""The period before World War I led to the initiation of inbreeding in rats by Dr Helen King in about 1909 and in mice by Dr C. C. Little in 1909. The latter project led to the development of the DBA strain of mice, now widely distributed as the two major sub-strains DBA/1 and DBA/2, which were separated in 1929-1930. DBA mice were nearly lost in 1918, when the main stocks were wiped out by murine paratyphoid, and only three un-pedigreed mice remained alive. Soon after World War I, … " - Inbreeding mice
