A pioneer in experimental embryology, Ross Granville Harrison made numerous discoveries that advanced biology. One of the most significant was his adaptation of the hanging drop method from bacteriology to carry out the first tissue culture. This method allowed for further studies in embryology as well as experimental improvements in oncology, virology, genetics, and a number of other fields. Prior to Harrison's innovation, a number of scientists, including Julius Arnold, Gustav Born, Leo Loeb, and Gottlieb Haberlandt, had attempted to grow tissues in isolation in vitro and in vivo but with much less success than Harrison. In addition, Harrison contributed to the understanding of organization and differentiation.
