“Sir Ronald Fisher … could be regarded as Darwin’s greatest twentieth-century successor.”

Richard Dawkins River out of Eden (1995)


 “I occasionally meet geneticists who ask me whether it is true that the great geneticist R. A. Fisher was also an important statistician.”

 Leonard J. Savage Annals of Statistics (1976)


“[Kolmogorov] referred to The genetical theory of natural selection—‘das wundervolle Buch von R. A. Fisher.’ Two United States mathematicians sitting near to me were overheard to whisper ‘It can’t be the R. A. Fisher we know.’”
