With 70 facilities in 18 countries, Charles River Labs partners with leading pharmaceutical, biotechnology, government, and academic organizations around the world to provide products and services that span all stages of drug discovery and development.

The company is focused on providing clients with exactly what they need to improve and expedite the discovery, development through first-in-human evaluation, and safe manufacture of new therapies for the patients who need them.

For 2009, the company reported net sales fell by 10.5% to $1.2 billion. The company had net income of $112.6 million.


In 1947, Dr. Henry Foster, a young veterinarian, founds Charles River Breeding Laboratories in Boston, MA with the goal of supplying the research community with a new standard of laboratory animal models. He purchased several thousand rat cages for $1,200 from the Sunny Hill Rat Farm in Virginia and set up a lab in a second floor loft overlooking the Charles River on Leverett Street in Boston, MA.

It is a one man-company: Dr. Foster handles the breeding, feeding and husbandry tasks himself. He takes orders by phone, packs the animals and personally delivers them to his clients. This work is conducted under the company name, Charles River Breeding Laboratories.

In 1955, Dr. Foster moves his company to Wilmington, MA to a remodeled ranch-style house sitting on 42 acres of land. As customer demands grow, so does the business, making it necessary to rebuild the site to accommodate offices for Customer Service, Company Executives, and Administration.

Dr. Foster secures a $100,000 loan from the Small Business Administration to begin commercial production of pathogen-free rodents. He uses flexible film isolators developed by pioneer Philip Trexler, Associate Director of the Lobund Institute of the University of Notre Dame. Trexler taught the major suppliers of lab animals how to derive their animal stocks and strains into the “germ-free” or axenic state, thereby freeing them of the numerous infectious disease agents plaguing biomedical research.

Charles River would also develop non-pathogenic bacteria in 1955 to inoculate animals and reinforce digestive and immune responses.

The company went public on the NY Stock Exchange in 2000. Sales surpassed $1 billion in 2005.
