Eugenius Warming
Johannes Eugenius Blow Warming , known as Eugen Warming, was a Danish botanist and a main founding figure of the scientific discipline of ecology. Warming wrote the first textbook on plant ecology, taught the first university course in ecology and gave the concept its meaning and content. If one individual can be singled out to be honoured as the founder of ecology, Warming should gain precedence.
Warming was born on the small Wadden Sea island of Mand as the only child of Jens Warming , parish minister, and Anna Marie von Blow af Plskow . After the early death of his father, he moved with his mother to her brother in Vejle in eastern Jutland.
