Karen Kain, arguably Canada’s most beloved dancer, will be appointed artistic director of the National Ballet of Canada. “Ms. Kain, 54, succeeds James Kudelka, whose surprise resignation from the post last month takes effect June 30. Mr. Kudelka has said he wants to spend more time creating ballets and less time dealing with the administrative headaches often associated with the job. For seven years, Ms. Kain has been the company’s artistic associate under Mr. Kudelka.”
