The Mérieux Legacy


Following in Pasteur’s footsteps, Marcel Mérieux, who studied under Louis Pasteur and Emile Roux, established Institut Mérieux in 1897.

Initially under the direction of Dr. Charles Mérieux (Marcel’s son) and later Alain Mérieux (Marcel’s grandson), Institut Mérieux became a world leader in the field of human and veterinary vaccines.

The family's corporate holding was later extended in the 1990s to address food safety and nutrition issues, through the acquisition of American food testing company Silliker. It was this acquisition which later resulted in Mérieux NutriSciences. 

Silliker is the historical pillar of Mérieux NutriSciences and a pioneer in the field of food safety and quality. The company was created in 1967 in the United States by Dr. John H. Silliker, a microbiologist known for his work on Salmonella, who began his own business with a staff of just four people.
