Guillermo Graetzer's impact on my generation of young Jewish immigrants (with intellectual and artistic pretensions) is barely measurable. I remember his Sunday morning 'seminars' at the home of the pianist Jascha Galperin. I still have vivid memories of his detailed exposition of Mathis deer Mahler by Hindemith, with whom I believe Greatzer had studied. I must admit that presence of Jascha's daughter Lucy (a.k.a. Olga) had a magnetic effect on the attendance of the young mails, my own included. In any event, we all, and I believe my old friend Christophe Stegmann was part of the group, had our musical knowledge highly enhanced by Greatzer's articulate and interesting didactic effort.
In gratitude, Henry Raymont, Washington, D.C. (while listening to Hindemith's Mathis der Mahler (with Ormandy and the Philadelphia).
