Cor de Groot (July 7, 1914 – May 26, 1993) was a Dutch pianist and composer.
He was born in Amsterdam. He studied piano with Egbert Veen and Ulferts Schults, and composition and conducting under Sem Dresden. In 1932 he graduated with highest honours, playing a piano concerto written by himself. After becoming a soloist with the Concertgebouw Orchestra, he won the fifth prize at the 1936 international contest for pianists in Vienna. He played all over the world and recordings that exist demonstrate a strong sense of structure, a clean rhythmic attack and very precise dynamic shadings. He was a member of the Queen Elisabeth Music Competition's jury in 1956.
In 1959 a nervous disorder developed in his right hand but he continued playing repertoire for the left hand. He arranged more than 80 pieces for the left hand; his Apparitions, voor piano (linkerhand alleen) (1961) were described by one reviewer as "intense and expressive piano music that should make it a joy for a pianist to develop his left hand." Slowly he regained power over his right hand. He became musical director of the Dutch Broadcasting Foundation and promoted Dutch contemporary music. He made many recordings but also continued composing. His compositions include music for piano solo such as Variations imaginaires (1967); orchestral music; vocal work; and chamber music such as Sonatine pastorale for oboe and piano (1961). It has been stated that Dutch composer Gerard Schurmann composed his Bagatelles (1945) for de Groot, but this is not, in fact, the case. He died in Amsterdam in 1993.

Christian Ferras (17 June 1933 – 14 September 1982) was a French violinist.

Jean-Jacques (Jack) Sels (29 January 1922 – 21 March 1970) was a Belgian jazz saxophonist, arranger, and composer.

Herman Krebbers (18 June 1923 – Tilburg 2 May 2018) was a Dutch violinist.Born in Hengelo, Overijssel, Krebbers studied in Amsterdam with Oskar Back. He gave his first concert at age 10. In 1943, Krebbers debuted with the Royal Concertgebouw Orchestra. During the Second World War, he became a member of the Nederlandse Kultuurkamer, under the control of the Third Reich. This subsequently led to a 2-year ban on performances by him after the war.In 1950, Krebbers became co-concertmaster (leader) of the Residentie Orchestra, along with his childhood friend Theo Olof. Krebbers became concertmaster of the Concertgebouw Orchestra in 1962. In parallel, he had a career as a soloist and a chamber musician, and taught at the Amsterdam Muzieklyceum (now the Conservatorium van Amsterdam) for many years.
Krebbers suffered a shoulder injury from an accident on his boat in 1979, which forced him to resign from the Concertgebouw Orchestra in 1980. He then focused primarily on teaching, with his work at the Amsterdam Conservatory. His students included Frank Peter Zimmermann, Peter Tanfield, Jeanne Lamon, Vera Beths, Rudolf Koelman, Szymon Krzeszowiec, Jeroen de Groot, Emmy Verhey and André Rieu. He also served as chairman of the jury for the 1996 Leopold Mozart Violin Competition. He curtailed his teaching activities in 2001.
