The programme — facsimilé in pdf — of the Vienna Philharmonic's concert on 23 November 1941 announced this on page two: ‘Furtwängler's recovery’.
The article explains that this concert marks the return — at least to Vienna — of the eminent conductor after several months' downtime as a result of a serious skiing accident in Sankt-Anton in mid-February of the same year. On the slopes of this Tyrolean resort, the musician had a fall that led to several operations. Away from the conductor's podium, he seized the opportunity to write his long article, The Wagner Case, a critique of Nietsche's book.
On 19 October, Furtwängler resumed his activities, first in Berlin and Hamburg, then in Stockholm, Zurich and Bern.
The Berliner illustrierte Zeitung of 27 March had its cover with Furtwängler photographed shortly before his accident, but made no mention of it.
