D'Arcy Wentworth Thompson (May 2, 1860- June 21, 1948) was a biologist and mathematician and the author of the 1917 book, On Growth and Form, an influential work of striking originality. Born in Edinburgh, Scotland, he has been called "the first biomathematician." He died in St. Andrews, Scotland.
The central thesis of On Growth and Form is that biologists of his day overemphasized the role of evolution, and underemphasized the roles of physics and mechanics, as determinants of the form and structure of living organisms.
Thompson pointed out example after example of correlations between biological forms and mechanical phenomena. He showed the similarity in the forms of jellyfish and the forms of drops of liquid falling into viscous fluid, and between the internal supporting structures in the hollow bones of birds and well-known engineering truss designs. His observations of phyllotaxis (numerical relationships between spiral structures in plants) and the Fibonacci series has become a textbook staple.

Utterly sui generis, the book never quite fit into the mainstream of biological thought. It does not really present any single central discovery, nor, in many cases, does it attempt to establish a causal relationship between the forms emerging from physics with the comparable forms seen in biology. It is a work in the "descriptive" tradition; Thompson did not articulate his insights in the form of experimental hypotheses that can be tested. Thompson was aware of this, saying that "This book of mine has little need of preface, for indeed it is 'all preface' from beginning to end."
The huge (1116 pages in an edition currently in print), well-written, and extensively illustrated tome has enchanted and stimulated generations of biologists, architects, artists, and mathematicians, and, of course, those working on the boundaries of disciplines.
Perhaps the most famous part of the work is Chapter XVII, "The Comparison of Related Forms." He explored the degree to which differences in the forms of related animals could be described by means of relatively simple mathematical transformations.
