Haeckel writes an unnamed colleague having just returned from two months in Sicily to acknowledge a letter he found waiting. Ernst Haeckel (1834-1919) was a renowned naturalist and professor of comparative anatomy who was responsible for identifying many species and who strove to bring Darwin's theories to a popular audience. At the end of his life, he is credited as being the first to coin the term "First World War."
