The introduction to the curve of human growth and development began in the Age of Enlightenment in eighteenth century in France. It was the friendship ofPhilibert Geuneau De Montbeillard and Compte de Buffon which grew stronger due to their common interests in the natural sciences. The desire to measure and describe the ,natural world as it,was and find the truth, made them empirically interested in the growth of De Montbeillard’s son and resulted in including this primary evidence of course of human growth. De Montbeillard ‘had been measuring his son every six months from his birth in 1759 until he was 18 years of age in 1777. This data was published by his friend Buffon in a supplement to Histoire Naturelle The boy’s measurements of height were reported in the French units of the time: pieds, pouces, and lignes (which correspond roughly to the present day units as a foot, inch and 12thpart of an inch). These units were translated by an American anatomist, Richard E. Scarnmon into centimetres and his results were published in the American Journal Of Physical Anthropology under the title ‘The First Seriatim Study of Human Growth’ in the year 1927. Subsequently, the measurement of body in childhood was published by Scammon in 1930 which provided a good starting point for the discussion 0 j’ growth curves of postnatal growth of the body. It became evident from this study that all children who live in normal environmental circumstances reflect patterns similar to the growth of De Montbeillard’s son. They may differ in absolute height or growth velocity, the pubertal growth spurt may be experienced earlier or later, but the shape of the curve is always the same. The description of distance and velocity curves has been given below.
