It seems Hasan Niyazi, the tireless blogger, talented amateur art historian, and independent Renaissance scholar behind the popular art history blog Three Pipe Problem and the ambitious Open Raphael project, has died suddenly at 37, the same tender age as his idol, Raphael.
I first interacted with Hasan in 2010, and we discussed things by email now and again over the years. A man of science by training, he harbored endless enthusiasm for evidence-based scholarship in art history, for the importance of the Digital Humanities movement, and for free and open educational content– values we shared.
If you're so inclined, take a moment to look at his websites, which now stand as monuments to his energy, focus, idealism, passion for beauty, and love of learning.
Edit: See also the moving tributes by Prof. Ben Harvey, Prof. Monica Bowen, and Dr. Francis DeStefano. Above all, Hasan promoted community, encouraged cooperation, and took delight in sharing the discoveries and insights of one and all. In some measure, the art historical blogosphere itself is his handiwork.
