Johannes Buxtorf the Younger, (August 13, 1599 – August 16, 1664) was son of the scholar Johannes Buxtorf, and a Protestant Christian Hebraist.
Buxtorf was born in Basel, where he also died. Before the age of thirteen he matriculated at the University of Basel, and in December 1615 graduated as Master of Arts there. He went to Heidelberg, where he continued his studies under David Pareus, Abraham Scultetus, Johann Heinrich Alting, and others.
In 1618 he attended the synod of Dort, where he formed friendships with Simon Episcopius, Ludwig Crocius, and others. He succeeded his late father, in the chair of Hebrew at the university; he gained an almost equal reputation, in the same domain, and was considered a chip off the old block. Although he received offers from Groningen, Leyden, and other places, he preferred to retain his position at Basel. He was four times married, and in his latter years experienced many sorrows.
Like his father, Buxtorf maintained relations with several learned Jews. He employed Abraham Braunschweig to purchase Hebrew books for him; and for many years he corresponded with the scholarly Jacob Roman of Constantinople regarding the acquisition of Hebrew manuscripts and rare printed works. Buxtorf was also engaged in the sale of Hebrew books; among his purchasers being the commercial representative of Cardinal Richelieu, Stella de Tery et Morimont, who occasionally sojourned at Basel, and Johann Heinrich Hottinger at Zurich, with whom Buxtorf was on terms of close friendship. He also frequently furnished Hebrew books to the Zurich library.
