In Memory

Martin Weinberg: Xamax Founder, President, CEO and Chief Inventor
Engineer | Entrepreneur | Inventor | Leader

Martin Weinberg joined Sterling Paper as a student engineer. He led manufacturing and product development for fifteen years before leaving to found Xamax Industries in 1992. Martin later merged the two companies and grew Xamax Industries from a US focused company providing electrical insulation to a global company producing industrial, consumer and technical products. Martin lived his philosophy ‘Imagination Becomes Reality’ by making it his daily practice: writing dozens of patents and creating inventive products to solve customer problems.

Martin taught his colleagues, both internally and externally, many lessons:

1. Create your own path; 2. Live fully and appreciate life; 3. Give willingly; 4. Don’t give up, be creative finding solutions; 5. Be curious and keep learning; 6. Take risks

Martin fought cancer heroically, patiently, diligently. His body succumbed in October 2018 yet his spirit will continue to infuse Xamax’s vision, culture, products and customer service. His family remains committed and engaged with Xamax. All of us at Xamax are dedicated to continuing Martin’s legacy, living his values, remaining devoted to our colleagues and partners and building on the strong foundation he built.
