Henri Estienne, 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.

Robert I Estienne, known as Robertus Stephanus in Latin and sometimes referred to as Robert Stephens, was a 16th-century printer in Paris. He was the proprietor of the Estienne print shop after the death of his father Henri Estienne, the founder of the Estienne printing firm. Estienne published and republished many classical texts as well as Greek and Latin translations of the Bible. Known as "Printer to the King" in Latin, Hebrew, and Greek, Estienne's most prominent work was the Thesaurus linguae latinae which is considered to be the foundation of modern Latin lexicography. Additionally, he was the first to print the New Testament divided into standard numbered verses.
