An obituary on Wednesday about the violinist Roman Totenberg repeated an error from a 1935 Times report on a concert in Washington at which Mr. Totenberg made his United States debut. He performed Beethoven’s Violin Concerto in D Major — not in D Minor. (There is no such Beethoven violin concerto.) And the obituary misstated the surname of the pianist in the Alma Trio, which also included Mr. Totenberg and the cellist Gabor Rejto. He was Adolph Baller, not Bailer.
