Origins thumb|right|200px|ONUDI in French and Spanish The origins of the United Nations Industrial Development Organization (UNIDO) can be traced to a series of studies on a programme of rapid industrialization of developing countries that the United Nations Secretariat carried out during the early 1950s at the request of the United Nations Economic and Social Council (ECOSOC). These studies culminated in a programme of work on industrialization and productivity prepared by the United Nations Secretary-General in 1956 and endorsed the next year by ECOSOC and the General Assembly. At that time, it was first suggested that a special body to deal with the problems of industrialization be established, whose political organs could relieve ECOSOC and the General Assembly of the detailed consideration of those questions and whose secretariat could carry out more substantive work than the existing Industry Section of the Bureau of Economic Affairs within the Secretariat. The Industry Section of the Secretariat became a branch in 1959, and in 1962 it became the Industrial Development Centre, headed by a Commissioner for Industrial Development.
