Trudelies Leonhardt, the sister of the harpsichordist Gustav Leonhardt, is of Dutch-Austrian
parentage and comes from a family of musicians.
She studied with Johannes Röntgen, Anthon van der Horst and Nelly Wagenaar at the Amsterdam Conservatory where she was awarded the Soloist's Diploma with distinctions as well as the Elisabeth Everts prize. She also worked in Paris with Yves Nat and Marguerite Long.
Numerous orchestras have engaged Trudelies Leonhardt as soloist for their concerts, among which are the Amsterdam Concertgebouw Orchestra, the Tonhalle Orchestra of Zurich and the London Mozart Players.
She has long been interested in the Fortepianos of the late 18th and early 19th centuries and now entirely devotes her musical activities to their repertoire as a prolific recording artist.
