The article – focused on the exploration of the meanings of transgenerational scientific biographies – is a form of a dialogic conversation occurring between two members of the society of Łódź pedagogues. He – emerged in this society as a newcomer arriving from the world of anthropology and ethnography. She – a social pedagogue –made her way there from the circle of the family social work field. In spite of having different disciplinary origins, carrying on a dialog gives them a chance to recognize the paths indicating the existence of their common intellectual and experiencerelated connections. Using these common links, they work together on the interpretation and gradual detection of the signs of unacknowledged past, where ethnography and social pedagogy meet the foundations set by Helena Radlińska and Kazimiera Zawistowicz-Adamska.
