[Chemistry research in Granada during the 20th century (1900-1975)].

We studied the development of chemistry research in Granada from 1900 to 1975. Initially we obtained quantitative data on publication output during three arbitrarily-defined subperiods (1900-1936, 1937-1955, and 1956-1975). The most important lines of chemistry research at university and national research council (CSIC) centers in Granada are described, and some considerations on the characteristics of these publications are provided. Scientific research slowly became consolidated during the 1930s. The Civil War led to substantial changes, and during the postwar years the influence of the CSIC led to the predominance of studies on silicates and clays (mineralogy, reactivity, applications) until well into the 1960s. After 1965 research lines became more diversified, with increasing numbers of studies in biochemistry, physiology and analytical chemistry.
