The January 12 1948 edition of the Toronto Daily Star contained two notices of upcoming events at the Eaton Auditorium and two at Massey Hall. I’ll do the Eaton Auditorium ones today and the others tomorrow.
Cellist Zara Nelsova was scheduled to appear on Wednesday of that week:
Zara Nelsova (1918-2002) was born in Winnipeg, and moved to London when she was a child. She appeared as a soloist with the London Symphony Orchestra when she was 13. During the war, she performed with the Toronto Symphony Orchestra. She moved back to London in 1949 and became an American citizen in 1955. During this time, she kept playing the cello, of course. She taught at the Juilliard School of Music in New York from 1962 until she passed away.
The edition also had an ad for the next performer who was to appear at the Eaton Auditorium:
Ricardo Odnoposoff (1914-2004) was born in Argentina. His family moved to Berlin, where he was a soloist with the Berlin Philharmonic Orchestra at the age of 17. He performed with the Vienna State Opera from 1933 to 1938, when he was forced to return to Argentina because he was not an Aryan. He moved to the United States in the early 1940s and became an American citizen in 1953; shortly after that, he returned to Vienna, where he taught from 1956 to 1993. Photographs of him apparently show him playing the violin quite joyfully; a Google search didn’t find any particularly joyful pictures of him, but I’m willing to believe it nonetheless.
