When seen from an outsider's vantage point, the development of knowledge
in the sensory sciences must appear massive and the result of some
carefully followed master plan. In reality, it is the result of numerous
relatively independent human endeavors shaped by application of the
scientific method. The comprehensive construction of quantitative
theories of sense organ function has occurred only recently -but at an
explosive rate prefaced by centuries of expansion in the physical
sciences. Predicated on this growth, the twentieth century may become
known as the age of the biological sciences. With the exception of a
modest number of intellectual giants, there were few contributors to the
foundations of the sensory sciences before the dawn of this century. At
least 90% of existing knowledge has been produced by scientists working
in laboratories founded since 1920. If any single scientist and his
laboratory may be identified with the growth in the sensory sciences, it
is EDGAR DOUGLAS ADRIAN, First Baron of Cambridge and leader of the
Physiological Laboratory at Cambridge University, England. Lord ADRIAN'S
influence upon the sensory sciences was great, not only in terms of his
contribution to knowledge itself but also through the influence which he
exerted upon numerous young scientists who spent weeks or years at the
Cambridge laboratory and who later returned to their homelands and
colleagues with the seeds of vigorous research and quantitative inquiry
firmly implanted.
