Swiss lithography identification

[This] (https://imgur.com/a/r3rd3) is an old print we found hidden under a photograph we bought some time ago. With the help of a redditor we were able to read the description "Schloss Planta bei Meran", but I would love to know who's signature is on the right bottom. Does anyone here have an idea?

We bought a bunch of old frames from an auction website, some of the frames still had old pictures in them and this print was hidden between the photograph and the cardboard backing of the frame. Thank you for your decoding efforts in advance.
