Carl Lewis Hamilton (February 23, 1888 – May 27, 1946) was a prominent American entrepreneur recognized for his leadership position at the Weyerhaeuser timber company and as a founding partner of the consulting firm Booz Allen Hamilton, specializing in management and information technology.

Biography

Hamilton was born in Dubuque, Iowa and completed his Bachelor of Science degree in forestry at the University of Minnesota in 1911. At the start of his professional journey, he served as an agent for a timber enterprise based in West Virginia and oversaw lumber operations across Minnesota and Costa Rica.

He began his tenure with Weyerhaeuser in 1915, eventually rising to the roles of vice president and general manager within its General Timber Service Company division. In 1935, Hamilton became a partner at Booz & Fry Surveys, which later evolved into Booz Allen Hamilton. During the period of World War II, he played a crucial role in obtaining defense contracts, including managing personnel for the United States Cartridge Company.

One of Hamilton’s most significant achievements at Booz Allen Hamilton was the creation of the company's first code of ethics, setting foundational standards for corporate integrity that influenced numerous American firms. Throughout his leadership, the firm transitioned from Booz & Fry to Booz, Fry, Allen & Hamilton, then to Booz Allen Hamilton following George Fry’s exit in 1942 and a subsequent rebranding during the mid-1970s.
