Hans Winkler
Hans Karl Albert Winkler (23 April 1877 – 22 November 1945) was a German botanist. He was Professor of Botany at the University of Hamburg, and a director of that university's Institute of Botany. Winkler coined the term 'heteroploidy' in 1916. He is remembered for coining the term 'genome' in 1920, by making a portmanteau of the words gene and chromosome. He wrote: 
This may be translated as: "I propose the expression "Genom" for the haploid chromosome set, which, together with the pertinent protoplasm, specifies the material foundations of the species ..."
Richard Dawkins
Although Dawkins invented the term "meme", he has not claimed that the idea was entirely novel, and there have been other expressions for similar ideas in the past. For instance, John Laurent has suggested that the term may have derived from the work of the little-known German biologist Richard Semon. Semon regarded "mneme" as the collective set of neural memory traces (conscious or subconscious) that were inherited, although such view would be considered as Lamarckian by modern biologists. Laurent also found the use of the term "mneme" in Maurice Maeterlinck's "The Life of the White Ant" (1926), and Maeterlinck himself stated that he obtained the phrase from Semon's work. In his own work, Maeterlinck tried to explain memory in termites and ants by claiming that neural memory traces were added "upon the individual mneme". Nonetheless, James Gleick describes Dawkins's concept of the meme as "his most famous memorable invention, far more influential than his selfish genes or his later proselytising against religiosity".
