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 ..."
Hologenome theory of evolution
In September 1994, Richard Jefferson first introduced the term hologenome at a presentation at Cold Spring Harbor Laboratory. At the CSH Symposium and earlier, the unsettling number and diversity of microbes that were being discovered through the powerful tool of PCR-amplification of 16S ribosomal RNA genes was exciting, but confusing interpretations in diverse studies. A number of speakers referred to microbial contributions to mammalian or plant DNA samples as 'contamination'. In his lecture, Jefferson argued that these were likely not contamination, but rather essential components of the samples that reflected the actual genetic composition of the organism being studied, and that the logic of the organism's performance and capabilities would be embedded only in the hologenome. Observations on the ubiquity of microbes in plant and soil samples as well as laboratory work on molecular genetics of vertebrate-associated microbial enzymes informed this assertion .
