Hans Karl Albert Winkler (23 April 1877 in Oschatz – 22 November 1945 in Wachwitz [de], Dresden)[1] was a German botanist.
He is remembered for coining the term 'genome' in 1920,[2] by making a portmanteau of the words gene and chromosome.
[3] He wrote:[2]: 165 Ich schlage vor, für den haploiden Chromosomensatz, der im Verein mit dem zugehörigen Protoplasma die materielle Grundlage der systematischen Einheit darstellt den Ausdruck: das Genom zu verwenden ...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 ..."[4] Among his experiments was the discovery of chimeras (also chimaeras) by grafting a black Nightshade and tomato plant and observing a shoot which displayed characteristics of both plants.
Winkler also worked at the University of Naples, in Italy, where he researched the physiology of the alga Bryopsis.
[5] In 1903/04, he traveled around the world, visiting Ceylon, Java, Australia, New Zealand, Samoa and North America and later Borneo in 1924/25.
