Isabelle Vengerova (1 March [O.S. 17 February] 1877 – 7 February 1956) was a Russian, later American, pianist and music teacher
She was born Izabella Afanasyevna Vengerova (Изабелла Афанасьевна Венгерова), in Minsk (now in Belarus). Her elder brother Semyon Vengerov was a venerable literary historian. She studied the piano at the Vienna Conservatory with Josef Dachs, and privately with Theodor Leschetizky; in Saint Petersburg she studied with Anna Yesipova. From 1906 to 1920 she taught at the Imperial Conservatory in St Petersburg and then toured the USSR and Western Europe from 1920 to 1923, when she settled in the USA.
In 1924 she helped found the Curtis Institute and in 1933 joined the faculty of the Mannes College, teaching at both institutions until her death in New York in 1956. Vengerova was also known for her painstaking attention to detail and for a psychological insight that brought out the best in each pupil. While she denied having a particular method, she drilled all students in techniques designed to achieve expressive playing and beautiful tone, keeping the fingers close to the keys for evenness and a seamless legato;
