One of my favorites was Ruth Slenczynska. She is remarkable playing Chopin.
At an early age she won many competitions and toured the US. Her first LP was recorded sometime in the 60s. Not sure exactly. She became an Artist in Residence at Souther Illinois University, School of Music, Edwardsville, Illinois. There she taught piano to high level aspiring pianists from around the country at SIU. I was a music major at the time and attended a number of her recitals and concerts. I believe I still have her first 2 LPs.
There is a recent Youtube video of one of her performances in Japan. A very small woman with a great smile and a real passion for music, especially Chopin.
