John Blacking

He is best known for his 1973 monograph ''How Musical is Man?'' in which he argued that the activity of making music is fundamentally important to humans, dependent on society and culture, but separate from the Western musical traditions and standards. He argued that music making was important to developing senses and emotional sensibility and that it is essential for balanced action and effective use of the intellect.
In 1969 Blacking and his then girlfriend and future wife, Dr. Zureena Desai, were arrested by the South African government and charged with violating apartheid's Immorality Act. Blacking was white, Desai was Indian, and the racial purity law forbade relations between different races. The arrest was motivated in part by Blacking's anti-apartheid activism. The trial received worldwide attention and embarrassed the government. The couple were found guilty and given suspended sentences, but Blacking was later banned from South Africa.
