Art historian and museum curator. Remmet van Luttervelt studied art history at Leiden University between 1936 and 1941. In 1943, he obtained his doctoral degree at Utrecht University under Professor Willem Vogelsang with a dissertation on country-houses along the Vecht River: De buitenplaatsen aan de Vecht. He published a rewritten version of this study in 1948. His career in the Dutch museum world began as early as 1941, with his appointment as research assistant at the Centraal Museum in Utrecht.

Rembrandt Research Project co-founder. Van Thiel attended high school in Bloemendaal at the Jac. P. Thijsse Montessori-Lyceum. He graduated in 1950. Between 1952 and 1961 he studied art history at Amsterdam University under I. Q van Regteren Altena. He in addition headed the Amsterdam Lichtbeelden Instituut (Slides Institute), and subsequently, from 1961 to 1963, the department of photo documentation of the Institute of Art history of Utrecht University, where he held a research position.

Coauthor of lexicon of artists, Geschiedenis der vaderlandse schilderkunst, sedert de helft der XVIII eeuw. Van der Willigen took the initiative to write the history of artists living in the Netherlands from the middle of the eighteenth century up to his time. In search for information on artists he published, in 1814, a request in the Algemeene konst- en letterbode. Among those who responded was Roeland van Eynden, who subsequently became the coauthor of the project.
