Brainin was made free after a few months, but Schidlof stayed in the camp, where he met Nissel. Finally Schidlof and Nissel were freed, and the three of them were able to study with violin teacher Max Rostal, who taught them free of charge. It was through Rostal that they met cellist Martin Lovett, and in 1947 they formed the Brainin Quartet, which was renamed the Amadeus Quartet in 1948.
