His dedication and contributions built the historic foundation for the black gospel music industry.
Many of today's major gospel artists started on Savoy under the leadership of Mendelsohn.
As a talent scout for the label, he discovered artists such as Nappy Brown,[1] C. J. Johnson, and James Cleveland, and promoted Cleveland with many background church choirs.
Mendelsohn was responsible for such historic acts as The Caravans featuring Albertina Walker, Inez Andrews, Shirley Caesar, Dorothy Norwood, Delores Washington, The Barrett Sisters, Dorothy Love Coates & The Gospel Harmonettes and Clara Ward.
As a songwriter, he co-wrote, with Rose Marie McCoy, Brown's 1955 hit single "Don't Be Angry".
