Conservation of cultural heritage as a distinct field of study initially developed in Germany, where in 1888 Friedrich Rathgen became the first chemist to be employed by a Museum, the Koniglichen Museen, Berlin (Royal Museums of Berlin). He not only developed a scientific approach to the care of objects in the collections, but disseminated this approach by publishing a Handbook of Conservation in 1898. The early development of conservation of cultural heritage in any area of the world is usually linked to the creation of positions for chemists within museums. In British archaeology, key research and technical experimentation in conservation was undertaken by women such as Ione Gedye both in the field and in archaeological collections, particularly those of the Institute of Archaeology, London.
