Biographical research in sociology is usually carried out by means of in-depth interviews where people are asked to tell their life histories or experiences in a given stage of life and/or dimension of existence. Occasionally, secondary materials such as photographs, letters, timelines or life calendars are also used to complement the narrative. In both cases the focus is on first person testimonies, assuming that the information collected through these procedures provides a more direct and reliable access to the events and subjectivity of the life course. Much less explored is the possibility of reconstituting a biography not only in this way, but also on the basis of testimonies of third parties, specifically close people who can talk about the trajectories of the individual being analysed and about the relation they have with that person. What we intend to do in this project is precisely to understand how biographies can be reconstituted and analysed through multiple testimonies, using triangulation and comparison of sources of information. Mobilising a qualitative methodology, by means of biographical interviews, the aim is to comprehend how a person describes and ascribes meanings to her/his life, but also how close people perceive, present and interpret that biographical pathway. Twenty biographies will be analysed, each case being composed of the interview with the nuclear person and about four interviews with her/his family members, friends, colleagues or neighbours (of different kinship, generations, life contexts).

Thus, it is intended to articulate an internal perspective with an external one on the same person and respective biography. This analytical strategy enables the study of the temporal, social and relational constitution of a biography, in line with the typical analytical fra...
