Seurat was born on 2 December 1859 in Paris into a relatively wealthy family. His father, Chrysostome-Antoine Seurat, was a legal official in La Villette and his mother, Ernestine Faivre, a quiet and unassuming woman who came from a prosperous middle-class Parisian family. While his father was a solitary and unexpressive person who only saw his family once a week, it was his mother who gave some warmth and continuity to his childhood.
During his schooldays, Seurat was introduced to painting by an uncle on his mother's side, the textile dealer Paul Haumonté-Faivre, also an amateur painter. In 1875 he started to attend a drawing class taught by the sculptor Justin Lequien at a night school in the city and in 1878, he was admitted to the École des Beaux-Arts. Here he joined the painting class of Henri Lehmann, a pupil of Jean Auguste Dominique Ingres. The students of the class studied and copied the old masters in the Louvre and the young Seurat was strongly influenced by Rembrandt and Francisco de Goya.
As a young man Seurat was tall and handsome with soulful eyes and a quiet, gentle voice. He was always quite reserved and dignified in dress and manner, so much so, that one friend described him as looking like a floor-walker in a department store, while Edgar Degas nicknamed him "the notary". He was serious and intense and preferred to spend his money on books rather than on food or drink. Like his father Chrysostome-Antoine, however, his most outstanding characteristic was his secretiveness.
Despite many of the qualities of the perfect student, Seurat did not particularly excel at school or at the Ecole des Beaux-Arts, but thanks to a regular allowance, he never had any need to sell his work for a living, nor to produce work that was saleable.
In 1879, Seurat was drafted for military service and sent to the great military port of Brest on the western coast of Brittany. Here he fitted in easily to barracks discipline and used his spare time to begin sketching figures and ships.
On returning to Paris in 1880, the young artist initially shared a cramped studio on the Left Bank with two student friends Aman-Jean and Ernest Laurent. He later moved to a studio of his own, closer to his parent's home on the Right Bank, where he painted his most important works up till 1886. For the first two years, he devoted himself to mastering the art of black and white drawing. Then, in the year 1883, most of his time was spent on a huge canvas, "Bathing at Asnieres", which was his first major painting and also the first of the six large canvasses that would constitute the bulk of his life's work.
