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 ..."
Imre Festetics
Many of the central principles the discipline of genetics were formulated by Imre Festetics through the study of sheep. Festetics formulated a number of rules of heredity and was the first to refer to these as "genetic laws of nature" ("Die genetischen Gesatze der Natur"). In so doing he used the term "genetic" for the first time, 80 years before William Bateson did so in his personal letter to Alan Sedgwick. Festetics created this new term to clearly distinguish his rules of heredity, or "genetic laws,"
from the "physiological laws" of Ehrenfels.In these ‘‘Genetic Laws,’’ Festetics was the first to recognize empirically the segregation of characters in the second
hybrid generation. He also linked heredity ("vererbung") with health and vigor
independently of external factors, stressing the role of inbreeding (combined with strong selection) in stabilizing character inheritance for preserving or developing new races. To illustrate the concept he used sheep and horse breeds as examples, although he also applied it to the human species by considering populations of isolated Hungarian villages, in which he had observed degenerative mental and physical characteristics. Festetics’s observations highlighted important correlations between variability, adaptation, and development. He also noted the consequences of selection and its role in heredity, believing that variability and his postulated laws of genetics were connected, acting together in breeding as well as in the natural processes controlling populations of different animals,including humans.
