Wilhelm Johannsen

Wilhelm Johannsen (3 February 1857 – 11 November 1927) invented the term "gene". He was a Danish pharmacist, botanist, plant physiologist, and geneticist. 

He is best known for coining the terms gene, phenotype and genotype, and for his 1903 "pure line" experiments in genetics.Roll-Hansen, Nils 1979. The genotype theory of Wilhelm Johannsen and its relation to plant breeding and the study of evolution. Centaurus 22.
