In 1927, when Irawati Karve, aged twenty-two, arrived in Berlin to do her doctoral studies at the Friedrich Wilhelm University, she was faced with a dilemma. As a woman of colour, the subject of her thesis was to prove her supervisor Dr Eugen Fischer’s theory of the superiority of the European race over people of colour, based on the measurement of their skulls. After examining 149 ‘white’ skulls from Germany and ‘non-white’ skulls from German colonies in East Africa, Irawati came to the opposite conclusion: the shape of the human skull did not prove racial superiority. Fischer’s theory was later discredited, but at the time, it took courage to present the paper to him and it nearly cost Irawati her PhD.
