The content of this chapter relates to the issues of philosophy of science and the sociology of knowledge. The main methodological background is the Actor-Network Theory (ANT) that has been developed since the end of the 1970’ by Bruno Latour, John Law and Michel Callona. I am examining written biographies of scientists to draw the conclusion on science as such. Analyzing biography confirms the belief that the conduct of research is rather a collective work not an individual process. The scientist can be recognized through the heterogeneous networks of relations that allow him to act in the particular way and at the same time giving him the opportunity to achieve the purpose. However, on the other hand, networks can bound the process of research. The networks are shaped by the other scientists, but also by factors such as politics, economic interests and material objects.
