Schwarz was responsible for sales and marketing at Zschimmer & Schwarz for over 40 years. He actively promoted the internationalisation of the company and opened up new markets and customer segments, especially in North and South America.

He also led the company’s acquisition of its Mohsdorf plant and thus created the link to its historical roots in Chemnitz.

Zschimmer & Schwarz said that Schwarz made a significant contribution to its journey to become an international supplier of chemical specialities and had a decisive influence on the group.

The company said: “Thanks to his kindness and his closeness to customers, business partners and employees, he was always present, lived and helped shape the philosophy and values of our company.

“Our heartfelt sympathy goes out to his wife and family. Together we all mourn the loss of a person whose memory will live on forever.”
