George Alexander Graham Adamson MBE (3 February 1906 – 20 August 1989), also known as the Baba ya Simba ("Father of Lions" in Swahili),[1] was a British wildlife conservationist and author based in Kenya.

George Alexander Graham Adamson was born on 3 February 1906 in Etawah, India[2] to English and Irish parents.

He was educated at Dean Close School, Cheltenham, England, and moved to work on his father's coffee plantations in Kenya in 1924.

Adamson retired as a Senior Wildlife Warden of the Northern Frontier District Province of Kenya (Meru National Park area) in 1961 and devoted himself to raising lions that could not look after themselves and training them to survive in the wild.

In 1970, he moved to the Kora National Reserve in northern Kenya to continue the rehabilitation of captive or orphaned big cats for eventual reintroduction into the wild.
