182 Johann Joseph Fux, b. 1660, d. 1741; Kapellmeister at Vienna; published his _Gradus ad Parnassum_ at Vienna in 1725. 183 See supra, p. 74. 184 * I speak here only of those pupils who made music their profession. But, besides these, Bach had a great many other pupils. Every dilettante in the neighbourhood desired to boast of the instruction of so great and celebrated a man. Many gave themselves out to have been his pupils who had never been taught by him. 185 See Spitta, i. 522; Schweitzer, i. 214 for farther details regarding Vogler, who died circ. 1765. 186 Gottfried August Homilius, b. 1714, d. 1785; pupil of Bach, circ. 1735. Cantor of the Kreuzschule, Dresden. 187 Christoph Transchel (1721-1800) taught music at Leipzig and Dresden; Bach’s pupil and friend, circ. 1742. See Spitta, iii. 245. 188 Johann Gottlieb (or Theophilus) Goldberg, clavicenist to Count Kaiserling (infra, p. 119) for whom Bach wrote the so-called _Goldberg Variations._ He was born circ. 1720 and was a pupil of Bach from 1733-46. 189 Johann Ludwig Krebs, b. 1713, d. 1780; Bach’s pupil, 1726-35. Bach said of him that he was “the best crab (Krebs) in the brook (Bach).” 190 Johann Christoph Altnikol, d. 1759. 191 Johann Friedrich Agricola, b. 1720, d. 1774; pupil of Bach circ. 1738-41; Director of the Royal Chapel, Berlin. 192 Pier Francesco Tosi, b. circ. 1650; singing master in London. His _Opinioni de’ canton antichi e moderni, o sieno osservazioni sopra il canto figurato_ was published at Bologna in 1723. 193 Johann Gottfried Müthel, b. circ. 1720, d. circ. 1790; pupil of Bach in 1750 and resident in his house at the time of his death; organist of the Lutheran Church, Riga. 194 Johann Philipp Kirnberger, b. 1721, d. 1783; Bach’s pupil, 1739-41. 195 Louisa Amalia, of Brunswick-Wolfenbüttel, wife of Frederick the Great’s brother, and mother of his successor, Frederick William II. (1786-97). 196 The second work was published in 1773 at Berlin. For the first, see supra, p. 74. 197 Johann Christian Kittel, b. 1732, d. 1809; one of Bach’s latest pupils; Organist of the Predigerkirche, Erfurt. He is said to have possessed a portrait of his master and to have rewarded his pupils for good playing by drawing the curtain which usually covered the picture and permitting them to look upon it. It is, perhaps, the portrait, recently discovered by Dr. Fritz Volbach, which is reproduced at p. 92 of this volume. 198 Nothing seems to be known of him. 199 Johann Martin Schubart succeeded Bach at Weimar in 1717. He was born in 1690 and died in 1721. See Spitta, i. 343.
