Ulrich von Wilamowitz-Moellendorff (1848–1931) wrote surprisingly often to British colleagues. Usually it was a matter of a letter or two. The prolonged exchange with Gilbert Murray is the exception. More typical is the brief but important one with Sir James George Frazer. Extant evidence attests that he corresponded with some forty Englishmen and Scots. I omit Anglo-Irish: J.B. Bury, J.P. Mahaffy, L.C. Purser and the papyrologist, J.G. Smyly. The evidence is incomplete because most letters after the letter N were stolen and burned in the Berlin winter 1945–6. A first catalogue of his British correspondents is assembled. Because of the remoteness of much published biographical material, I include references to the important published sources and occasionally publish a document which otherwise would be forgotten. For the first time Wilamowitz's influence on the English scholars of his time is precisely documented.
