This contribution commemorates Geert Hofstede, who recently passed away, as a pioneer in the study of culture and institutions. It does so by touching on some of the details of his personal life and connecting these with his professional career. The latter was devoted to developing the paradigm of national cultures based on empirical analysis, and to relate it to organisational behaviour. Closer scrutiny reveals that four distinct phases may be identified. Hofstede first started as an ‘undercover’ engineer and next moved to social psychology. During the second phase, he developed the first four dimensions of natural culture. During the third, Hofstede connected these national dimensions to organisational ones. During the last, he added two new cultural dimensions and developed additional practical applications. Finally, the article considers the reception, criticism, and further elaborations of Hofstede's contributions.
