His daughter, Teresa Campbell, also recalled, "My father was born and bred among the natives of South Africa. He got to love their wisdom and integrity. He respected them tremendously - to him they became as brothers. He spent all his happy childhood years with them and learnt a lot about life from this close association. It was this deep sharing of life with him that gave him his clear insight to the South African problem. We were always surprised at the uncommon ease with which he could mix with any company - with peasants and fishermen. This, my mother said, came from his early mixing with the native Africans."
