Alexander, J. J. – The Devonshire Association (devonassoc.org.uk)
When he joined the Devonshire Association in 1909 as a life member Mr. Alexander at once made his mark as a historian, particularly of the Anglo-Saxon period, as it affected Wessex and Devon. Some sixty of his papers have appeared in the Transactions, and the last of this long series will be found in this volume. The papers and reports are noteworthy for straightforward English, logical argument, and the unmistakable pleasure he took when he could expose any fabulous belief, however popular. His mathematical training gave him great help in this. He was a most painstaking worker, of accurate scholarship and sound judgement.
