A German World War II refugee and recluse, Frank produced innumerable colorful, imaginative, hallucinogenic images of the universe inspired by scientific theories of the cosmos and his own explorations of the stars through his powerful studio telescope. After his death at the age of 62 in 1997, Frank’s sister Renata preserved his voluminous body of work—paintings on canvas of various sizes, and many works on paper—exactly as he had left it at the time of his death.
