His comic talent was recognised, and Heinrich Schmelka recommended him to the management of the Königsstädtisches Theater in Berlin, where he was engaged from 1824.
Beckmann based him on "Woodcutter Nante", a small role in Karl von Holtei's play Ein Trauerspiel in Berlin, and it was similar to the Viennese comic character Staberl [de].
[3] His biographer in Biographisches Lexikon des Kaiserthums Oesterreich (1856) wrote: "Beckmann is a great researcher of human nature, he listens to people's drollest utterances, their comical nuances, their most humorous weaknesses and excesses, and gives them back again intact, unadulterated, with milder rather than more garish colours.... Beckmann is one of those artists of the Vienna Hofburgtheater who are always treated by the audience, in life and on the stage, with special benevolence and tremendous sympathy.
"[4] His biographer in Allgemeine Deutsche Biographie (1875) wrote: "Beckmann was of irresistibly comic vigour, and in particular he did this by means of a cosy, comfortable quality, which was peculiar to his performances, and by a wealth of droll ideas with which he loved to dress up his roles.
He was not exactly strong in character, but nevertheless his achievements pleased and were compellingly effective, because of the sunny cheerfulness that flowed from his whole personality.
