Born in Amsterdam in 1952, Marinus studied trumpet and timpani at the Conservatory of Amsterdam with his grandfather, Marinus Komst (Solo Trumpet, Royal Concertgebouw Orchestra) and timpani with Jan Labordus (Solo Timpani, Royal Concertgebouw Orchestra).

In 1971, he started his timpani career in the orchestra of Friesland (north of Holland) and in 1991, became Solo Timpanist of the Royal Concertgebouw Orchestra.

Marinus has a great collection of 70 vintage timps and plays Adams drums (calfo) and original Schnellar pedal drums (1910). His hobbies are fishing and restoring old timpani.
