Henri Estienne ( , ; 1528 or 15311598), also known as Henricus Stephanus ( ), was a French printer and classical scholar. He was the eldest son of Robert Estienne. He was instructed in Latin, Greek, and Hebrew by his father and would eventually take over the Estienne printing firm which his father owned in 1559 when his father died. His most well-known work was the Thesaurus graecae linguae, which was printed in five volumes. The basis of Greek lexicology, no thesaurus would rival that of Estienne's for three hundred years. Among his many publications of Greek authors, his publications of Plato are the source of Stephanus pagination, which is still used to refer to Plato's works. Estienne died in Lyon in 1598. Life Henri Estienne was born in Paris in 1528 or 1531. His father instructed him in Latin, Greek, Hebrew, and typography, and according to a note in his edition of Aulus Gellius (1585), he picked up some Latin as a child, as that language was used as a in the multi-national household.
