Marvin Bower (August 1, 1903 – January 22, 2003) was an American business theorist and management consultant associated with McKinsey & Company.

Under Bower's leadership, McKinsey grew from a small engineering and accounting firm to a leader in the consulting industry.

"[1][2][3] Bower was the son of the deputy recorder at Cuyahoga County, and grew up in the Collinwood neighborhood of Cleveland, Ohio and attended Glenville High School.

According to Harvard Business School,[1] Bower "is considered the father of modern management consulting" for his decades of work at McKinsey.

"Let me just say there was a shock on people's faces when he told us that he was selling his shares back to McKinsey at book value," said his son Dick Bower.
