HEMSTERHUIS, TIBERIUS (1685-1766), Dutch phil ologist and critic, was born on Jan. 9, 1685, at Groningen in Hol land, and died at Leyden on April 7, 1766. He was professor of Greek at Franeker from 1717 to 174o, and then at Leyden, and was also a mathematician and philosopher. In 1706 he completed Lederlin's edition of Pollux's Onomasticon. This was widely admired, but he was much mortified by the criticism of Bentley. Hemsterhuis was the founder of a laborious and useful Dutch school of criticism, which had famous disciples in Valckenaer, Lennep and Ruhnken.
