Peter Johannes Maria Masseurs (Halsteren, July 24, 1944 - Haarlem, January 5, 2019) was a Dutch trumpet player. At the age of 12 Masseurs started playing the trumpet, inspired by his father and a (childhood) friend who also played the trumpet. Masseurs studied trumpet at the Royal Flemish Conservatory in Antwerp, where he graduated with the Prix d'excellence. In 1963, Masseurs went to play in the Marine Band of the Royal Navy. In March 1970 he became principal trumpet player of the Rotterdam Philharmonic Orchestra. From 1982 until his retirement in 2009 he was one of the two solo trumpeters of the Royal Concertgebouw Orchestra (the other was Frits Damrow). He was also a principal teacher of trumpet at the Conservatory of Amsterdam. He played the concertos of Joseph Haydn, Henri Tomasi and Bernd Alois Zimmermann and the trumpet solo in Dmitri Shostakovich's Piano Concerto No. 1. In Sept. 2002 he gave the world premiere (also released on CD) of the concert for Flugelhorn by Willem Jeths. This assignment work for the RCO has been written especially for Masseurs. Besides Jeths, other composers also wrote for him, including Otto Ketting (Intrada written for Kettings own exam in 1958) and Martijn Padding (One Trumpet). Masseurs also recorded a CD of works for trumpet solo (in the series Soloists from the Royal Concertgebouw Orchestra).
