Birth name

Robert Jonathan Demme is listed in LOC authorities (Demme, Jonathan, 1944–2017) and obituaries (LOC; Telegraph obituary). He was professionally known as Jonathan Demme, dropping the first given name in billing.

From Corman to Oscars

Demme apprenticed in Roger Corman productions, then directed Melvin and Howard, Stop Making Sense (Talking Heads concert film), Something Wild, Married to the Mob, The Silence of the Lambs (1991)—which won the "Big Five" Oscars including Best Director—and Philadelphia (1993). Later work ranged from remakes to documentaries and music films (Britannica students; LOC).

He died in April 2017 from complications related to esophageal cancer and heart disease, per contemporary obituaries. Memorials stressed his humanism and musical taste as much as the thriller that won the Academy's top prizes.

Why the "real name" question matters

Search interest in a celebrity's "real name" usually means one of three things: a shortened everyday form (Tom for Thomas, Dave for David), a middle name used as a stage handle (Drake-style), or a true legal/professional change after immigration or branding. This sprint page states which case applies, cites library or encyclopedia authorities where possible, and avoids gossip. Career sections stay high-level and sourced so Domain Bot can add internal/external links without rewriting the biography. Living subjects are limited to public facts; memorials avoid graphic detail.
