title: Reflections on the golden anniversary of the first embryo transfer to produce a calf.
abstract: In the belief that the vitality of a discipline benefits from a knowledge of its roots, events surrounding the first embryo transfer to produce a live calf (by Willett and his colleagues in Wisconsin fifty years ago) have been reviewed. That first success is discussed in the context of those times (including a brief review of the first international conference on embryo transfer, held in Texas in 1949) and in relation to subsequent events that led to the founding of the International Embryo Transfer Society in 1974.
