2 IN MEMORIAM JACOB BAREND (JAAP) VAN BENTHEM (23 December 1937 – 9 January 2023)* On 9 January 2023, Jaap van Benthem died at the age of 85. He was known internationally as a specialist on f ifteenth- and early-sixteenth-century music. Closer to home, many also knew him as an inspired music theory teacher and advocate of nineteenth- and twentieth-century Dutch music. Jaap was born in Rotterdam. Being the eldest child in a teaching family, it was a matter of course that Jaap would also be trained as a secondary school teacher (1956-60). By the age of twelve he had taken up the study of piano at the conservatory of Rotterdam. After completing his piano studies under Jaap Callenbach in 1959 and obtaining his teaching qualif ication one year later, Jaap opted for a career in music and began studying music theory with Herman Strategier and Ton de Leeuw at the conservatory of Utrecht (1962-65). His employment in music started with teaching positions in music theory at the conservatories of Utrecht (1963-66), Rotterdam (1965-74) and Amsterdam (1972-74). By the time he had begun to teach music theory at the institute of musicol- ogy at Utrecht University (in 1972), Jaap had already become fascinated by Josquin. He was primarily interested in the relationship between texts and music, a fascination he shared with his wife, the soprano Loes de Koning. This specif ic interest resulted not only in articles and editions but also in the composition of several Lieder. As a musicologist, Jaap was self-taught, although he picked up many skills of the profession from Willem Elders with whom he worked for a long period. Jaap became a vital contributor to the Tijdschrift van de Vereniging voor Nederlandse Muziekgeschiedenis, publishing a series of articles between 1970 and 1989 on topics such as authenticity in Josquin chansons, the transmission of fifteenth-century music, and musica f icta. 1 * I would like to thank Fabrice Fitch and Willem Elders for the improvements they have suggested and Loes de Koning for checking the factual content of the text. 1 An almost complete survey of Van Benthem’s scholarly work may be found in Eric Jas, ‘Jacob Barend (Jaap) van Benthem (23-12-1937): List of publications’, TVNM 67 (2017), 5-9.
