His father, Alexander Low Bruce, was a son-in-law of David Livingstone and urged his two sons to use the landholding he had acquired for philanthropic purposes. However, during almost 50 years residence in Africa, Bruce represented the interests of European landowners and opposed the political, educational and social advancement of Africans. After the death of his elder brother in 1915, Alexander Livingstone Bruce had sole control of the company estates: his management was harsh and exploitative, and one of the main causes of the uprising of John Chilembwe in 1915. During the uprising, three of Bruce's European employees were killed and one of them, William Jervis Livingstone was held partly to blame for the revolt. Although Livingstone was carrying out Bruce's orders, Bruce, as a leading landowner and member of the governor's Legislative Council, escaped censure. Despite Bruce's striving for profits, A L Bruce Estates lost money but was saved from insolvency by the colonial government's need for land for resettlement following a famine in 1949.
