He was born in Mühldorf, Austria, in 1922. From 1946 to 1950, he attended the Art School in St. Gallen and mainly engaged in making stone reliefs. In 1952, he discovered the vocation of a sculptor and began working for public institutions such as schools, churches, community centres and hospitals.
Wyss’s artwork is quite diverse and ranges from figurative sculpture to geometric, abstract sculpture. However, his art is very personal and often deals with the relationship of man and woman, life and death. The influence of archaic and prehistoric art can be discerned in his works, which are extremely expressive and recognizable by their meticulous, careful stone processing. Wyss took part in several international sculpture symposium. His works are exhibited in many public places in Switzerland. He received several awards and recognitions for his work.
He died in Zurich, Switzerland, in 2005.

He participated in the Mediterranean Sculpture Symposium in 1983.
