A third partner, Daniel Robbins joined the enterprise as it grew, and it was renamed McKesson & Robbins following Olcott's death in 1853. McKesson is headquartered in San Francisco, CA.

McKesson successfully emerged from one of the most notorious business/accounting scandals of the 20th century—the McKesson & Robbins scandal, a watershed event that led to major changes in American auditing standards and securities regulations after being exposed in 1938. In the 1960s, McKesson & Robbins merged with Foremost Dairies of San Francisco to form Foremost-McKesson Inc.
