Günümüzde indükleme olarak bilinen süreci bulmuş ve bu buluşuyla 1935 Nobel Fizyoloji veya Tıp Ödülünü almıştır. Hans SpemannBorn: 27-Jun-1869 Birthplace: Stuttgart, Germany Died: 9-Sep-1941 Location of death: Freiburg, Germany Cause of death: unspecified Gender: Male Race or Ethnicity: White Occupation: Scientist Nationality: Germany Executive summary: Experimental embryology Military service: German Army (1889-90) Sometimes called "the father of cloning", German scientist Hans Spemann conducted primitive cloning experiments and studied how embryo cells develop. In his earliest experiments, he split the cells of a two-celled salamander embryo into two parts, successfully producing two larvae.
