Each New Year's Day since 1 January 1941, the VPO has sponsored the Vienna New Year's Concerts, dedicated to the music of the Strauss family composers, and particularly that of Johann Strauss II; the first such concert was given on 31 December 1939 by Clemens Krauss (see below, "#Period under National Socialism"), and led subsequent concerts on New Year's Day from 1941 until 1945. The postwar series of concerts was inaugurated in 1946 by Josef Krips. They were led by Krauss, then by concertmaster Willi Boskovsky from 1955 to 1979, and since 1980 have been led by a variety of leading conductors invited by the orchestra.
