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:
“What would we not give for some great poem to read now, which would be in harmony with the scenery,for if men read aright, methinks they would never read anything but poems. No history nor philosophy can supply their place.”
—Henry David Thoreau (18171862)
“A people without history
Is not redeemed from time, for history is a pattern
Of timeless moments.”
—T.S. (Thomas Stearns)
“There is a history in all mens lives,
Figuring the natures of the times deceased,
The which observed, a man may prophesy,
With a near aim, of the main chance of things
As yet not come to life.”
—William Shakespeare (15641616)
