In 1959 Switzerland held a referendum on whether women should be allowed to vote in general elections.
Only men could take part in the referendum and two-thirds of them voted no.
Swiss women eventually won the right to vote in 1971.
Ruth Dreifuss campaigned for women’s rights as a 19-year-old during the 1959 referendum, and was instrumental in getting women elected to parliament in 1971.
She later became the first female president of Switzerland.
