Esther Afua Ocloo
She began with a few shillings and twelve jars of marmalade, and argued poor women need credit, not charity.
The rise
Born Esther Afua Nkulenu on 18 April 1919 at Peki Dzake, she left Achimota School with a few shillings from an aunt, bought sugar, oranges and twelve jars, and sold her marmalade at a profit. Contracts to supply Achimota and the army followed; in 1942 she registered Nkulenu Industries, which still processes Ghanaian foods.
What they did
Trained in food technology in Britain, she taught thousands of Ghanaian women to cost, preserve and sell what they grew, finding that street vendors often out-earned office workers. At the 1975 UN women's conference in Mexico City she, Michaela Walsh and Ela Bhatt conceived Women's World Banking, formed in 1979; she chaired it until 1985, insisting poor women lacked credit, not charity.
The full picture
Micro-credit's record is now heavily contested: high effective interest rates and over-indebtedness among the poorest borrowers are documented worldwide, and the movement she helped institutionalise bears part of that. Nkulenu itself stayed a modest firm, which critics read as the limit of the model she championed.
Why it matters
Micro-credit is usually told as a Bangladeshi story. A Ghanaian marmalade maker was in the room when the idea was institutionalised, and she brought what the economists lacked: she had been the woman refused a loan.
