Karl Haas (1900-1970) was a German-born conductor and music scholar who later worked in Britain. He founded the London Baroque Ensemble and became associated with early music performance.

In the Pristine catalogue he appears in concertos for two keyboards by J. S. Bach and C. P. E. Bach, with Lionel Salter, Charles Spinks and George Malcolm.

Haas’s significance lies in the mid-century revival of earlier repertory, where scholarship, performance and broadcasting often worked hand in hand.

His page is justified by repertory context and musical standing. Haas gives the Baroque shelf a thoughtful, historically minded frame.
