district, with his second wife, the Austrian photographer Renate Graf, and their two children. Kiefer and Graf divorced in 2014. In 2017, Kiefer was ranked one of the richest 1,001 individuals and families in Germany by the monthly business publication Manager Magazin. Artistic process Generally, Kiefer attributes traditional mythology, books, and libraries as his main subjects and sources of inspiration. In his middle years, his inspiration came from literary figures, namely Paul Celan and Ingeborg Bachmann. His later works incorporate themes from Judeo-Christian, ancient Egyptian, and Oriental cultures, which he combines with other motifs. Cosmogony is also a large focus in his works. In all, Kiefer searches for the meaning of existence and "representation of the incomprehensible and the non-representational." Philosophy Kiefer values a "spiritual connection" with the materials he works with, "extracting the spirit that already lives within [them]." In doing so, he transforms his materials with acid baths and physical blows with sticks and axes, among other processes. He often chooses materials for their alchemical properties—lead in particular. Kiefer's initial attraction to lead arose when he had to repair aging pipes in the first house he owned. Eventually, he came to admire its physical and sensory qualities and began to discover more about its connection to alchemy. Physically, Kiefer specifically likes how the metal looks during the heating and melting process when he sees many colors, especially gold, which he associates to the symbolic gold sought by alchemists. Kiefer's use of straw in his work represents energy. He claims this is due to straw's physical qualities, including the color gold and its release of energy and heat when burned. The resulting ash makes way for new creation, thus echoing the motifs of transformation and the cycle of life. Kiefer also values the balance between order and chaos in his work, stating, "[I]f there is too much order, [the piece] is dead; or if there is much chaos, it doesn't cohere." In addition, he cares deeply about the space in which his works reside. He states that his works "lose their power completely" if put in the wrong spaces. Work Photography Kiefer began his career creating performances and documenting them in photographs titled Occupations and Heroische Sinnbilder (Heroic Symbols). Dressed in his father's Wehrmacht uniform, Kiefer mimicked the Nazi salute in various locations in France, Switzerland and Italy. He asked Germans to remember and to acknowledge the loss to
