Emmy Heil Frensel-Wegener (14 June 1901 in Amsterdam – 11 January 1973 in Laren (North Holland) was a Dutch violinist, pianist, poet and composer.
Wegener was the daughter of composer Bertha Frensel Wegener-Koopman and American insurance agent John Frensel-Wegener.
[2] She also studied composition with Sem Dresden,[3][4] clarinet with Willem Brohm and Gregorian chant.
In 1934 she served on the jury for the evaluation of vocal quartet a cappella compositions for the Dutch Association for Contemporary Music, along with Hendrik Andriessen, Henk Badings, Anthon van der Horst and Daniel Ruyneman, but the jury awarded no first prize, finding no "composition of exemplary meaning" among the 47 submissions.
Wegener composed works for orchestra, chamber ensemble, piano and voice, which The New Grove described as "in a dissonant, neo-classical style."
