Jean Blondel’s academic impact in the field of comparative governments was enormous, but difficult to measure. Over the past 60 years, his publications have fuelled the work of several generations of colleagues around the world. In this short essay, we first introduce his most influential publications. Second, we introduce the empirical findings of major comparative studies which stand ‘on the shoulders’ of his research on governments and ministers in parliamentary democracies. Overall, we state that Jean Blondel’s comparative research was not designed to leave behind an enduring theory of his own. Instead, he was more interested in looking for more unexpected measurable facts and merge them into generalizations about the future of cabinet governments and political leaders.
