Sedje Hémon (stage name Sedje Frank; Rotterdam, April 12, 1923 – The Hague, February 8, 2011) was an exceptionally versatile Dutch visual artist, violinist, composer, and music educator. Her work operates at the intersection of visual art and music, where experimentation, imagination, and craftsmanship were central.

Sedje Hémon developed a distinctive artistic signature in which sound, rhythm, and form reinforce each other. As a musician and composer, she was deeply rooted in the classical tradition, yet she did not shy away from experimentation. After a defining encounter with the legendary pianist Shura Cherkassky, she became a pioneer and champion of the pan flute within classical music—an instrument she introduced with conviction to a domain where it was rarely recognized.

In addition to her performing and creative practice, Hémon played a significant role as a music educator, inspiring generations of musicians with her open approach and groundbreaking vision. Her visual work echoes the same musical sensibility: compositions in which movement, harmony, and tension are palpable.

Sedje Hémon is one of those rare artists who doesn't juxtapose disciplines, but truly merges them. Her legacy lives on in both Dutch art history and in the innovative approach to instrumentation within classical music.
