Who is known for studying the people of the Trobriand Islands and was revolutionary in the field for using Participant Observation Techniques?

Bronisław Malinowski

Explanation:

Participant observation is a method of research in which the researcher joins the activities of the group under study in a bit to observe them. The researcher here can make a trip of two year and work with the native community being studied.

This method was brought into the study of anthropology after the nineteenth century by Bronislaw Malinowski because the people conducting research studies at that time prefer to do that from the balcony of a missionary station. In order to realize what he feels about his world, Malinowski studied the Trobriand Islands using this method.
