After Idil graduated from the Paris Conservatory she went for the first time to Kempff’s home in Ammerland (near Munich) and worked with him for a week. At the end of her stay Kempff gave Idil the book «Auf den Lebenswegen Johann Sebastian Bachs» and wrote the following in the book: “Meinen lieben Idil, meiner genialen Schülerin, zur Erinnerung an die Tage in Ammerland. Wilhelm Kempff 2-7 Juni 1958” [My dear Idil, my genious pupil, in memory of the days in Ammerland.]
