Sad news:

Professor Derek Pearsall, co-founder with the late Professor Elizabeth Salter of the Centre for Medieval Studies, University of York, passed away on Thursday 14 October, aged 90. He was an enormous influence on many of us who flourished under his tutelage and his scholarly reputation helped to establish York’s CMS as an outstanding beacon of teaching and research. May he rest in peace.

According to Wikipedia, Pearsall received an MA from the University of Birmingham in 1952, was Gurney Professor of English Literature at Harvard, and delivered the British Academy’s Israel Gollancz Memorial Lecture in 1998. I found his work very enlightening and enjoyed speaking with him at conferences. He will be missed.
