Career
Eggstein lived and worked as a brewer in his home town of Burgau. The Bavarian Constitution of 1818 set up an elected popular assembly for the Kingdom of Bavaria, known as the Bayerische Ständeversammlung, based in Munich and consisting of a chamber of Imperial Councillors and a chamber of deputies. Eggstein was elected in the very first elections in December, chosen from the fifth class and representing the Upper Danube area (Oberdonaukreis) in the chamber of deputies.
The deputies came to the Landtag"s grand opening in Munich on 1st February 1819.
The sessions lasted until the end of the parliament on 25 July 1819 and its legislative term as a whole lasted until 1825, with its members usually only in the chamber when summoned and otherwise back in their home towns working on their regular jobs. In 1819, during his first period at the Landstag from 1819, Eggstein had rented a room at the Gasthof Döllerer in the Tal district of Munich.
There he suffered an erysipelas on the head and died suddenly in his room on 13th March 1819. The funeral service was a Roman Catholic one, led by a priest from the Munich Frauenkirche and with a eulogy at the graveside by the Landtag"s chaplain Pastor Carl Borromäus Egger (1772–1849), a then-popular preacher and writer
Directly behind the coffin walked vice-president count Franz Erwein von Schönborn-Wiesentheid from the counselors" chamber and president Freiherr Sebastian von Schrenck from the chamber of deputies.
Eggstein had been in the Burgau militia since 1803, reaching the rank of Hauptmann and so was buried in his uniform and with a company of the Munich militia as funeral escort.
