Jan Wijn was a Dutch pianist and piano teacher. He was born in Amsterdam on 19 May 1934, the son of drawing teacher Hendrik Meiert Ary Wijn and Margaretha Anna IJda Beemsterboer.
Wijn studied with Cornelius Berkhout at the Amsterdam Conservatory, receiving his soloist diploma in 1955. He subsequently studied with Béla Síki and Alicia de Larrocha. In 1960, he won first prize at the piano competition in the Spanish city of Ourense.
As a piano soloist, Wijn gave numerous recitals and orchestral concerts on tours that included England, France, Germany, Brazil, Romania, Spain and Russia. He regularly appeared as a soloist with symphony orchestras, including the Concertgebouw Orchestra.
His core repertoire included Debussy's Preludes, Liszt's Piano Sonata, Chopin's Piano Sonata in B minor, Op. 58, Ravel's Miroirs and Piano Concerto for the Left Hand, Manuel de Falla's Nights in the Gardens of Spain, and Richard Strauss's Burleske for Piano and Orchestra. He also performed piano concertos by Mozart, Beethoven, Rachmaninoff, Saint-Saëns and Ravel.
In 1976, symptoms of focal dystonia affecting the control of the fingers of his right hand forced Wijn to end his concert-pianist career. He thereafter concentrated on piano music for the left hand. From 1962 to 1968 he was a principal piano teacher at the Brabant Conservatory in Tilburg, and from 1968 until 2020 he taught at the Amsterdam Conservatory, where he trained many successful pupils. He was a sought-after competition juror and gave masterclasses in the Netherlands and abroad.
Wijn retired from the Amsterdam Conservatory in 2020 after 52 years there. A book about him was published to mark the occasion, and the television programme Podium Witteman devoted a special feature to him on 17 October 2020. On 31 October 2021, he received the City of Amsterdam's Frans Banninck Cocq Medal. He died in Soest on 12 July 2022, following a short illness, aged 88.
