Hungarian composer and pianist (1811–1866) who takes a place among the first rank of nineteenth-century musicians. His superhuman prowess at the keyboard earned him a singular cachet as perhaps the greatest virtuoso in the history of the instrument. His advanced, forward-looking musical language made him one of the most important and influential composers of the Romantic era; in this regard, his primary benefactor was his son-in-law, Richard Wagner. Mailing envelope addressed in Liszt’s hand to “Madame Marie de Saar (née Liszt),” 4.5 x 3.75, postmarked Neustadt, no date. In fine condition, with notations in another hand, a few tears and small chips from opening (well away from writing), and scattered soiling. COA John Reznikoff/PSA/DNA and R&R COA.
