1908 |
William Castle opens Harvard's Bussey Institution, where many early mouse geneticists, including Clarence Cook Little, get their start. |
|
|
1909 |
C.C. Little begins to develop the first inbred mouse strain, designated DBA for dilute, brown, and non-agouti. |
|
|
1921 |
Using a pair of black mice from the Granby farm, C.C. Little develops the C57BL and C57BR strains. C57BL/6J (“Black Six”) will become the world’s most essential inbred strain. |

1935 |
The first successful transfer of fertilized ova is achieved by Elizabeth Fekete. |
|
|
1936 |
Jackson Laboratory researchers (in the world's first group publication) announce the first link between cancer and viruses in mammals. This leads to the discovery of a cancer-causing virus passed through breast milk, a key finding for the later understanding of oncogenes and cancer. |
|
|
1937 |
Peter Gorer shows in mouse studies at Jackson that transplant rejection is primarily governed by what he calls the H2 genetic locus, later described as the major histocompatibility complex, a key component of immunity. |
|
|
1940s |
The first successful transplantations of ovaries between female mice are performed by Dr. William Russell. |
|
|
Late 1940s |
George Snell develops congenic strains of mice—identical but for a small chromosomal segment—by breeding for differences only at the H2 locus. This opens new areas of immunological research and earns Snell a Nobel Prize in 1980. |
|
|
1950 |
The obese (ob) mouse is discovered by Margaret Dickie. The first animal model for obesity, the mouse later proves to have a key mutation in the leptin gene. |
|
|
1954 |
Leroy Stevens develops an ovary transplant procedure that enables mutant strains to be propagated even if the mutation prevents the animal from living long enough to reach reproductive age. |
|
|
1958 |
Margaret Green starts a card-file database of mouse linkages and loci, forming the foundation of the Mouse Genome Database. Eventually, the National Institutes of Health begins supporting the database. |
