Little Dancer of Fourteen Years
The "Little Dancer" wax sculpture we see today is a reworked version of the original sculpture that was shown in 1881. After seeing the wax sculpture in Degas’ living quarters in April 1903, the New York collector Louisine Havemeyer expressed interest in buying the wax. After proposing a bronze or cast wax of the sculpture, which Mrs. Havemeyer refused, Degas took his wax figure upstairs to his working studio and told Vollard he was reworking the sculpture for Havemeyer for 40,000 francs. Degas never sold the sculpture to Mrs. Havemeyer. After Degas died, it was found in a corner of his studio. Paul Lefond, Degas’ biographer, described the "Little Dancer" wax after Degas’ death as "nothing but a ruin;" and Mary Cassatt telegraphed Mrs. Havemeyer "Statue Bad Condition." However, the wax sculpture we know today is not a ruin. It is Degas' reworked second version of his wax figure. At some point before Degas extensively reworked his sculpture, he allowed a plaster to be cast from the wax figure. This recently re-discovered plaster records the "Little Dancer"’s original pose, bodice, and hairdo. The plaster is now in a private collection in the United States.
Edgar Degas
Both regarded themselves as figure painters, and the art historian George Shackelford suggests they were influenced by the art critic Louis Edmond Duranty's appeal in his pamphlet "The New Painting" for a revitalization in figure painting: "Let us take leave of the stylized human body, which is treated like a vase. What we need is the characteristic modern person in his clothes, in the midst of his social surroundings, at home or out in the street." 
After Cassatt's parents and sister Lydia joined Cassatt in Paris in 1877, Degas, Cassatt, and Lydia were often to be seen at the Louvre studying artworks together. Degas produced two prints, notable for their technical innovation, depicting Cassatt at the Louvre looking at artworks while Lydia reads a guidebook. These were destined for a prints journal planned by Degas (together with Camille Pissarro and others), which never came to fruition. Cassatt frequently posed for Degas, notably for his millinery series trying on hats.
