Maude Squire was born January 30, 1873 in Cincinnati.  Her parents encouraged her artistic training, though both had died by the time she was a young woman.  At the age of 21, she enrolled in the Cincinnati Art Academy and studied under Lewis Henry Meakin and Frank Duveneck.  At the academy she met fellow student Ethel Mars, with whom she would live and travel for the rest of her life.

Squire began her career while still a student, traveling to New York to meet with publishers and exhibiting her work.  By 1900 she and Mars were living in New York City, traveling to Europe, and collaborating on illustrating children's books.  By 1906 they had settled in Paris together.  Within a few months of their residence in the city, Squire and Mars had adopted the radical (for the times) use of flamboyant hair coloring and garish makeup.  Certainly, the young women reveled in the social freedoms that Paris offered.

However outrageous, it was Squire's artistic accomplishments that garnered repeated invitations to Gertrude Stein's salon at 27 rue de Fleurus, where she (and Mars) met such luminaries as Picasso and Matisse.  The connections Squire made at the home of Stein and her partner Alice B. Toklas contributed significantly to the development of her career. 

In the 1920s, Squire returned to Europe, eventually settling in Vence on the French Riviera.  There she was active in an artists' community that included Marsden Hartley and Reginald Marsh.  She continued to collaborate with Mars on children's book illustration as well as making her paintings.  Squire concentrated on large-scale watercolors of outdoor public scenes, and continued working until about 1930. 

In her lifetime, she exhibited her work at the Art Institute of Chicago, the Panama Pacific Exhibition of 1915, Pennsylvania Academy, Provincetown Art Association, and the Society of Independent Artists - of which she was a member. 

She died in 1955 in Vence, France at the age of 82.
