[5] In a Conversation Book from the year 1825, Holz writes that till then “Christus am Ölberg” had always drawn full houses, but that the court official in charge of musical affairs (~Hofmusikgraf~) had not allowed further performances to be given. [6] Anton Kraft was 14-1/2 years old at the time. [7] The following observation on the sonata by Czerny is also interesting: “In the Sonata written for Bridgetower and dedicated to Kreutzer, Op. 47 (of which the first movement was composed in four days and the other two [?] added from a sonata already completed), the concluding passage [Illustration] is said to be borrowed from a piece of Kreutzer’s already in print. I had this assurance immediately after the publication of the Beethoven Sonata from a French musician (1805). It would be worth while to investigate the matter. Perhaps therein lies the reason of its dedication.” And further: “Bridgetower was a mulatto and played very extravagantly; when he played the sonata with Beethoven it was laughed at.” [8] Letters and other documents, some of which were placed in Mr. Thayer’s hands by Samuel Appleby, Esq., relative to Bridgetower, are printed in an appendix to Vol. II of the first German edition of this biography and as foot-notes and otherwise in Vol. III. What is essential in the memoranda and documents can be put into a much smaller compass. The subscription for the concert amounted to 1140 florins and the list was headed by the English envoy. Bridgetower’s father was known in England as the “Abyssinian Prince,” and Mr. Thayer speculates whether the title was genuine or but a sobriquet given to him suggested by Dr. Johnson’s “Rasselas”; but it will appear presently that he was called an “African Prince,” not an Abyssinian; how his father got to Biala in Poland, where Bridgetower was born, or whether his mother was a German or a Pole, remains a mystery which has not yet been cleared up. The first memorandum of information in Mr. Thayer’s collection was in the shape of an excerpt from a communication from London written by Abt Vogler and printed in Bossler’s “Musikalische Correspondenz” on July 7, 1790. Abt Vogler’s letter bears date London, June 6, 1790; in it he said: “Last Wednesday, June 2nd, I attended a concert here in Hanover Square where two young heroes contested with each other on the violin and all music-lovers and cognoscenti found most agreeable entertainment for three hours. The two played concertos alternately and both won the warmest applause. The quartet, however, which was played by young virtuosi whose combined ages did not reach 40 years, by virtue of a fine, cheerful, witty and yet harmonious performance exceeded all the expectations that experienced players could gratify. The first violin was played by Clement of Vienna, eight and one-half, the second by Bridgetower of Africa, ten years of age.”
