Vladimir Stasov
According to Jacob Weinberg (1879–1956), concert pianist, classical composer and close associate of Engel's, Engel had no interest in Jewish music until a catalyzing meeting in 1899 with Vladimir Stasov, art critic and a leading proponent of Russian nationalism in art and music. According to Weinberg, Stasov shouted at Engel, "Where is your national pride in your own people?" Engel experienced an epiphany, and took a profound interest in his Jewish musical roots.
