In 1833, Marcus Samuel decided to expand his London business. He already sold antiques but decided to try selling oriental seashells as well, capitalizing on their popularity in the interior design industry at that time. The demand was so great that he began importing the shells from the Far East, laying the foundations for an import-export business that would ultimately become one of the world’s leading energy companies. Nowadays, Shell becomes a global group of energy and petrochemical companies with more than 80,000 employees in more than 70 countries. We use advanced technologies and take an innovative approach to help build a sustainable energy future.
