Theodor Willem Johannes Juynboll, also Theodorus Willem Johannes Juijnboll, Theodorus Guiliemus Johannes Juynboll (April 6, 1802 in Rotterdam – September 16, 1861 in Leiden) was a Dutch Reformed theologian and oriental philologist.
Theodor Juynboll was the son of Gualterus Johannes Juynboll and Catharina Johanna Pla. After his mother died early in his childhood, his father married Johanna Deel and the family moved to The Hague where Theodor attended Latin school. In 1821 he enrolled in theology and Semitic languages at the University of Leiden under Hendrik Arent Hamaker (1789–1835) and Johannes Hendricus van der Palm. He was awarded a honorary mention in the academic competition of the University of Leuven in 1824. In 1828 he earned his doctorate of theology.
In 1828, he entered the parish ministry of Voorhout, where he worked as a pastor until 1831 when he succeeded Groenewoud as professor of semitic languages at the Athenaeum in Franeker. He taught Hebrew and Semitic languages and Jewish antiquities and later the Old Testament and Arab writers. He held the Alternate Rectorate of the Educational Institution from 1834 to 1836. In 1840 he became a corresponding member of the Royal Institute of the Netherlands.[1] In the same year he received a royal honor as a professor of Oriental languages and Hebrew history at the University of Groningen.
Juynboll succeeded G. Wolters at the University of Groningen in 1841 and four years later H. E. Weijers in Leiden. As adjudicator he had R. Dozy (1846–1850) and later Pieter de Jong (1859–1861) and de Goeje.In 1845, he received an honorary doctorate of philosophy from the Senate of Groningen University, a professorship at the Faculty of Philosophy, Leiden University, teaching Oriental languages Arabic, Chaldean, Syriac, and Hebrew. In 1853/54, he became rector of his Alma Mater.
Juynboll was a friend and colleague of the orientalist Ferdinand Wüstenfeld. When Juynboll died prematurely, Wüstenfeld continued his translation work of the great geographic encyclopedia, Mu'jam al-Buldan by Yaqut al-Hamawi, on which Juynboll had been editing an abridgement titled, Marâsid al ittilâ.[2]
In 1829, Juynboll married Wilhelmina Eva Verkouteren (1802–1871) at Voorhout. Their son Abraham Wilhelm Theodorus Juynboll (1833–1887) also gained renown as a philologist.
Much of Juynboll's works deal with the history and literature of the Samaritans:
