There is a long sequence of photographs in the Cavendish Laboratory showing the research students and staff every year from 1897; the 1902 photograph has J.J. Thomson in the middle, and includes Charles Francis Mott and Lilian Mary Reynolds, who were married in 1904 and whose son was Nevill Francis Mott. Charles was unlucky in his research project, which gave him no encouragement to continue, but he had a successful career, first as senior science master at Giggleswick, and then as Director of Education in the north–west of England, ultimately as Director for Liverpool. Miss Reynolds had been a star pupil of Cheltenham Ladie's College and at Cambridge was the best woman mathematician of her year, being classed equal with the eleventh wrangler. She was not at home in experimental physics—her heart was in applied mathematics—and after marriage, as her two children grew up, she devoted herself to social work. It is clear, from the loving memoir that her husband wrote and had published privately after her death, that she retained an active intelligence to the end.
