Quotes | On

The following are quotes:

Rumford has informed us himself that he should probably have remained in the modest condition of his ancestors if the little fortune which they had to leave him had not been lost during his infancy. Thus, like many other men of genius, a misfortune in early life was the cause of his subsequent reputation. His father died young [age 2]. A second husband removed him from the care of his mother, and his grandfather, from whom he had everything to expect, had given all he possessed to a younger son, leaving his grandson almost penniless. Nothing could be more likely than such a destitute condition to induce a premature display of talent.”
Georges Cuvier (c.1815), Publication [1]
