He studied medieval history and was a teacher of it at Rotterdam University of Applied Sciences.
Around 1978 he published Youthful Sinners in Constantinople by the journalist Esgo Taco Feenstra Kuiper(1857–1908), which, among other things, discussed the accessible ephebes in the place.
He debuted as a poet in 1981 with Ger Kleis at his publishing house Sub Signo Libelli with "Secretum secretorum" which also had the love for boys as the subject.
However, his 'life's work' seems to have been the biography of Jacques d'Adelswärd-Fersen (1880–1923), the first version of which he published in 1994 in the Amsterdam English-language magazine Paedika.
Adelswärd is known for his literary work, his interest in boys around the age of 15, and the scandal he caused in Paris in 1903.
