Franz Erwein, 1st Count of Schönborn-Wiesentheid (4 April 1776 – 15 December 1840) was a German art collector and politician from the House of Schönborn.

His parents were the Hugo Damian Erwein von Schönborn-Wiesentheid (1738–1817), a chamberlain and member of the counsel from Aschaffenburg, and his wife Maria Anna (1746–1817), who had been countess of Stadion zu Thannhausen und Warthausen.

As a result, Franz Erwein von Schönborn mainly focused on administering his Frankish estates and those in the wine-growing areas of Rheingau.

The column was designed by Schönborn's friend Leo von Klenze and commemorated Maximilian I Joseph's 1818 grant of a Constitution to the Kingdom of Bavaria.

Fernandine, who was from Hildesheim, was the daughter of the Imperial Count Clemens August von Westphalen zu Fürstenberg (sole heir of his maternal great-uncle, Prince-Bishop of Paderborn William Anton of Asseburg, and his paternal uncle, Prince-Bishop of Hildesheim Friedrich Wilhelm of Westphalia) and Countess Maria Antonia Waldbott von Bassenheim.
