History and Etymology for progeria

Greek progḗrōs "prematurely old" (from pro- pro- entry 1 + -gērōs, adjective derivative from the stem of gḗras "old age") + -ia entry 1 — more at geriatric entry 2

Note: The term progeria was introduced by the British surgeon Hastings Gilford (1861-1941) in "Progeria: a form of senilism," The Practioner, vol. 73 (August, 1904), pp. 188-217. According to the author, "it was this peculiar mixture of relative bigness and littleness, youth and old age, which suggested the word micromegaly, at first used as a provisional name for the disease. But it is obvious that the most conspicuous feature is that of premature senile decay, and the name progeria, for which I am indebted to Mr. James Rhoades [1841-1923, Anglo-Irish poet and schoolmaster] and Professor Arthur Sidgwick [1840-1920, Oxford classicist], is not only a far better word, but it is a true description of the distinguishing features of the two cases" (p. 210).
