Jean-Pierre-Louis Wenger (31 May 1809 in Lausanne – 11 August 1861 in La Vaux, commune of Aubonne) was a Swiss architect and politician from the canton of Vaud.
Upon his return to Switzerland, he started a political career and was a Radical Democratic deputy in the Grand Council of Vaud which he chaired six times between 1846 and 1861.
[1] As an architect, Wenger restored several important monuments such as the Chapel of St. Anthony, La Sarraz, the Reformed Church of Our Lady, Orny, and the rose of the Cathedral of Lausanne.
He may have built the church of Bussigny, but archive sources rather attribute this work to surveyor Samuel Cupelin and architect David Braillard.
[3] His works on healthcare buildings include the Asile des aveugles (Asylum for the blind) and the uncompleted project of a psychiatric hospital.
