Fritz (1872-1952) was entrusted with the technical management, Reinhold (1874-1955) with the commercial administration and Julius (1877-1970) with the musical consulting and artist promotion.
Wolf Dieter Neupert (*1937), grandson of Fritz N., took over sole responsibility for the company in the fourth generation.
The "Neupert Piano Historical Collection", which was continued by his descendants and today comprises over 300 exhibits, has been housed in the Germanisches Nationalmuseum in Nuremberg since 1968.
On the basis of this collection, Neupert built harpsichords, then also spinets, clavichords and fortepianos from 1906 onwards.
This made the company the largest of its kind in Germany and the world's oldest among the workshops engaged in harpsichord building today.
