German architect, a pupil of Karl von Fischer (1782-1820). He completed Fischer's Hoftheater, Munich (from 1820), Quaglio's charming Gothic Hohenschwangau, near Füssen, Bavaria (1839-50), and the Mariahilfkirche, Au, Munich (from 1839), all in Bavaria, but his chief importance lies in his contribution to the Rundbogenstil, notably his splendid brick and terracotta (with stone dressings) fusion of Early Christian and Byzantine architecture at the St. Boniface basilica, Munich, which drew on exemplars in Ravenna and Rome (e.g. San Paolo fuori le Mura). He also designed the Corinthian exhibition building opposite von Klenze's more lively Glyptothek (Sculpture Gallery) in the Königsplatz, Munich (1816-31). //
