Alexander Sigismund von der Pfalz-Neuburg

Alexander Sigismund von der Pfalz-Neuburg (1663–1737) was the Prince-Bishop of Augsburg from 1690 to 1737.

A member of the House of Wittelsbach, Alexander Sigismund von der Pfalz-Neuburg was born in Neuburg an der Donau on 16 April 1663, the fifth son of Philip William, Elector Palatine and his wife Landgravine Elisabeth Amalie of Hesse-Darmstadt.

He was destined for the clergy from a young age, and was sent to study with the Jesuits in Neuburg an der Donau and Düsseldorf.

[2] In 1714, Alexander Sigismund suffered a bout of mental illness, and the cathedral chapter of Augsburg Cathedral selected Johann Franz Schenk von Stauffenberg, Bishop of Constance, to be coadjutor bishop on 11 June 1714.

[3] Alexander Sigismund finally recovered enough to resume his duties as Prince-Bishop in 1718.
