Geneticists Johannsen and Bateson, sitting in a garden. Danish geneticist Wilhelm Johannsen (left, 1857-1927) was professor of botany and plant physiology and vice-chancellor (from 1917) at what would be the University of Copenhagen. He coined the terms 'gene', 'phenotype' and 'genotype'. British geneticist William Bateson (right, 1861-1926) proposed that evolution occurred by a series of 'jumps' (discontinuity) rather than the continuous change of natural selection. He coined the word 'genetics'. He lived in Merton Park, Surrey, from 1910, where he was director of the John Innes Horticultural Institution. Photographed in around 1925.
