Born in Maribor, Schönherr studied in Graz under Roderich Mojsisovics von Mojsvar and was a composer of light orchestral music in Vienna.
These include the Annen-Polka, the Perpetuum mobile and Auf der Jagd by Johann, and the Delirien and Sphärenklänge waltzes by Josef.
Older records include a 78rpm recording (HMV C. 2905) from the late 1940s entitled Austrian Peasant Dances, which has Schönherr as the arranger: the conductor is Walter Goehr and the orchestra is listed generically as Symphony Orchestra.
A well-known 1963 LP from RCA Victor (Dynagroove LSC-2677) featuring Arthur Fiedler and the Boston Pops Orchestra entitled Concert in the Park, features a Wedding March not found on HMV C. 2905; whilst that recording contains two dances not recorded on the RCA LP.
The most extended recording was by Henry Krips and the Philharmonia Orchestra, recorded in 1958, comprising Hochzeitsmarsch aus Ebensee, Schuhplattler, Gugga Polka, Salzburger Schustertanz, Gstrampfter, Polsterltanz aus Ischl, Sautanz, and Bauerngalopp.
