The naturalization of feminine and masculine qualities, which was used for the gendered division of occupations, intensified during the nineteenth century. The occupations of men were often based on physical strength, or the exercise of high public office and professions involving knowledge and power, whereas the occupations of women were more connected to dexterity and the fields of care and education. Transgression of the gendered occupational order has led to many professional “firsts” among women since the late nineteenth century, as well as to a few “firsts” among men in the early twenty-first century. Their history is closely connected to recognition of rights granted to women as well as progress towards professional equality, without however leading to equal pay.
