OBITUARY NOTICES 211 Percy George Thompson To those of the writer's generation, it is difficult to think of the Essex Field Club without thinking simultaneously of Percy Thompson, who was its enthusiastic Secretary for over 30 years until he resigned in 1948, and, during the greater part of this period, Editor of the Essex Naturalist and the Curator of the Essex Museum. He was always reticent about his private life, and although his daughter (Mrs. Newbury) has supplied me with some biographical notes, I think it would have been Thompson's wish that only the barest minimum should be made public. He was born at Rotherhithe in 1866, the youngest child of a large family. He entered an architect's office as a boy, and with characteristic energy and determination, he rose, in spite of adversity, to become an architect. He pursued this profession until he was about 60 years old. In his latter years he devoted most of his time to the work of the Essex Field Club and its Museum, and he was, I believe, happiest when thus engaged. He married Annie Scourfield, a first cousin of D. J. Scourfield, in 1887, and their married life extended over 64 years. They had two children. Mrs. Thompson, who was also an enthusiastic member of the Essex Field (Tub, was a great help to her husband in his work for the Club, and it was seldom that she did not accompany him to its meetings. I first met Thompson in 1923 when I became assistant curator at the Essex Museum, and it was my privilege to serve under him for over four happy years. It was then that I discovered that his somewhat austere manner and occasional petulant little outbursts were the thinnest of veneers covering a genial and kindly character. Later, when I became more in- timately associated with him in Essex Field Club affairs, I found no reason to modify my first assessment of him. He was the most helpful and loyal of colleagues, and did much to make my occupation of the Presidential Chair an easy and pleasant one. It was about the time that I first knew him, I believe, that Thompson's main interest was veering from natural history to archeology and antiquities. That must not be taken to mean that he was not still an enthusiastic naturalist. His range of knowledge was enormous, his interests catholic, and he must have had a prodigious memory. I have seen him name molluscan shells, or British beetles, accurately to a species, and from memory, after making his characteristically naive statement—"Well, I haven't touched the molluscs (or beetles) for over 40 years, but I'll see what I can do": and what he could do was to point out, with perfect lucidity, the minutae on which the specific determination depended. He had a good knowledge of the British lichens, on which he had worked with Robert Paulson, while he knew the British mosses well. Of birds, not a few insects, and flowering plants, he had more than an average knowledge. Whatever he studied, he did so with zeal. As a young man, he had worked on the rotifers, and with characteristic thoroughness had learnt German because he found that most of the literature he required was written in that language. His knowledge of Essex prehistory was wide, and I believe he was expert on archaeological matters, and especially those connected with the county. He maintained a life-long interest in geology, and his daughter tells me that one of her earliest recollections of her father was his classes in geology and similar subjects, held in his house and well attended, especially by local school teachers.
