Mary Stevenson Cassatt (May 22, 1844 – June 14, 1926) was an American painter and printmaker. She lived much of her adult life in France, where she first befriended Edgar Degas and later exhibited among the Impressionists. Cassatt often created images of the social and private lives of women, with particular emphasis on the intimate bonds between mothers and children.

Cassatt was born in Allegheny City, Pennsylvania, which is now part of Pittsburgh. She was born into favorable circumstances: her father, Robert Simpson Cassat (later Cassatt), was a successful stockbroker and land speculator, and her mother, Katherine Kelso Johnston, came from a banking family. The ancestral name had been Cossart. Cassatt was a distant cousin of artist Robert Henri. Cassatt was one of seven children, of which two died in infancy. Her family moved eastward, first to Lancaster, Pennsylvania, then to the Philadelphia area, where she began schooling at age 6. Cassatt grew up in an environment that viewed travel as integral to education; she spent 5 years in Europe and visited many of the capitals, including London, Paris, and Berlin. While abroad she learned German and French and had her first lessons in drawing and music. Her first exposure to French artists Ingres, Delacroix, Corot, and Courbet was likely at the Paris World’s Fair of 1855. Also exhibited at the exhibition were Degas and Pissarro, both of whom would be her future colleagues and mentors.

Even though her family objected to her becoming a professional artist, Cassatt began studying painting at the Pennsylvania Academy of the Fine Arts in Philadelphia, Pennsylvania, at the early age of 15. Part of her parents' concern may have been Cassatt’s exposure to feminist ideas and the bohemian behavior of some of the male students. Although about 20 percent of the students were female, most viewed art as a socially valuable skill; few of them were determined, as Cassatt was, to make art their career. She continued her studies during the years of the American Civil War. Among her fellow students was Thomas Eakins, later the controversial director of the Academy. Impatient with the slow pace of instruction and the patronizing attitude of the male students and teachers, she decided to study the old masters on her own. She later said, “There was no teaching” at the Academy. Female students could not use live models (until somewhat later) and the principal training was primarily drawing from casts.

Cassatt decided to end her studies (at that time, no degree was granted). After overcoming her father’s objections she moved to Paris in 1866, with her mother and family friends acting as chaperones. Since women could not yet attend the École des Beaux-Arts, she applied to study privately with masters from the school and was accepted to study with Jean-Léon Gérôme, a highly regarded teacher known for his hyper-realistic technique and his depiction of exotic subjects. A few months later Gérôme would also accept Eakins as a student. Cassatt augmented her artistic training with daily copying in the Louvre (she obtained the required permit, which was necessary to control the “copyists”, usually low-paid women, who daily filled the museum to paint copies for sale). The museum also served as a social meeting place for Frenchmen and American female students, who like Cassatt, were not allowed to attend cafes where the avant-garde socialized. In this manner, fellow artist and friend Elizabeth Jane Gardner met and married famed academic painter William-Adolphe Bouguereau.

Toward the end of 1866, she joined a painting class taught by Charles Chaplin, a noted genre artist. In 1868, Cassatt also studied with artist Thomas Couture, whose subjects were mostly romantic and urban. On trips to the countryside, the students drew from life, particularly the peasants going about their daily activities. In 1868 one of her paintings, A Mandoline Player, was accepted for the first time by the selection jury for the Paris Salon. This work is in the Romantic style of Corot and Couture, and is one of only two paintings from the first decade of her career that can be documented today. The French art scene was in a process of change, as radical artists such as Courbet and Manet tried to break away from accepted Academic tradition and the Impressionists were in their formative years. Cassatt’s friend Eliza Haldeman wrote home that artists “are leaving the Academy style and each seeking a new way, consequently just now everything is Chaos”. Cassatt, on the other hand, would continue to work in the traditional manner, submitting works to the Salon for over ten years, with increasing frustration.

Returning to the United States in the late summer of 1870 — as the Franco-Prussian War was starting — Cassatt lived with her family in Altoona. Her father continued to resist her chosen vocation, and paid for her basic needs, but not her art supplies. She placed two of her paintings in a New York gallery and found many admirers but no purchasers. She was also dismayed at the lack of paintings to study while staying at her summer residence. Cassatt even considered giving up art, as she was determined to make an independent living. She wrote in a letter of July, 1871, "I have given up my studio & torn up my father's portrait, & have not touched a brush for six weeks nor ever will again until I see some prospect of getting back to Europe. I am very anxious to go out west next fall & get some employment, but I have not yet decided where." She traveled to Chicago to try her luck but lost some of her early paintings in the Great Chicago Fire of 1871. Shortly afterward, her work attracted the attention of the Archbishop of Pittsburgh, who commissioned her to paint two copies of paintings by Correggio in Parma, Italy, advancing her enough money to cover her travel expenses and part of her stay. In her excitement she wrote, “O how wild I am to get to work, my fingers farely itch & my eyes water to see a fine picture again”. With Emily Sartain, a fellow artist from a well-regarded artistic family from Philadelphia, Cassatt set out for Europe again.

Within months of her return to Europe in the autumn of 1871, Cassatt’s prospects had brightened. Her painting Two Women Throwing Flowers During Carnival was well received in the Salon of 1872, and was purchased. She attracted much favorable notice in Parma and was supported and encouraged by the art community there: “All Parma is talking of Miss Cassatt and her picture, and everyone is anxious to know her”.

After completing her commission for the archbishop, Cassatt traveled to Madrid and Seville, where she painted a group of paintings of Spanish subjects, including Spanish Dancer Wearing a Lace Mantilla (1873, in the National Museum of American Art, Smithsonian Institution). In 1874, she made the decision to take up residence in France. She was joined by her sister Lydia who shared an apartment with her. Cassatt continued to express criticism of the politics of the Salon and the conventional taste that prevailed there. She was blunt in her comments, as reported by Sartain, who wrote: “she is entirely too slashing, snubs all modern art, disdains the Salon pictures of Cabanel, Bonnat, all the names we are used to revere”. Cassatt saw that works by female artists were often dismissed with contempt unless the artist had a friend or protector on the jury, and she would not flirt with jurors to curry favor. Her cynicism grew when one of the two pictures she submitted in 1875 was refused by the jury, only to be accepted the following year after she darkened the background. She had quarrels with Sartain, who thought Cassatt too outspoken and self-centered, and eventually they parted. Out of her distress and self-criticism, Cassatt decided that she needed to move away from genre paintings and onto more fashionable subjects, in order to attract portrait commissions from American socialites abroad, but that attempt bore little fruit at first.

In 1877, both her entries were rejected, and for the first time in seven years she had no works in the Salon. At this low point in her career she was invited by Edgar Degas to show her works with the Impressionists, a group that had begun their own series of independent exhibitions in 1874 with much attendant notoriety. The Impressionists (also known as the “Independents” or “Intransigents”) had no formal manifesto and varied considerably in subject matter and technique. They tended to prefer open air painting and the application of vibrant color in separate strokes with little pre-mixing, which allows the eye to merge the results in an “impressionistic” manner. The Impressionists had been receiving the wrath of the critics for several years. Henry Bacon, a friend of the Cassatts, thought that the Impressionists were so radical that they were “afflicted with some hitherto unknown disease of the eye”. They already had one female member, artist Berthe Morisot, who became Cassatt’s friend and colleague.

Cassatt admired Degas, whose pastels had made a powerful impression on her when she encountered them in an art dealer's window in 1875. "I used to go and flatten my nose against that window and absorb all I could of his art," she later recalled. "It changed my life. I saw art then as I wanted to see it." She accepted Degas' invitation with enthusiasm, and began preparing paintings for the next Impressionist show, planned for 1878, which (after a postponement because of the World’s Fair) took place on April 10, 1879. She felt comfortable with the Impressionists and joined their cause enthusiastically, declaring: “we are carrying on a despairing fight & need all our forces”. Unable to attend cafes with them without attracting unfavorable attention, she met with them privately and at exhibitions. She now hoped for commercial success selling paintings to the sophisticated Parisians who preferred the avant-garde. Her style had gained a new spontaneity during the intervening two years. Previously a studio-bound artist, she had adopted the practice of carrying a sketchbook with her while out-of-doors or at the theater, and recording the scenes she saw.

In 1877, Cassatt was joined in Paris by her father and mother, who returned with her sister Lydia. Mary valued their companionship, as neither she nor Lydia had married. Mary had decided early in life that marriage would be incompatible with her career. Lydia, who was frequently painted by her sister, suffered from recurrent bouts of illness, and her death in 1882 left Cassatt temporarily unable to work. Cassatt’s father insisted that her studio and supplies be covered by her sales, which were still meager. Afraid of having to paint “potboilers” to make ends meet, Cassatt applied herself to produce some quality paintings for the next Impressionist exhibition. Three of her most accomplished works from 1878 were Portrait of the Artist (self-portrait), Little Girl in a Blue Armchair, and Reading Le Figaro (portrait of her mother).

Degas had considerable influence on Cassatt. She became extremely proficient in the use of pastels, eventually creating many of her most important works in this medium. Degas also introduced her to etching, of which he was a recognized master. The two worked side-by-side for awhile, and her draftsmanship gained considerable strength under his tutelage. He depicted her in a series of etchings recording their trips to the Louvre. She had strong feelings for him but learned not to expect too much from his fickle and temperamental nature. The sophisticated and well-dressed Degas, then forty-five, was a welcome dinner guest at the Cassatt residence.

The Impressionist exhibit of 1879 was the most successful to date, despite the absence of Renoir, Sisley, Manet and Cézanne, who were attempting once again to gain recognition at the Salon. Through the efforts of Gustave Caillebotte, who organized and underwrote the show, the group made a profit and sold many works, although the criticism continued as harsh as ever. The Revue des Deux Mondes wrote, “M. Degas and Mlle. Cassatt are, nevertheless, the only artists who distinguish themselves... and who offer some attraction and some excuse in the pretentious show of window dressing and infantile daubing”. Cassatt displayed eleven works, including La Loge. Although critics claimed that Cassatt’s colors were too bright and that her portraits were too accurate to be flattering to the subjects, her work was not savaged as was Monet's, whose circumstances were the most desperate of all the Impressionists at that time. She used her share of the profits to purchase a work by Degas and one by Monet. She exhibited in the Impressionist Exhibitions that followed in 1880 and 1881, and she remained an active member of the Impressionist circle until 1886.

In 1886, Cassatt provided two paintings for the first Impressionist exhibition in the United States, organized by art dealer Paul Durand-Ruel. Her friend Louisine Elder married Harry Havemeyer in 1883, and with Cassatt as advisor, the couple began collecting the Impressionists on a grand scale. Much of their vast collection is now in the Metropolitan Museum of Art in New York City. She also made several portraits of family members during that period, of which Portrait of Alexander Cassatt and His Son Robert Kelso (1885) is one of her best regarded. Cassatt’s style then evolved, and she moved away from Impressionism to a simpler, more straightforward approach. She began to exhibit her works in New York galleries as well. After 1886, Cassatt no longer identified herself with any art movement and experimented with a variety of techniques.

Cassatt's popular reputation is based on an extensive series of rigorously drawn, tenderly observed, yet largely unsentimental paintings and prints on the theme of the mother and child. The earliest dated work on this subject is the drypoint Gardner Held by His Mother (an impression inscribed "Jan/88" is in the New York Public Library), although she had painted a few earlier works on the theme. Some of these works depict her own relatives, friends, or clients, although in her later years she generally used professional models in compositions that are often reminiscent of Italian Renaissance depictions of the Madonna and Child. After 1900, she concentrated almost exclusively on mother-and-child subjects.

The 1890s were Cassatt's busiest and most creative time. She had matured considerably and became more diplomatic and less blunt in her opinions. She also became a role model for young American artists who sought her advice. Among them was Lucy A. Bacon, whom Cassatt introduced to Camille Pissarro. Though the Impressionist group disbanded, Cassatt still had contact with some of the members, including Renoir, Monet, and Pissarro.

In 1891, she exhibited a series of highly original colored drypoint and aquatint prints, including Woman Bathing and The Coiffure, inspired by the Japanese masters shown in Paris the year before. Cassatt was attracted to the simplicity and clarity of Japanese design, and the skillful use of blocks of color. In her interpretation, she used primarily light, delicate pastel colors and avoided black (a “forbidden” color among the Impressionists). A. Breeskin, of the Smithsonian Institution, notes that these colored prints, “now stand as her most original contribution... adding a new chapter to the history of graphic arts... technically, as color prints, they have never been surpassed”.

Also in 1891, Chicago businesswoman Bertha Palmer approached Cassatt to paint a 54' × 12' mural about "Modern Woman" for the Women's Building for the World's Columbian Exposition to be held in 1893. Cassatt completed the project over the next two years while living in France with her mother. The mural was designed as a triptych. The central theme was titled Young Women Plucking the Fruits of Knowledge or Science. The left panel was Young Girls Pursuing Fame and the right panel Arts, Music, Dancing. The mural displays a community of women apart from their relation to men, as accomplished persons in their own right. Palmer considered Cassatt to be an American treasure and could think of no one better to paint a mural at an exposition that was to do so much to focus the world's attention on the status of women. Unfortunately the mural was lost when the building was torn down after the exhibit. Cassatt made several studies and paintings on themes similar to those in the mural around that time, however, so it is possible to see her development of those ideas and images. Cassatt also exhibited other paintings in the Exposition.

As the new century arrived, Cassatt served as an advisor to several major art collectors and stipulated that they eventually donate their purchases to American art museums. In recognition of her contributions to the arts, France awarded her the Légion d'honneur in 1904. Although instrumental in advising American collectors, recognition of her art came more slowly in the United States. Even among her family members back in America, she received little recognition and was totally overshadowed by her famous brother.

Mary Cassatt's brother, Alexander Cassatt, (president of the Pennsylvania Railroad from 1899 until his death) died in 1906. She was shaken, as they had been close, but she continued to be very productive in the years leading up to 1910. An increasing sentimentality is apparent in her work of the 1900s; her work was popular with the public and the critics, but she was no longer breaking new ground, and her Impressionist colleagues who once provided stimulation and criticism were dying off. She was hostile to such new developments in art as post-Impressionism, Fauvism and Cubism.

A trip to Egypt in 1910 impressed Cassatt with the beauty of its ancient art, but was followed by a crisis of creativity; not only had the trip exhausted her, but she declared herself "crushed by the strength of this Art", saying, "I fought against it but it conquered, it is surely the greatest Art the past has left us ... how are my feeble hands to ever paint the effect on me." Diagnosed with diabetes, rheumatism, neuralgia, and cataracts in 1911, she did not slow down, but after 1914 she was forced to stop painting as she became almost blind. Nonetheless, she took up the cause of women's suffrage, and in 1915, she showed eighteen works in an exhibition supporting the movement.

She died on June 14, 1926 at Château de Beaufresne, near Paris, and was buried in the family vault at Le Mesnil-Théribus, France.
