Joseph Haydn, Austrian composer, 1732 – 31 May 1809, was an Austrian composer, one of the most prolific and prominent composers of the Classical period. He is often called the "Father of the Symphony" and "Father of the String Quartet" because of his important contributions to these forms. He was also instrumental in the development of the piano trio and in the evolution of sonata form.
In addition to being the greatest jazz musician of the 20th century, Louis Armstrong was also the most beloved. “I never met anybody that didn’t love him that ever saw him work or ever has encountered him, had any connection or any business with him,” said Bing Crosby. Armstrong’s charm lay in his straightforward openness.
