This chapter pulls all the strands of the book together, to contend that women were challenging the masculine public sphere in a wide variety of ingenious ways during the interwar period and that these pioneers paved the way for a wider acceptance of women as professionals. The chapter assesses some of the most important attributes and dispositions that women needed to succeed, including education, good social networks, a willingness to transgress or outrage and personal courage. The lack of a father was also a possible advantage during this period, since the absence of the key patriarchal figure from a young woman’s life could remove an enormous obstacle. This chapter ends by assessing the usefulness of biography as a method of analysis.
