Steen Malte Willadsen (born 1944 in Copenhagen, Denmark) is a scientist credited with being the first to clone a farm animal using nuclear transfer. [ [http://library.thinkquest.org/24355/data/details/profiles/willadsen.html Scientist Profile : Steen Willadsen ] ]

Willadsen attended the Royal Veterinary College of Copenhagen and obtained a degree in reproductive physiology. [ [http://library.thinkquest.org/24355/data/details/profiles/willadsen.html Scientist Profile : Steen Willadsen ] ] In 1984, at the British Agricultural Research Council's Unit on Reproductive Physiology and Biochemistry, Willadsen successfully used nuclear transfer to clone a sheep from embryonic cells.
