Daisaku Ikeda (Wikipedia)

Wikipedia's own article on Daisaku Ikeda, a tertiary encyclopedic source, consulted here only for his lifespan years, born 1928, died 2023, alongside the scholarly monograph this atlas already holds specifically about him (Seager, Encountering the Dharma) for everything else. Its strength for this narrow purpose is that his birth and death dates are uncontested biographical facts, reported identically by Soka Gakkai's own organization and by independent news coverage of his death. Its limit is the ordinary one for a crowd edited tertiary source on a subject with an organized following: coverage of his leadership record and legacy needs a source with more editorial distance, which is why this citation is confined to dates.
