Friedrich Schlichtegroll

Schlichtegroll's biography competed with another early work by Franz Niemetschek, which relied on the testimony of Mozart's widow Constanze. The Schlichtegroll biography is relatively harsh on the role Constanze played in Mozart's life, as might be expected given Nannerl's antipathy to Constanze; for details see Maria Anna Mozart. According to the Grove Dictionary of Music, "Constanze bought up and destroyed the entire edition of the Nekrolog (the publication containing Schlichtegroll's obituary), apparently disliking its portrayal of her."

Some modern scholars take a dim view of Schlichtegroll's work. Cliff Eisen and Simon P. Keefe vividly depict him as the first in a long and dubious tradition: the tradition of depicting Mozart as a strange mixture of angel and beast, Tamino and Papageno: sublime where his music was concerned, but pathetically inadequate in worldly matters. Bruce Cooper Clarke, who has compiled an extensive web-posted commentary on Schlichtegroll's work, assesses him thus: The debt posterity owes to Friedrich Schlichtegroll is mixed. On the one hand, because he asked questions not long after Mozart had died and offered the prospect of publication, Mozart's sister and others who were acquainted with the composer were led to put something of their remembrances in writing, reminiscences that otherwise might never have been recorded. On the other hand, through his handling of these materials, Schlichtegroll gave a powerful start to the formation of an "eternal-child" myth that, despite its irrelevance and wrongheadedness, has intruded ever since on every effort of Mozart biography to see its subject whole.

His recorded language was German. He was the child of Daniel Schlichtegroll. 2 children are recorded: Antonin von Schlichtegroll and Nathanael Schlichtegroll.

Friedrich Schlichtegroll is recorded as musicologist, music historian, writer, journalist and biographer.
