Paul Steinitz (born Chichester, 25 August 1909; died Old Oxted, Surrey, 21 April 1988) was an English conductor and organist. He was one of the first musicians in the 20th century to make a careful study of the way that music by Johann Sebastian Bach should be performed so that it would sound like it used to in Bach’s day, in the early 18th century. He started a choir called the London Bach Society and a group of instrumentalists called the Steinitz Bach Players. He conducted them in lots of concerts. During the space of 25 years he performed all the cantatas of J.S. Bach in London. There are over 200 of them.
