Ahlgrimm, Isolde, eminent Austrian fortepianist, harpsichordist, and pedagogue; b. Vienna, July 31, 1914.

In 1935 she attracted notice at the Hamburg International Music Festival. After making her recital debut as a fortepianist in 1937, she taught herself to play the harpsichord and subsequently concentrated on both instruments. From 1937 to 1956 she was active with the Concerte fur Kenner und Liebhaber in Vienna; was also first prof. of harpsichord at the Vienna Academy of Music (1945^9). After teaching at the Salzburg Mozarteum (1958–62), she made her first visit to the U.S. in 1962 at the Oberlin (Ohio) Coll.
