Angelo Quaglio the Younger

Simon Quaglio (1795–1878) was a German stage designer.

He worked mainly in Munich, and was among the first designers to use built scenery instead of painted flats.

Simon's father, Giuseppe Quaglio (1747–1828), practiced scene painting in Mannheim, Frankfurt, and Ludwigsburg.

Simon's brother, Angelo Quaglio the Elder (1778—1815) was an architect and painter.

He designed and painted landscapes and architectural pictures for Sulpiz Boisserée's work on Cologne Cathedral.
