When Emperor Franz I was living at Schloss Heusenstamm in 1764 on the occasion of his son's coronation (Goethe relates the event in his "Dichtung und Wahrheit"), an ostentatious tower was built in his honour, which stands to this day. In 1806, the Schönborn "Amt" of Heusenstamm with Obertshausen and Hausen was put under the Princes of Isenburg-Birstein. The "Amt" of Heusenstamm then passed to the Hesse-Darmstadt. In 1819, when the Biebermark was partitioned, Heusenstamm got its share of the forest. In 1896, the railway line from Offenbach by way of Heusenstamm to Dietzenbach, a branchline of the "Rodgaubahn" from Offenbach to Dieburg, was opened.
