The article portraits the first winner of Nobel price in economics coming neither from America nor from Europe, the Indian thinker Amartya Kumar Sen, with special emphasis on his career since the 1998 prestigious award. Therefore it does not focus primarily on his earlier contributions to mainstream economics, such as the analysis of preferences or the welfare economics. Instead, attention is paid to Sen's activities in the field of development studies including measuring development and poverty, specific understanding of these phenomena and his famous capability approach. At the same time Sen is showed as a researcher able to cross the borders of economic science, to regard the questions that he examines from philosophical, ethical or political aspect as well and to present them in a way accessible not only to specialists but also for broader audience. Last but not least the reader is made familiar with current Sen's professional activities and the most up-to-date impact of his scholarly work.
