Sigmund Freud

Published The Interpretation of Dreams in 1899, a documented, genuinely novel theoretical synthesis at the time, independently attested by the scale of the field — psychoanalysis — that developed directly from it.

Conducted his own systematic self-analysis through daily dream recording over several years while simultaneously maintaining a full clinical practice and prolific writing output, documented in his letters to Wilhelm Fliess.

Ended his collaborations with Carl Jung and Alfred Adler at specific, dated points once he judged their theoretical departures irreconcilable, following extended periods of documented ambivalence beforehand.

This is consistent with the profile's high autonomy_need and low collaboration score: a documented, repeated pattern of prioritizing theoretical control over preserving close working relationships. Need for Autonomy

The Interpretation of Dreams sold poorly for years after publication and psychoanalysis was widely dismissed by the medical establishment for over a decade, documented in his own correspondence describing sustained professional isolation.

Fled Nazi-annexed Vienna for London in 1938, at 82 and after 33 operations for the cancer first diagnosed in 1923, specifically to continue his work and protect his papers and his daughter Anna.

This matches the profile's high persistence and impact_motivation: continued, self-directed work pursued under severe physical and political threat rather than abandoned for safety alone. Persistence
