According to Klimt's website, Bloch-Bauer was his mistress. She is also the only woman he ever painted twice. Adele's husband, Ferdinand Bloch-Bauer, hired Klimt to paint both paintings. Klimt painted "Portrait of Adele Bloch-Bauer I" in 1907 and "Portrait of Adele Bloch-Bauer II" in 1912. Some artists also think Adele Bloch-Bauer might be the woman in "The Kiss" and "Judith and the Head of Holofernes". The first portrait was a present from Ferdinand Bloch-Bauer to Adele's parents.
