son of the preceding, and, like him, an eminent Hebraist, was born Aug. 13, 1599. Taught by his father, he made great proficiency in youth. In 1630 he was made Hebrew professor at Basle; 1647, professor of controversial theology; and 1654, of Old Test. literature. He is best known for his defense of his father's notions on the antiquity of the vowel points in Hebrew, which appeared in his Tractatus depunctorum, vocaliun, et accentuum origine et auctoritate (Basle, 1648), and other works. On this subject he had a bitter controversy with Capellus (q.v.). Besides other works, he published Lexicon Chaldaicum ct Syriacum (Basle, 1622, 4to). He died Aug. 16, 1664.
