Degas was born in Paris, France, into a moderately wealthy family. He was the oldest of five children of Célestine Musson De Gas, a Creole from New Orleans, Louisiana, and Augustin De Gas, a banker. His maternal grandfather Germain Musson, was born in Port-au-Prince, Haiti of French descent and had settled in New Orleans in 1810.Degas (he adopted this less grandiose spelling of his family name when he became an adult) began his schooling at age eleven, enrolling in the Lycée Louis-le-Grand. His mother died when he was thirteen, and his father and grandfather became the main influences on him for the remainder of his youth.

Degas began to paint early in life. By the time he graduated from the Lycée with a baccalauréat in literature in 1853, at age 18, he had turned a room in his home into an artist's studio. Upon graduating, he registered as a copyist in The Louvre Museum, but his father expected him to go to law school. Degas duly enrolled at the Faculty of Law of the University of Paris in November 1853, but applied little effort to his studies. In 1855 he met Jean-Auguste-Dominique Ingres, whom Degas revered and whose advice he never forgot: "Draw lines, young man, and still more lines, both from life and from memory, and you will become a good artist."

Degas's paintings, pastels, drawings, and sculptures are on prominent display in many museums, and have been the subject of many museum exhibitions and retrospectives. Recent exhibitions include Degas: Drawings and Sketchbooks (The Morgan Library, 2010); Picasso Looks at Degas (Museu Picasso de Barcelona, 2010); Degas and the Nude (Museum of Fine Arts, Boston, 2011); Degas' Method (Ny Carlsberg Glyptotek, 2013); and Degas's Little Dancer (National Gallery of Art, Washington D.C., 2014).
