The very first image that you’ll see is quite historic: it’s that last performance that Lehmann sang in Europe. Fittingly, it was a Liederabend in Vienna, with Bruno Walter at the piano. Lehmann left shortly thereafter. Notice the many Carnegie Hall performances, mostly with the New York Philharmonic.
Also on this page are many reviews that Lehmann’s pianist Paul Ulanowsky clipped while on their first Australian tour in 1937. You can click on any of these images to see them larger. After those, there are many clippings, posters etc. gathered by Peter Clausen, the grandson of one of Lehmann’s colleagues, Bauer von Pilecka.
