Lab milestones

The Roscoe B. Jackson Memorial Laboratory was founded in 1929 by Clarence Cook Little, a Harvard-trained geneticist who had served as president of the University of Maine and the University of Michigan.

Little created the first inbred (genetically uniform) mouse strains and wanted to use them experimentally to establish that cancer was a genetic disease, not an infectious disorder, as was widely thought at the time. He gained initial financial support for the Laboratory from Detroit industrialists Edsel Ford, president of the Ford Motor Company, and Roscoe B. Jackson (for whom the Laboratory is named), president of the Hudson Motorcar Company.

Little chose Bar Harbor as the site for his new research institution because he had successfully brought students to the area for summer field studies in natural history. The Laboratory was built on land donated by Little’s family friend, George B. Dorr.

In 1933 the Laboratory began providing genetically defined mouse strains to the scientific community as experimental models for various human diseases.

In 1963 the Laboratory was renamed The Jackson Laboratory.

Professor John Eppig, Ph.D., a pioneer in developmental and reproductive biology, was elected to the National Academy of Sciences, one of the top honors in American science.


The Jackson Laboratory joins 10 top New York medical and academic research institutes in founding the New York Genome Center. Launched at a ceremony in New York, the NYGC will become one of the largest genomic facilities in North America, providing Jackson researchers with access to vastly increased gene-sequencing capability and expertise.


The Jackson Laboratory established a new Rare and Orphan Disease Center to address conditions that, while individually rare, collectively affect about one in 10 Americans, according to the National Association for Rare Disorders.



A $27 million expansion of the JAX—West facility in Sacramento adds new vivarium space to house and care for genetically defined mice that are provided to the West Coast biomedical research community.


The Jackson Laboratory purchased of the former Lowe’s building in Ellsworth, Maine, securing a 143,000-square-foot building on a 17-acre site for expansion of its Maine operations.


More than 300 scientists, state officials, business leaders and other invited guests marked the start of construction of The Jackson Laboratory for Genomic Medicine in Farmington, Conn.
