Does Halbwachs's collective-memory framework feed directly into Portelli's oral-history method, or did Portelli arrive independently?

claim-halbwachs-collective-memory-is-shared-ancestor-of-interpretive-forgetting claims Maurice Halbwachs's 1925 collective-memory theory is the shared theoretical ancestor of both Foroughi & Al-Amoudi's interpretive organizational forgetting and Alessandro Portelli's oral-history method. The Foroughi & Al-Amoudi lineage is reasonably well attested (their paper is described as explicitly Halbwachs-framed, though see question-verify-foroughi-al-amoudi-2020-primary-quote for the quote itself). The Portelli lineage is not: no primary text confirms whether Portelli cites Halbwachs directly, or arrives at collective-memory-as- reconstruction independently through oral-history practice, uninformed by Halbwachs's sociology.

What to read. Portelli's own methodological writing — The Death of Luigi Trastulli and Other Stories (SUNY Press, 1991), especially its introduction/methodology essay, or his other collected essays on oral history method — for any citation of Halbwachs or Les cadres sociaux de la mémoire.

Note. This question is downstream of question-verify-portelli-trastulli-primary, which is also blocked on reading Portelli's primary text (that one on the 1949→1953 date displacement specifically). Once a Portelli primary is in hand for either question, check both at once rather than fetching it twice.

On success. If direct citation is confirmed, clear the [unverified-mechanism] flag on the Halbwachs claim-note and consider promoting it past seedling. If Portelli demonstrably arrived independently, rewrite the claim as convergent discovery rather than shared lineage — a distinct and equally interesting finding, not a failure.
