History
In 1974 Rudolf Jaenisch created the first genetically modified animal by inserting a DNA virus into an early-stage mouse embryo and showing that the inserted genes were present in every cell. However the mice did not pass the transgene to their offspring. In 1981 the laboratories of Frank Ruddle from Yale, Frank Constantini and Elizabeth Lacy from Oxford, and Ralph Brinster and Richard Palmiter from University of Pennsylvania and University of Washington injected purified DNA into a single-cell mouse embryo and showed transmission of the genetic material to subsequent generations. During the early eighties the technology used to generate genetically modified mice was improved into a tractable and reproducible method.

Famous quotes containing the word history:
“All things are moral. That soul, which within us is a sentiment, outside of us is a law. We feel its inspiration; out there in history we can see its fatal strength.”
—Ralph Waldo Emerson (18031882)
“The history of his present majesty, is a history of unremitting injuries and usurpations ... all of which have in direct object the establishment of an absolute tyranny over these states. To prove this, let facts be submitted to a candid world, for the truth of which we pledge a faith yet unsullied by falsehood.”
—Thomas Jefferson (17431826)
“At present cats have more purchasing power and influence than the poor of this planet. Accidents of geography and colonial history should no longer determine who gets the fish.”
