Here’s an ad from the October 18 1926 edition of the Toronto Daily Star for both Heintzman pianos and an upcoming appearance by an opera singer.
Feodor Chaliapin (1873-1938) was a Russian basso who often worked with composer Sergei Rachmaninoff. His signature role was the title role in Boris Gudanov. While based in Russia, he maintained two separate families, one in Moscow and one in St. Petersburg.
As a result of the Russian revolution of 1917, he remained outside of his home country after 1921, eventually settling in Paris. His Wikipedia page states, “He was renowned for his larger-than-life carousing during this period, but he never sacrificed his dedication to his art.” Good for him!
He passed away in 1938, and was buried in Paris. In 1984, his body was transferred from Paris to Moscow in an elaborate ceremony. YouTube has some recordings of him, including this one from 1931.
