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 ..."
Edmund Beecher Wilson
Edmund Beecher Wilson (19 October 1856 – 3 March 1939) was a pioneering American zoologist and geneticist. He wrote one of the most famous textbooks in the history of modern biology, "The Cell". He and Nettie Maria Stevens were the first researchers to describe the chromosomal basis of sex, but they conducted their research independently of each other.
