D'ARCY WENTWORTH THOMPSON

Sir 'D'Arcy Wentworth Thompson' (May 2, 1860–June 21, 1948) was a biologist, mathematician, classics scholar and the author of the 1917 book, ''On Growth and Form'', an influential work of striking originality. Nobel laureate Peter Medawar called ''On Growth and Form'' "the finest work of literature in all the annals of science that have been recorded in the English tongue".^[1] Born in Edinburgh, Scotland, Thompson has been called "the first biomathematician" by Simon Singh^[2]. He died in St. Andrews, Scotland.
Thomson was appointed Professor of Biology in Dundee (1884), Professor of Natural History at St Andrews (1917) -- a post he held for a record 64 years. Elected a Fellow of the Royal Society in 1916, he was awarded the Darwin Medal in 1946, and was knighted in 1937. He was also an outstanding Greek scholar.

''On Growth and Form''

The central thesis of ''On Growth and Form'' is that biologists of his day overemphasized the role of evolution, and underemphasized the roles of physical laws 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 sequence has become a textbook staple.
Utterly ''sui generis,'' the book never quite fits into the mainstream of biological thought. It does not really present any single unifying thesis, 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.
