In 1960, Eugene R. Black, a former president of the World Bank, gave the following description: "The development diplomat must fill the gap between the conventional diplomat and the trader and the investor. His aim should not be commercial or strictly economic; but neither should he be concerned with the narrow political objectives that sometimes overburden the regular diplomat The development diplomat should be a man with a vocation, rather than a man with immediate terms of reference. As an artisan of economic development he should use the tools of economics and other disciplines as best he can to place in perspective to shed light on and to illuminate the choices before the decision-makers in the underdeveloped world". Though this description sounds somewhat romantic, it reflects the unusual challenge and attraction for those working in the field of aid. They are guided by the satisfying feeling of contributing to the improvement of the economic and social condition of the host country.
