Summary

American banker who built Citigroup through decades of aggressive acquisitions, pioneering the financial supermarket model — and mentored Jamie Dimon before famously firing him.

Core Contribution

Assembled the largest financial services conglomerate in history through serial acquisitions including Travelers Group and Citicorp, and successfully lobbied for the repeal of Glass-Steagall, enabling commercial and investment banking to merge.

Key Spikes & Highlights

  • Acquisition as Identity (built entire career by buying and integrating financial companies — never started anything from scratch, treating M&A itself as the creative act)
