Why the line attaches to great men
The adage warns against thinking anyone is irreplaceable. That makes it a natural fit for a towering leader, which is probably why it ended up on Clemenceau and then de Gaulle. Buchanan’s 1981 column used it in a piece titled “The Indispensable Man – Reagan.”
The documented record is humbler. The idea first shows up as an unsigned filler line in a small American magazine, then passes through newspaper columns and parliamentary banter for decades before the “indispensable men” wording settles.
Glasnevin Cemetery is full of indispensable people.
Was there a French version?
QI notes that a 1948 English translation of Jacques Nels’s novel A Man of Means contains “The cemeteries are full of indispensable people.” It says this makes it possible that a French version existed early. QI also notes it had not yet checked that citation on paper (Quote Investigator ↗). Even so, no source ties the line to de Gaulle himself.
