Susanne Wenger MFR, also known as Adunni Olorisha (4 July 1915 – 12 January 2009), was an Austrian-Nigerian artist and Yoruba priestess
who expatriated to Nigeria. Her main focus was the Yoruba culture and she was successful in building an artist cooperative in Osogbo. She partnered with local artists in Osogbo to redevelop and redecorate the Osun Osogbo Sacred Grove with sculptures and carvings depicting the various activities of the Orishas.
Wenger was a leading advocate for the preservation of the Osun Grove. Due to her efforts, the grove was made a national monument in 1965, and was later marked as a world heritage site.
