In the north transept of Westminster Abbey is the grave of the celebrated physician Thomas Willis. The current stone was dedicated in 1961 to replace the original. The Latin inscription can be translated:
Mary, most beloved wife of Thomas Willis Doctor in Physick and daughter of Samuel Fell, D.D. and Dean of Christ Church in Oxford, valuable for piety, prudence and sweetness of manners, of all, but chiefly of her husband. She died loved and lamented on the vigil of All Saints 1670 and is buried here, expecting the eternal daybreak of that festival. In the same grave was buried their daughter Katherine, on the day after Michaelmas 1667. Here also lies the above mentioned Thomas Willis, most famous doctor of medicine, who died on the 11 November 1675 aged 54.
