The Scharrers and Hesses were not related and Irene and Myra were not cousins, as many people believed.

[3] Scharrer made her London début at the age of 16, and gave concerts regularly[4][5] until June 1958, where she appeared for the last time, playing Mozart's Sonata for Two Pianos with Myra Hess.

[9][10][11] Other collaborators included Arthur Nikisch in Berlin,[12] Hungarian violinist Louis Pecskai,[8] and Landon Ronald in London.

She visited Sir Edward Elgar in 1918 and was promised the first performance of his piano concerto, then being sketched.

Recorded repertoire included: Scharrer married Samuel Gurney Lubbock, who was a housemaster at Eton College.
