Henkemans was one of the most important Dutch composers of his time. From 1926 to 1931 he studied piano and composition with Bernhard van den Sigtenhorst Meyer, and from 1933 to 1938 with Willem Pijper. Later he studied piano with George van Renesse. Henkemans was influenced by Claude Debussy, Maurice Ravel and Willem Pijper.
From 1931, Henkemans studied medicine at the University of Utrecht. In 1981 Henkemans analyzed the creative process in the textbook Sublimatie-stoornissen bij kunstenaars [Sublimation disorders in artists] (Deventer, 1981).
