Umm Kulthum c. 1898 - 1975 · Egypt
Umm Kulthum was an Egyptian singer. She was probably the most famous Arab cultural figure of the 20th century. She was born around 1898 in a small village called Tamay az-Zahayra, in the Egyptian Nile Delta. Her exact date of birth is uncertain, partly because village births were not always carefully recorded. Her father was a village imam, a Muslim religious leader. He led prayers and sometimes sang religious songs at weddings to earn extra money. He noticed that his young daughter had an extraordinary voice. He taught her to sing religious songs and then took her with him to perform. To make this socially acceptable in conservative villages, she dressed as a boy when she sang in public. She was known as 'the boy with the strong voice'. In the 1920s she moved to Cairo, the capital and cultural centre of Egypt. She took singing lessons, dropped the boy disguise, and quickly became a star. Egyptian radio began broadcasting her concerts in the 1930s. By the 1940s she was the most famous singer in the Arab world. She gave a concert on the first Thursday of every month for decades. Across the Arab world, streets emptied as people gathered around radios to listen. She sang for kings, presidents, and ordinary villagers. She supported Egyptian independence and President Gamal Abdel Nasser. After Egypt lost the 1967 war with Israel, she gave concerts across the Arab world to raise money for the country. She died in 1975. Around four million people attended her funeral in Cairo, one of the largest in human history.
"Sing a beautiful song with a strong meaning, and the people will love you."
Margaret Mead 1901-1978 · United States
Margaret Mead (1901-1978) was an American cultural anthropologist who became the most publicly prominent and widely read anthropologist of the twentieth century. She was born in Philadelphia and studied at Barnard College before completing her doctorate under Franz Boas at Columbia University. In 1925, at the age of twenty-three, she travelled to American Samoa to conduct fieldwork on adolescence — a period of turmoil in Western culture that many assumed was biologically inevitable. She wanted to test whether this turmoil was universal or culturally specific. Her book Coming of Age in Samoa (1928) argued that adolescence in Samoa was a calm and untroubled transition, suggesting that the storm and stress of Western adolescence was a product of culture, not biology. The book became an international sensation. She went on to conduct fieldwork in Papua New Guinea, Bali, and elsewhere, writing influential books on gender, temperament, and culture. She was also a tireless public intellectual, writing a column for Redbook magazine for many years and testifying before Congress on issues from nuclear weapons to environmental policy. She was married three times, all to fellow anthropologists, and her personal life was characterised by the same willingness to challenge convention that marked her intellectual work. She died in 1978.
"Never doubt that a small group of thoughtful, committed citizens can change the world; indeed, it is the only thing that ever has."
Eduardo Mondlane 1920-1969 · Mozambique (Portuguese East Africa)
Eduardo Chivambo Mondlane was a Mozambican anthropologist and revolutionary who founded FRELIMO, the movement that led Mozambique's independence struggle against Portugal. He was born in 1920 in N'wajahani, in the Gaza province of southern Mozambique, then a Portuguese colony. He was the fourth of sixteen sons of a Tsonga chief. The colonial school system was almost only for Europeans, but Mondlane gained entry through Swiss Presbyterian mission schools. He worked as a shepherd as a boy. Education in his country was almost impossible; he had to leave to get any. His academic journey was extraordinary. He studied in South Africa at Witwatersrand University, but was expelled in 1949 for opposing the new apartheid regime. He went briefly to Lisbon, then to Oberlin College in Ohio in 1951, then to Northwestern University in Illinois, where he earned a PhD in sociology in 1960. He worked at the United Nations from 1957, then taught anthropology at Syracuse University in the early 1960s. He married Janet Johnson, a white American woman from Indiana. In 1962 he left academic life. He went to Dar es Salaam in Tanzania to help unite three Mozambican exile groups into a single movement. The result was FRELIMO, the Front for the Liberation of Mozambique. He became its first president. Under his leadership FRELIMO began the armed struggle against Portuguese rule in 1964. He wrote his book The Struggle for Mozambique while leading the war. On 3 February 1969, in Dar es Salaam, he opened a parcel addressed to him. It contained a bomb. He was killed instantly. The Portuguese secret police, PIDE, is widely believed to have been responsible. He was 48. Mozambique gained independence six years later, in 1975.
