From the last decades of the nineteenth century up until the German occupation of the Netherlands, Dutch Jews experienced unprecedented opportunities for upward social mobility and integration into mainstream society. Dr Sietske van der Veen carried out the first systematic, large-scale analysis of the social mobility and integration of Dutch Jews with a higher social status. She studied the lives of over seven hundred Jews, with a focus on work, education, place of residence, religious affiliation, marriage, and association membership. Moreover, she analysed Jewish involvement in the women's movement, Jewish country house life, and Jewish migration to the Dutch East Indies in three separate case studies, showing how Dutch Jews from the upper middle and upper classes could act on particular opportunities in this period. The names and basic information of all 733 Jews in the Dutch Biography Portal included in her data set, can be found below.
