Assessment of the physical dimensions of the human body and application
of this knowledge to the design of tools, equip- ment, and work are
certainly among the oldest arts and sciences. It would be an easy task
if all anthropometric dimensions, of all people, would follow a general
rule. Thus, philosophers and artists embedded their ideas about the most
aesthetic proportions into ideal schemes of perfect proportions. "Golden
sections" were developed in ancient India, China, Egypt, and Greece, and
more recently by Leonardo DaVinci, or Albrecht Durer. However, such
canons are fictive since actual human dimensions and proportions vary
greatly among individuals. The different physical appearances often have
been associated with mental, physiological and behavioral
characteristics of the individuals. Hypocrates (about 460-377 BC) taught
that there are four temperaments (actually, body fluids) represented by
four body types. The psychiatrist Ernst Kretchmer (1888-1964) proposed
that three typical somatotypes (pyknic, athletic, aesthenic) could
reflect human character traits. Since the 1940's, W. H. Sheldon and his
coworkers devised a system of three body physiques (endo-, meso-,
ectomorphic). The classification was originally qualitative, and only
recently has been developed to include actual measurements.
