His work included commissions from the Prague Mint and Paris Mint. From 1924 to 1926 he was editor of the "Dílo" art magazine. He had a long-running project (1929 to 1939) on a hill of Křemešník where he intended to establish a coin museum in an old windmill, greatly extended to accommodate the proposal. The project was designed by his architect friend Kamil Hilbert. He died in Prague on 9 February 1941. Much of his medal work is highly collectible. Originally buried in Prague he was reinterred in the cemetery at Pelhřimov in the 21st century to be close to his home town. There is  a museum in that town to his memory. Works
