Bude (Buttons), Guillaume, a French scholar, born in Paris in 1467, died Aug. 23, 1540. He studied philosophy, mathematics, and the Greek language, the latter under Lascaris. In 1519 he published the Commentarii Lingum Grcecce, which gave an impulse to the study of Greek literature in France. He was also engaged in public affairs under Louis XII. and Francis I. He persuaded Francis not to issue an edict prohibiting the printing -of books, which had been urged by the Sorbonne. The royal college of France and the royal library at Fontainebleau were founded through his efforts. At the time of his death he was royal librarian. He was suspected of Calvinism, and after his death his family openly espoused the reformation. After the massacre of St. Bartholomew they were obliged to flee from France. A part of them went to Switzerland, retaining their original name of Bude; among the possessions which they there acquired was the estate of Ferney, afterward occupied by Voltaire, though still owned by the Bude family.

Another branch emigrated to Pomerania, where they assumed the name of Budde, Latinized into Buddeus. (See Buddeus).
