I have a test where I am given the following article, what is an answer for the question: What was the full name of the school Sir Alexander Mackenzie was principal of? ?  Giovanni Battista Barbirolli was born in Southampton Row, Holborn, London, the second child and eldest son of an Italian father and a French mother. He was a British national from birth, and as Southampton Row is within the sound of Bow Bells, Barbirolli always regarded himself as a Cockney.

McEwen and the cello with Herbert Walenn. In 1914 he was joint winner of the academy's Charles Rube Prize for ensemble playing, and in 1916 The Musical Times singled him out as "that excellent young 'cello player, Mr Giovanni Barbirolli." The principal of the Academy, Sir Alexander Mackenzie, had forbidden students to play the chamber music of Ravel, which he regarded as "a pernicious influence". Barbirolli was keenly interested in modern music, and he and three colleagues secretly rehearsed Ravel's String Quartet in the privacy of a men's lavatory in the Academy.From 1916 to 1918 Barbirolli was a freelance cellist in London. He recalled, "My first...
