Louis Pasteur plays a role in the creation myth of biotechnology which resembles the heroic position of his great antagonist Liebig in the story of agricultural chemistry. His intellectual development, expressed in a great book, supposedly underlay a revolution in practice. Similarly, biotechnology is conventionally traced back to Pasteur, through whose influence, it has been assumed, ancient crafts were transformed into an applicable science of microbiology. The emphasis on Pasteur's work in the history of biotechnology has served to bolster the (...) image of progress in the technology following from periodic scientific breakthroughs. Elsewhere I have argued that biotechnology can be better seen as a boundary object, to use Star and Griesemer's terminology, between biology and engineering. As such it has been significant throughout this century, and the word has been used since 1917. (shrink)
