Ellen Johnson Sirleaf is the first female president in Africa.

Ellen Johnson Sirleaf, the 23rd elected president of Liberia, is Africa's first female elected president. In her political and personal memoir, “This Child Will Be Great,” Sirleaf shows her determination and courage through stories about her happy childhood and unhappy marriage, and gives an inside look at a country that is working to rebuild itself.

Ellen Johnson Sirleaf was sworn in Monday as war-battered Liberia's new president, making history as Africa's first elected female head of state and pledging a "fundamental break" with the West African nation's violent past.
