Schindler was born on 13 June 1795 in Medlov. He moved to Vienna in 1813 to study law, and from 1817 to 1822 was a clerk in a law office there. He was a competent, though not an exceptional violinist, and played in various musical ensembles, first meeting Beethoven in 1814. He gave up his law career, becoming in 1822 first violinist at the Theater in der Josefstadt, and from 1825 first violinist at the Theater am Kärntnertor. His acquaintance with Beethoven continued, and from 1822, he lived in the composer's house, as his unpaid secretary. Beethoven broke with Schindler in March 1825, and Karl Holz, a young violinist in the Schuppanzigh Quartet and friend of Beethoven, was engaged as the composer's secretary; though Schindler and Beethoven reconciled in August 1826, Holz continued as Beethoven's secretary with Schindler also tending to the composers' needs.After Beethoven's death in 1827, Schindler moved to Budapest where he worked as a music teacher, returning to Vienna in 1829. In 1831, he moved to Münster where he was a musical director; from 1835 he lived in Aachen, where he was municipal music director until 1840. In 1840, Schindler's biography of Beethoven was published in Münster. Later editions appeared in 1845, 1860 and 1871.In 1841–42 Schindler visited Paris, and met some of the famous musicians of the day.Schindler possessed a great part of Beethoven's estate, in particular around 400 conversation books that Beethoven used to converse with friends in his later years. Beethoven's estate, purchased by the Royal Prussian Library in Berlin in 1845, included 136 conversation books. Schindler retained the remainder, which were likely destroyed.Schindler died on 16 January 1864 in Bockenheim. Subsequent discredit and recent attempts at revival of credibility
