This article profiles Francis Galton, an explorer, geographer, anthropologist and biologist, biometrecian and meteorologist and originator of Eugenios. It must surely have been a great satisfaction to Sir Francis Galton to witness the development of the fundamental ideas which he contributed to the study of heredity. It may be useful to recall very briefly the three greatest of these. Galton long ago expressed, what has since been so well substantiated, the idea of the germinal continuity of generations, the main clue to understanding why like tends to beget like. Galton was also one of the prompters of the extremely useful modern scepticism as to the transmission of somatic modifications. In 1873 Galton expressed the firm conviction that acquired modifications are barely, if at all, inherited in the correct sense of that word. Even greater, perhaps, was the service Galton did in showing that exact quantitative methods can be applied to the study of inheritance. In his "Law of Regression" he showed that if one takes, in a stable population, mating at random, a group of all the parents with the same amount of a character, say stature, then the average of the same character in their offspring will be nearer to the mean of the whole population than the parental value was.
