From Wikipedia:
Hendrik Frensch Verwoerd (1901 – 1966), also known as Dr. H. F. Verwoerd, was a South African professor, newspaper editor-in-chief and politician who was Prime Minister of South Africa from 1958 until his death. He is regarded as the mastermind behind socially engineering and implementing the racial policies of apartheid, the system of legal racial classification and forced racial segregation that existed in South Africa from 1948 to 1994.
Verwoerd played an instrumental role in helping the far right National Party (South Africa) come to power in 1948 serving as their propagandist and political strategist. He eventually rose to party leader in 1958. During his time in office Verwoerd rigidly enforced Apartheid policies through introducing further oppressive laws, which diminished the rights of ordinary individuals, especially black South Africans. He greatly empowered, modernised and enlarged the police, secret police and army. Verwoerd ordered a secret all-out offensive against those who opposed apartheid, which resulted in tens of thousands of people being detained, imprisoned, exiled, tortured or killed (Sharpeville Massacre). Verwoerd was a right wing authoritarian leader and Afrikaner nationalist. He was a strong advocate of the Afrikaner volk, language, culture and Christian religion. He held the belief that white control over South Africa could only continue if the races lived apart. He survived an assassination attempt in 1960, succumbing to a subsequent one in 1966.
