Founded by Thomas S. Kaplan and Daphne Recanati Kaplan, The Leiden Collection is among the largest and most important collections of seventeenth-century Dutch art in private hands. This unique “lending library” of paintings by Dutch Golden Age masters—including Rembrandt, Vermeer, Fabritius, and Van Mieris, among many others—has no permanent home and has been made readily available to the public through loans, and since 2017 through its website and extensive online catalogue.

Users of the online catalogue, which provides in-depth information about more than 175 paintings and drawings, are able to search The Leiden Collection by artist, date, medium and subject, learning about each individual work and pour over exquisite details by zooming in on high-resolution digital images. Scholarly essays illuminate important themes in the genre and provide in-depth analysis about the oeuvre of many artists who were connected to Rembrandt and his school, in particular. A wealth of videos explore different facets of the collection and provide trenchant insights into this important moment in art history.
