Ernst Mayr 1904-2005
"Mayr was one of the 20th century's leading evolutionary biologists. His work has contributed to the conceptual revolution that led to the synthesis of Mendelian genetics and Darwinian evolution, and to the development of the biological species concept. His theory of peripatric speciation has become widely accepted as one of the standard modes of speciation, and is the basis of the theory of punctuated equilibrium. Furthermore, his writings reflect, not only a technical expertise in biological subjects, but also a broad and penetrating understanding of the deeper philosophical issues involved."
