Section A, Biographical, includes letters from the King George VI’s Private Secretary informing Thomson of the King’s wish to award him the Order of Merit. There are also press cuttings relating to Thomson and material concerning dinners and functions at Cambridge University.
Section B, Family and personal, chiefly consists of correspondence sent to Thomson’s wife, Rose, and to his brother Frederick. The former group of correspondence dates from 1882 to 1949 and comprises letters to Lady Thomson from various members of her family, including her twin sister, Violet, and letters of thanks for hospitality at Trinity College from visiting academics, scientists, politicians and others. The letters to Frederick Thomson are from Lady Thomson and date from 1906 to 1914. There are a few letters, 1903, from Thomson to his wife.
Section C, Correspondence, is presented in two sequences: general correspondence to Thomson dating from 1886 to 1939 and correspondence in French with foreign scientists 1898-1926. The general correspondence is from various scientists, politicians and academics, a large part of it being letters of thanks for hospitality at Trinity College. The correspondence in French, of both Thomson and his wife, is with a number of distinguished scientists, or their spouses, including Marie Curie, A.H. Becquerel and Paul Langevin.
Section D, Non-text material, has one item only: a film of Thomson delivering a lecture in 1934. There is also an index of correspondents.
