Eugen Sandow
Sandow's resemblance to the physiques found on classical Greek and Roman sculpture was no accident, as he measured the statues in museums and helped to develop "The Grecian Ideal" as a formula for the "perfect physique."  Sandow built his physique to the exact proportions of his Grecian Ideal, and is considered the 'father of modern bodybuilding, as one of the first athletes to intentionally develop his musculature to pre-determined dimensions.  In his books Strength and How to Obtain It  and Sandow's System of Physical Training, Sandow laid out specific prescriptions of weights and repetitions in order to achieve his ideal proportions.
