Several famous classical piano composers created monumental
keyboard works while managing severe physical and mental disabilities. Here is
a sampling
Maria Theresia von Paradis (1759–1824), an Austrian
pianist and composer, lost her sight before age five. She toured Europe as a
virtuoso, performed entirely from memory, and composed extensively for the
piano using special assistive composition boards.
Ludwig van Beethoven (1770–1827): fought progressive
hearing loss beginning in his late 20s, eventually becoming entirely deaf. He
continued composing masterworks like the Hammerklavier Sonata and late
bagatelles by feeling the vibrations of the instrument and relying on his inner
ear.
Robert Schumann (1810–1856) suffered from severe
mental illness, depressive episodes, and melancholia. He also experienced a
debilitating hand injury/dystonia that ended his concert pianist career,
shifting his immense creative focus entirely to composition (including his
celebrated Piano Concerto in A minor).
Alexander Scriabin (1872–1915) and Sergei
Rachmaninoff (1873–1943): both experienced severe physical ailments and
chronic nerve/joint pain affecting their hands and bodies during various points
of their intensive performing and composing careers
Maurice Ravel (1875–1937) endured a progressive
neurological brain disease in his later years. Though it limited his output,
his earlier keyboard innovations and pieces remain foundational. (He also
famously wrote the Piano Concerto for the Left Hand for Paul
Wittgenstein, a pianist who lost his right arm in WWI).
