What did Stravinsky once call Rachmaninoff?

Igor Stravinsky once referred to Sergei Rachmaninoff as "a great pianist and a great composer, but not a great man." This remark reflects Stravinsky's critical view of Rachmaninoff's artistic style, which he considered more traditional and less innovative compared to his own avant-garde approach. Despite this, Rachmaninoff's music has remained immensely popular and influential in the classical repertoire.
