Carl Nägeli
Carl Wilhelm von Nägeli was a Swiss botanist. He studied cell division and pollination but became known as the man who discouraged Gregor Mendel from further work on genetics. He rejected natural selection as a mechanism of evolution, favouring orthogenesis, though the term was only coined in 1893, two years after his death, driven by a supposed "inner perfecting principle".
