Amaranth Roslyn Ehrenhalt (January 15, 1928 – March 16, 2021) was an American painter, sculptor, and writer, who spent the majority of her career living and working in Paris, France before returning to New York City.

While attending PAFA, she simultaneously earned a bachelor's degree from the University of Pennsylvania studying French, English, Psychology, and Art History.

It was common for Beauford Delaney, the American expat artist who painted James Baldwin's portrait, to make himself completely at home at a table not his own, reaching for someone else's half-finished drink and swallowing it in one gulp... Another frequent visitor was the dark-eyed, dark-haired Yves Klein, sturdy from his intense study of judo, who would apply paint to nude women and have them lean against his canvases...there I would meet painters Pegeen Guggenheim and Ralph Rumney before dinner at Wadja around the corner or a gathering at Michel Mendes France's apartment.

Her influences include: Giotto and Cimabue, DaVinci, El Greco, Cezanne, Renoir, Matisse, Picasso, Kandinsky, Gorky, de Kooning, and Jackson Pollock.

Ehrenhalt has shown in group exhibitions alongside her contemporaries: Joan Mitchell, Sam Francis, Beauford Delaney, Shirley Jaffe, and others.

Her work is in collections around the world—from the Time, Inc. building in Chicago, to the Hirshhorn Museum in Washington, DC, to the National Foundation of Contemporary Art in Paris, France.

It is both an excellent example of New York School abstraction (lush colors, fluent brushwork, bustling composition) and an attempt at a new possibly eerie form of figuration.
