The term ?boson? appears in almost all discussions on elementary particles and carries a reference to the name of Satyendra Nath Bose, the co-founder of quantum statistics. Yet, in spite of this wide use of a term coined after his name, Bose himself remains a shadowy figure in the history of science. This article is an attempt to reconstruct how Bose arrived at the statistics for which he is now remembered, and his subsequent two-year brief role in international science. Through (...) the lens of Bose's practice, I seek to grasp the contexts of those peripheral scientists who enter the practice of science from outside of the main group, and yet somehow manage to create a lasting contribution within it.
