Mildred Couper, American 1/4-tone pioneer.

Greta Couper, Mildred Couper's granddaughter, has informed me that a collection
of sheet music and some cassette recordings of her grandmother's compositions is
available at http://geocities.com/sanbarart/couper-m/music.htm. A number of her
compositions are for two pianos tuned a 1/4-tone apart.

Fantastic, John! Wow, at long last, the story of Mildred Couper! All of her
quartertone music was for pianos so a special edition should be set up, I
should think. This is a great find.
