Well, I guess the operative question is: what became of the
New Woman? Did she simply morph into a Newer Woman?

No, not exactly. Two world wars got in the way. And, by the end of the second one, patriarchal society reasserted itself once again. The upshot is (in as few words as possible), after the disastrous effects of toxic-masculinity-in-action (i.e., war and genocide) depleted the world's population by
millions (upon millions) of humans; the world's "little ladies" were obligated to return to the confines of the home, and dedicate their lives to what nature (and the state) intended: motherhood. In reality, the war machine needed new blood (literally) and more human fodder, the bloated corporate sector needed fresh regiments of gullible consumers, and the government needed its tax revenue which, in the form of new taxpayers (requiring new Social Security numbers) it was a patriotic citizen's "duty" to provide. Women were expected to push more and more babies out of their wombs (and purchase the latest soap-powder) while men were obliged to finance the whole deal (or die trying).*
Needless to say, the New Woman movement lost much of its momentum during the post-war years of the mid-1900s. But, then, in (almost) Karmic retaliation,
the Baby Boomer generation was spawned. And, the Baby Boomers, in turn, beget the 60s... a time when pretty much all the best-laid plans of white mice and white men went straight to hell. Well, at least, for a decade or two. It was as if, suddenly, all the King's horses, vassals and concubines no longer gave a hoot about putting Humpty Dumpty back together again, but, instead, decided to make an omelet (with his remains) which all might share... regardless of race, religion, nationality, gene-pools or gender. And, it was from this mighty upheaval that second-wave feminism was born.

This is not to say that all females of artistic persuasion were driven underground during the post-war period. No, the feminist spirit was kept alive by a number of female artists who had been born later in the time-frame, at the very end of the 19th century. Many of these women also gravitated to Paris, and it is their artwork which illuminates this section.
First in line: the 1939 painting,
Rhythm Colour no. 1076, by Ukrainian-born French artist
Sonia Delaunay (1885-1979) - above,
inset left - who co-founded Orphism (a form of cubism) with her more celebrated husband, French artist, Robert Delauney. Wiki tells us that
"she was the first living female artist to have a retrospective exhibition at the Louvre in 1964."

As it was, she was one of four female artists initially considered Cubists and one of three who survived the wars to witness the next wave of feminism in bloom. The one Cubist who tragically missed the new resurgence was Spanish artist
María Blanchard (1881-1939), whose 1916 painting
Composición cubista appears next (above,
inset right). Above,
inset left, is
Composition cubiste by Polish painter Alice (or Alicja) Halicka (1894-1975), while (directly)
inset right is a portrait of artist Diego Rivera by Russian-born (Cubist-turned-pointillist)
Marie Bronislava Vorobyeva-Stebelska (1892-1984)... also known as
Marevna. Of note: in 1919 Marevna gave birth to a daughter fathered by Rivera who, as we know, later married (Patron Saint)
Frida Kahlo. More of Marevna's work can be found
here.
Speaking of Patron Saints, there was another, German-American visionary and Transcendentalist artist,
Agnes Pelton (1881–1961), who can be counted among the women who appear here. Her Patron Saint article is
here. Her 1939 painting below,
Sea Change, was sourced from a Whitney Museum of American art page. As it was, Pelton was one of two female artists asked to join the
Transcendentalist Painting Goup, the other was
Florence Miller Pierce (1918-2007). You can find her work
here.

And, then, in the latter years of the 19th century, something marvelous occurred... and the 19th century dealt us one of its last cards: an American pioneer, an artist who, living for almost 100 years (1887-1986), would take us into the 20th century and beyond, finally setting the record straight for all female artists while inspiring countless others (myself included). That is, yes, women could be innovators in the art world, and yes, women could be masters at their craft, and, most definitely, women could contribute to the human footprint sans the obligatory "baby-bump." Her name was
Georgia Totto O'Keeffe and she broke every rule in the book, besting the men at their own game without batting an eyelash. She is, in fact, Trans-D's missing Patron Saint #12... but, if I never get to her, know that I meant to. Of all her prolific work she is best known for her massive flower paintings (
Inset left is
Red Canna (1924); another painting is below the jump); organic marvels of which she said:
“When you take a flower in your hand and really look at it, it's your world for the moment. I want to give that world to someone else.”
