Biographical history

Peter Clement Bartrum (1907-2008) was born in Hampstead, London, educated at Queen's College, Oxford, and worked as a meteorologist in the Colonial Service, 1932-1955. He spent much of his life researching the mediaeval Welsh genealogical manuscripts, learning to read Welsh to do so, and coming to be considered an authority on them. He also had an interest in the early Arthurian legends. He published 'Welsh genealogies AD 300-1400' (8 vols, 1974), 'Welsh genealogies AD 1400-1500' (18 vols, 1983), 'Early Welsh genealogical texts' (1986), and 'A Welsh classical dictionary : people in history and legend up to about AD 1000' (1993). These are in the process (2015) of being made available online at Obituaries were published in the Times, 21 Aug., Guardian and Independent newspapers, both 20 Sept. 2008, and Studia Celtica 43 (2009), pp. 221-222.

Notes area


Dr Bartrum's work is undated. Much of the work is on the backs of [meteorological?] computer print-outs, ephemeral Berkhamsted notices and other re-used papers. The Harleian MS 6068 file includes two coded pages from war-time message pads, while the Peniarth MS 132 files, at least, are in part on the backs of notes towards Bartrum's published 'Early Welsh genealogical texts' (1986). The dates given here are no more than the occasional dates found overleaf and on the occasional enclosed letter, and should be given very little weight.
