The Hsd:ICR (CD-1®) mouse model is of Swiss origin and descended from the original two male and seven female albino non-inbred mice, imported by the Rockefeller Institute in 1926 from Lausanne, Switzerland. Descendants were distributed worldwide and the Ha/ICR was established in 1948 at the Institute of Cancer Research (ICR). A portion of the Ha/ICR colony was given to the Roswell Park Memorial Institute (RPMI). Charles River Laboratories (CRL) received their nucleus from RPMI in 1959, and caesarean rederived. Harlan obtained breeding stock from CRL in 1983. Harlan became Envigo in 2015.
