French medieval history has dominated the professional life of Michael Jones from the moment he became a research student at Oxford. His published work, books and articles bear witness to an outstanding career. Whilst much of his work is concerned with France, he has also found time to devote to important projects in England, as author, editor, or both and, notably in retirement, the local history of the parish of which he is a resident. His editorial activity has also been greatly significant. From the early 1980s, he has been a lynchpin of a small team engaged in the research on the manor houses and smallest chateaux in Brittany. But that is not all, he has also contributed significantly to our other activities in France, including an important project on the townhouses of Cluny as well as the Le Yaudet project. In addition, he has participated annually and contributed to a private Franco-British seminar destined to explore the minor seigneurial domestic buildings of other French regions. These seminars have led to three published collective volumes. He has also been an enthusiastic participant in the annual Congres of the Soc. d'Histoire et d'Archeologie de Bretagne [SHAB], the longest-serving member of its Comite. The SHAB has published, not only many articles deriving from Michael's own work but also, almost annually, an article outlining our collective knowledge of a seigneurial building which we have presented to the Congres. The SHAB has also published several of Michael's monographs and provided encouragement and subventions for others. His total published output, both alone, and in collaboration with others, is remarkable.
