This year (1989) marks the 100th anniversary of the Kansas Geological Survey's location at the University of Kansas. Perhaps no single name is as closely associated with the Survey as Raymond Cecil Moore, director of the Survey and state geologist of Kansas from 1916 to 1954 (Figure 1). Moore was, without doubt, the principal influence on the Survey's character and direction in the first half of the twentieth century, and he continued to be involved in the Survey and its research until his death in 1974. In spite of Moore's seminal influence at the Kansas Geological Survey and the University of Kansas, a formal memorial for Moore was never published and a bibliography of Moore's written works never compiled. Thus, the following memorial and bibliography are published to commemorate Moore, 100 years after the founding of the organization that he affected most significantly and to which he devoted so much of his time and talent, the Kansas Geological Survey.
