Rembrandt Research Project
The Rembrandt Research Project (RRP) was an initiative of the Dutch Research Council (NWO). Its purpose was to organize and categorize research on Rembrandt van Rijn, with the aim of discovering new facts about this Dutch Golden Age painter and his studio. The project started in 1968 and consisted of the following team of art historians: Josua Bruyn, Bob Haak, Simon H. Levie, Pieter J. J. van Thiel, and Ernst van de Wetering. The older members of the team resigned in 1993 and the project was sponsored by NWO until 1998, but research continued until 2014 under the sole direction of Ernst van de Wetering. The RRP was considered the authority on Rembrandt's paintings and its opinion weighed heavily on whether a painting was to be considered genuine or not. The documentation generated by the project was transferred to the Netherlands Institute for Art History and renamed the Rembrandt Database.
