The many friends and correspondents of the gifted author of the present volume will be grieved to hear that he died on 9th September 1906, having nearly completed his sixty-second year. Born at Lübeck in 1844, he afterwards studied law, theology, and literature at the Universities of Leipzig, Tubingen. Gottingen, and Basel, after which he resolved to devote himself entirely to literature and historical research. At a later period he settled in Edinburgh, assiduously carrying on his literary work and partly supporting himself by teaching. He also travelled a good deal in Scotland, England, and Ireland, winning the hearts of many friends by his gentle, amiable, and studious disposition, as well as by his outstanding musical talents. His historical researches also took him repeatedly to the Continent, and particularly to Northern Germany and to Sweden. To the latter country he was enabled to go, with the aid of a number of generous patrons and friends, in the autumn of 1905; and it is a pathetic and interesting fact that, at the age of sixty, he studied Swedish for the express purpose of making the needful historical researches for the present volume, and that he lived and travelled for several months in Sweden on the meagre pittance of about £60. His earlier historical works had earned him a high reputation for zeal and accuracy, but no pecuniary reward, in spite of which he entered enthusiastically upon his still more arduous task of breaking fresh ground in an entirely new field.
