Edna Wolff (Henner) Maschgan
The above painting,
by Edna Maschgan (1907-2001)
currently at Treadway Gallery,
reads "Palette and Chisel, Bitterly Award"
So, she must have been
among the first women members
(update: I've just spoken with Joe Vangsness,
who knew her when she became a member in the 80's,
so no, she was not among the first women to join.
As Joe remembers,
she was a short, serious artist
who called herself "Eddie",
and was married to Dr. Erich Maschgan,
the veterinarian at the Lincoln Park Zoo)
The gallery also notes
that she studied in Mexico
with Diego Rivera
in the 1920's
I'll have to scour the P&C archives
for any mention of her
She certainly did some interesting work,
quite different from
anyone else I've yet seen here.
