Eduard C. Lindeman in the context of "Participant observation"

Participant observation is one type of data collection method by practitioner-scholars typically used in qualitative research and ethnography. This type of methodology is employed in many disciplines, particularly anthropology (including cultural anthropology and ethnology), sociology (including sociology of culture and cultural criminology), communication studies, human geography, and social psychology. Its aim is to gain a close and intimate familiarity with a given group of individuals (such as a religious, occupational, youth group, or a particular community) and their practices through an intensive involvement with people in their cultural environment, usually over an extended period of time.

The concept "participant observation" was first coined in 1924 by Eduard C. Lindeman (1885-1953), an American pioneer in adult education influenced by John Dewey and Danish educator-philosopher N.F.S.Grundtvig, in his 1925 book Social Discovery: An Approach to the Study of Functional Groups. The method, however, originated earlier and was applied in the field research linked to European and American voyages of scientific exploration.
