His first marriage, in 1775, was to Maria Anna Elisabeth Schindler, daughter of Philipp Ernst Schindler, a miniature painter and director of painting at the Viennese porcelain factory. Maria Anna died on 14 March 1779 of pneumonia. He married Aloysia Weber, a successful soprano, in Vienna on 31 October 1780. In that year he also agreed to support Aloysia's widowed mother Cäcilia with an annual payment of 700 florins. Mozart married Aloysia's younger sisterConstanze in Vienna in 1782, and thus became Lange's brother-in-law. The Mozarts and the Langes seem to have been friends, as the written record preserves various occasions that they socialized together, as did Wolfgang and Joseph individually. Both Lange and Mozart were Masons; see Mozart and Freemasonry. In 1783, Lange performed in one of Mozart's works, a "Masquerade" composed for Carnival. The characters were traditional figures of the Commedia dell'arte, and the music was composed by Mozart. Lange played Pierrot, and Mozart himself took the role of Harlequin. In 1786, Lange appeared in another work by Mozart, his opera Der Schauspieldirektor. He took the spoken role of Herz, his wife Aloysia taking one of the two primary soprano roles, Madame Herz. As of 1795, he lived separated from Aloysia. In 1808, he published his autobiography. From around 1800 on he lived together with a Therese Koch with whom he had three daughters.
Assessment
The tenor Michael Kelly, writing in his 1826 reminiscences, called Lange an "excellent comedian"; that is, player of comedy. Kelly had spent the early years of his career in Vienna as an opera singer.
Lange's portraits of Mozart and family
Lange painted his famous portrait of his brother-in-law in 1782/83. The following image is a detail of the portrait emphasizing Mozart's face: The complete painting is shown in the next figure. In March 2009 the musicologist Michael Lorenz was the first to realize that the painting originally was a miniature about 19 x 15 centimeters in size, showing only Mozart's face. It was later affixed to a larger canvas, apparently with the intention to portray Mozart seated at the piano, but the enlarged painting was never completed. Constanze Mozart, interviewed in old age by Vincent and Mary Novello, said that Lange's portrait was "by far the best likeness of him." Lange also painted a small portrait of Constanze in 1782 which was later enlarged: During Leopold Mozart's visit to Vienna in 1785, Lange drew a portrait of him as well, but this is lost. He continued to paint into his old age.
