Frida Kahlo was a Mexican painter, perhaps best known for her intensely personal self-portraits. She has become a prominent icon of Mexican national and indigenous tradition and is celebrated by feminists for her uncompromising lifestyle, as well as her artistic depiction of the female form and experience. 
"She is, however, an uneasy fit for Mexican culture. In this country dominated by tradition and Catholicism, she was an atheist communist (in and out of the party); in a land still gripped (say it: held back) by paternalism and machismo, she was her own woman and often her own man. She took on a more-Mexican-than-Mexicans identity, yet she was the daughter of a German immigrant who married a Mexican woman."
In a passage from a poem to husband, Diego Rivera, Kahlo writes:
Kills me, making
of your memory.
You are the nonexisting

Her father, Guillermo Kahlo, was an atheist (Frida: A Biography of Frida Kahlo (pp. 6) by Haden Herrera) and her husband, Diego Rivera, was also an atheist.
