Rudolf Jenny

July 26, 1953 - August 10, 2021

left us completely unexpected. A brain hemorrhage tore him from his active, interesting and colorful life. Shocked, we had to let him go. He was buried on Thursday, August 10th, in the presence of his family and closest friends.

In Memory of Rudolf Jenny, the BibliOrchidea Database will remain online and freely accessible. However, there will be no further updates and no copy-on-demand service.

Rudolf Jenny nearly finished the Gongora Monography together with Günter Gerlach, and the book will be available in 2022 in the online shop.

For urgent requests, please contact lorenz.jenny@gmx.ch.
