Prud'hon painted several portraits of Mlle. Mayer, the best-known being now in the Louvre. It represents an engaging personality, in which vivacity and sensibility are distinctly indicated.

Mlle. Mayer had made her début at the Salon of 1896 with a portrait of "Citizeness Mayer," painted by herself, and showing a sketch for the portrait of her mother; also a picture of a "Young Scholar with a Portfolio Under His Arm," and a miniature. From this time her work was seen at each year's salon.

Her pictures in 1810 were the "Happy Mother" and the "Unhappy Mother," which are now in the Louvre; the contrast between the joyousness of the mother with her child and the anguish of the mother who has lost her child is portrayed with great tenderness. The "Dream of Happiness," also in the Louvre, represents a young couple in a boat with their child; the boat is guided down the stream of life by Love and Fortune. This is one of her best pictures. It is full of poetic feeling, and the flesh tints are unusually natural. The work of this artist is characterized by delicacy of touch and freshness of color while pervaded by a peculiar grace and charm. Her drawing is good, but the composition is less satisfactory.

It is well known that Prud'hon and his pupil painted many pictures in collaboration. This has led to an under-valuation of her ability, and both the inferior works of Prud'hon and bad imitations of him have been attributed to her. M. Guenllette writes that when Mlle. Mayer studied under Greuze she painted in his manner, and he inclines to the opinion that some pictures attributed to Greuze were the work of his pupil. In the same way she imitated Prud'hon, and this critic thinks it by no means certain that the master finished her work, as has been alleged.

In the Museum at Nancy are Mlle. Mayer's portraits of Mme. and Mlle. Voiant; in the Museum of Dijon is an ideal head by her, and in the Bordeaux Gallery is her picture, called "Confidence." "Innocence Prefers Love to Riches" and the "Torch of Venus" are well-known works by Mlle. Mayer.

Mesdag-van Houten, S. Gold medal at Amsterdam, 1884; bronze medal, Paris Exposition, 1889. Born at Groningen, 1834. In 1856 she married Mesdag, who, rather late in life decided to follow the career of a painter. His wife, not wishing to be separated from him in any sense, resolved on the same profession, and about 1870 they began their study. Mme. Mesdag acquired her technique with difficulty, and her success was achieved only as the result of great perseverance and continual labor. The artists of Oosterbeck and Brussels, who were her associates, materially aided her by their encouragement. She began the study of drawing at the age of thirty, and her first attempt in oils was made seven years later. Beginning with single twigs and working over them patiently she at length painted whole trees, and later animals. She came to know the peculiarities of nearly all native trees.

She built a studio in the woods of Scheveningen, and there developed her characteristics—close observation and careful reproduction of details.

In the summer of 1872 M. and Mme. Mesdag went to Friesland and Drenthe, where they made numerous sketches of the heath, sheep, farmhouses, and the people in their quaint costumes. One of Mme. Mesdag's pictures, afterward exhibited at Berlin, is thus described: "On this canvas we see the moon, just as she has broken through a gray cloud, spreading her silvery sheen over the sleepy land; in the centre we are given a sheep-fold, at the door of which a flock of sheep are jostling and pushing each other, all eager to enter their place of rest. The wave-like movement of these animals is particularly graceful and cleverly done. A little shepherdess is guiding them, as anxious to get them in as they are to enter, for this means the end of her day's work. Her worn-out blue petticoat is lighted up by a moonbeam; in her hand she appears to have a hoe. It is a most harmonious picture; every line is in accord with its neighbor."

While residing in Brussels these two artists began to collect works of art for what is now known as the Mesdag Museum. In 1887 a wing was added to their house to accommodate their increasing treasures, which include especially good examples of modern French painting, pottery, tapestry, etc.
