Murray Perahia :
The following is copied from Wikopedia :
In 1990, Perahia suffered a cut to his right thumb, which became septic. He took antibiotics for this condition, but they affected his health. In 1992, his career was threatened by a bone abnormality in his hand causing inflammation requiring several years away from the keyboard, and a series of operations. During that time, he says, he found solace through studying the music of Johann Sebastian Bach. After recovering, he produced a series of award-winning recordings of Bach's keyboard works in the late 1990s, most notably a cornerstone rendition of the Goldberg Variations.
In early 2005, Perahia's hand problem recurred, prompting him to withdraw from the concert stage on the advice of his doctors. He cancelled several appearances at Barbican Centre, as well as a 10-city national tour of the United States, but returned in fine form with recitals in German cities in 2006 and at the Barbican in April 2007.
In autumn of 2007, he completed a triumphant 10-city tour of the United States and conducted master classes in Salt Lake City, Utah. Owing to his hand problem, and on the advice of his doctor, Perahia cancelled a February 2008 solo recital at Barbican Centre and a tour in the United States with the Academy of St. Martin in the Fields (March and April 2008). He returned to the platform in August 2008, touring with the Royal Concertgebouw Orchestra under the direction of Bernard Haitink, and had an Asian recital tour in October and November.
Just to add a personal touch to this : I was at Perahia's "historic" return to Carnegie Hall in the early 1990's: a most memorable moment.
