Founding Story
James O. McKinsey was an absolutely brilliant American accounting professor, fiercely innovative corporate strategist, and the profoundly influential founding patriarch fundamentally responsible for architecting the massive McKinsey & Company consulting empire.

In 1926, he relentlessly launched his eponymous firm in Chicago, completely pioneering the highly rigorous discipline of management consulting. By fiercely applying incredibly strict, data-driven accounting principles to high-level corporate strategy, he completely revolutionized how massive industrial enterprises operated. His incredible intellectual legacy and absolute commitment to objective corporate analysis permanently established the absolute bedrock of the world's most dominant strategic consulting monopoly.
