign man who left her, and according the popular words maybe for this reason she took her life in 1967. I would like to ask her, if possible, why she decided to do that action. About her legacy, she revived and compiled much of popular traditions of the rural places in Chile expressed in the music, about that the most famous of Violeta's songs is Gracias a la Vida, which has been played by many national and international artists.
