On the death of Lady Ramsay in 1937, Ramsay's daughter, Lady Tidy, asked Professor M W Travers to sort out the large collection of papers relating to her father which her mother had left. Travers added to these papers others which he had collected himself, and had them all bound up into 24 volumes, adding introductions and explanatory notes. The collection therefore contains correspondence and papers of Sir William Ramsay and of Morris W. Travers. The bound volumes contain letters to Ramsay, chronologically arranged by Travers, and copies of related printed papers. The remaining Ramsay papers are grouped according to their contents: laboratory notebooks, lecture notes, miscellaneous papers and published works. Professor Travers grouped Ramsay's published scientific papers into ten 'volumes'.
Travers's own papers are divided into two main sections: firstly papers relating to his work on Ramsay including various papers having some bearing on Ramsay's work. There is also material concerning his arrangement of the Ramsay papers. Secondly there are papers relating to Travers' own career, including papers on awards and distinctions; scrapbooks and miscellaneous material.
