Arturo Toscanini (March 25, 1867 – January 16, 1957) was an Italian conductor. One of the most acclaimed musicians of the late 19th and 20th Centuries, he was renowned for his brilliant intensity, his restless perfectionism, his phenomenal ear for orchestral detail and sonority, and his photographic memory. He is especially regarded as an authoritative interpreter of the works of Verdi, Beethoven, Brahms and Wagner. As music director of the NBC Symphony Orchestra he became a household name through his radio and television broadcasts and many recordings of the operatic and symphonic repertoire.
Vladimir Samoylovich Horowitz (October 1, 1903 – November 5, 1989) was a Russian-American classical pianist and minor composer. His technique and use of tone color and the excitement of his playing were and remain legendary. He is widely considered one of the greatest pianists of the 20th century.
Horowitz was the Sin-In-Law of Toscanini.
