Guillermo Kahlo was Frida Kahlo's father, born in Germany with debated Jewish/Hungarian or German ancestry. He moved to Mexico in 1891 and married Frida's mother Matilde Calderon y Gonzalez, a devout Catholic of indigenous Mexican and Spanish descent, after his first wife died. Frida was born in 1907 and at age 6 contracted polio. In 1925 she was in a devastating bus accident that left her disabled, after which she began painting to cope with pain. Her works reflected her physical and emotional suffering, as well as the turbulent relationship with her husband Diego Rivera, whom she divorced and remarried.
