Personal life and death As a homosexual with an active political sensibility, van Dantzig felt acutely the intolerance of his times, and this became a major theme in his ballets and his writings.

He died in an Amsterdam hospital from lymphoma and male breast cancer in 2012. He was 78 years old. Selected dance works 1955. Nachteiland (Night Island), music by Claude Debussy. 1958.
