English: Grave in the Malvazinka Cemetery in Prague (section: FII, grave number 96; serial number on the official list: 138). Karel Urban (* 16 October 1870 - 30 January 1941) was an organ builder from Prague's Lesser Town, the author of many instruments in churches in Pilsen, Přerov, Prague, Sázava and other towns. Karel Urban was apprenticed in the Prague firm of organ builder Heinrich Schiffner. He worked throughout Bohemia, Moravia and Silesia from 1910 to the first half of the 20th century. He concentrated on the modification of older organs in the context of the period. Some of Karel Urban's works have also penetrated abroad. His son Josef Urban continued his father's tradition and, like Karel Urban, Josef also made pianos.
