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 ..."
J. B. S. Haldane
Haldane was the first to have thought of the genetic basis for the cloning of humans, and eventually super-talented individuals. For this he coined the term "clone", though the synonym "clon" (from the Greek word "klon" meaning "twig") had been used in horticulture since the 19th century. He introduced the term in his speech on "Biological Possibilities for the Human Species of the Next Ten Thousand Years" at the "Ciba Foundation Symposium on Man and his Future" in 1963.
