(For a second, like many, I thought it said "Nancy Mitford.")

Oddly, there's only one obit so far.

Nancy Milford, the biographer of women who helped light up the Jazz Age — Zelda Fitzgerald, the “original flapper” and wife and literary muse of F. Scott Fitzgerald, and the poet Edna St. Vincent Millay — died on Tuesday at her home in Manhattan. She was 84.

Her son, Matthew Milford, said the cause had not been determined.

An indefatigable researcher, Ms. Milford brought the chaotic, troubled Zelda Fitzgerald and her world to vivid life in “Zelda” (1970) through letters, albums, scrapbooks, interviews with her friends and her husband’s as well as reports by psychiatrists who treated Zelda for schizophrenia. Her mental health was declining by the late 1920s and led to institutionalizations in the 1930s and ’40s.

“She haunts our idea of what it is like to be this spirited girl caught in a web of destruction, which ends up being romanticized,” Ms.. Milford told Interview magazine in 2011.

During one stay at a clinic in Baltimore in 1932, the Alabama-born Zelda quickly wrote “Save Me the Waltz” (1932), a semi-autobiographical novel about a Southern belle, Alabama Beggs; her husband, a painter; and her attempt to become a ballet dancer. In “Zelda,” Ms. Milford called the novel a “good deal more than the curio of a deranged sensibility working over the grievances of a life with Scott Fitzgerald, or of a life shattered by mental illness.”

....After the publication of “Zelda,” it took Ms. Milford 31 years to complete “Savage Beauty: The Life of Edna St. Vincent Millay,” about the poet whose immense popularity in the 1920s and ’30s — she won the Pulitzer Prize in poetry in 1923 — faded quickly afterward...
