Austen's works critique the novels of sensibility of the second half of the 18th century and are part of the transition to 19th-century realism.[4][C] Her plots, though fundamentally comic,[5] highlight the dependence of women on marriage to secure social standing and economic security.[6] Her works, though usually popular, were first published anonymously and brought her little personal fame and only a few positive reviews during her lifetime, but the publication in 1869 of her nephew's A Memoir of Jane Austen introduced her to a wider public, and by the 1940s she had become widely accepted in academia as a great English writer. The second half of the 20th century saw a proliferation of Austen scholarship and the emergence of a Janeite fan culture.
