In silent mourning we say goodbye to Mr.

Dr. Peter F. Heilmayr

Chemist, Inventor, Entrepreneur and longtime partner and friend of Theysohn Group

Born 12th August 1933, Salzburg, Austria

Died 18th August 2020, Virginia, USA


Mr. Heilmayr was a pioneer in the plastics industry, an inspirational and fascinating friend and business partner.

We are grateful for decades of cooperation and will miss him deeply. Our thoughts are with his family.
