Hermann Karl Hesse was born on 2 July 1877 in the Black Forest town of Calw in Württemberg, German Empire.
 His grandparents served in India at a mission under the auspices of the Basel Mission, a Protestant Christian missionary society.
His grandfather Hermann Gundert compiled the current grammar in Malayalam language, compiled a Malayalam-English dictionary, and also contributed to the work in translating the Bible to Malayalam.
Hesse's mother, Marie Gundert, was born at such a mission in India in 1842.
 In describing her own childhood, she said, "A happy child I was not..." As was usual among missionaries at the time, she was left behind in Europe at the age of four when her parents returned to India.

Hesse's father, Johannes Hesse, the son of a doctor, was born in 1847 in Weissenstein, Governorate of Estonia in the Russian Empire (now Paide, Järva County, Estonia).
Johannes Hesse belonged to the Baltic German minority in the Russian-ruled Baltic region: thus his son Hermann was at birth both a citizen of the German Empire and the Russian Empire.
Hermann had five siblings, but two of them died in infancy.
In 1873, the Hesse family moved to Calw, where Johannes worked for the Calwer Verlagsverein, a publishing house specializing in theological texts and schoolbooks.
Marie's father, Hermann Gundert (also the namesake of his grandson), managed the publishing house at the time, and Johannes Hesse succeeded him in 1893.

Hesse grew up in a Swabian Pietist household, with the Pietist tendency to insulate believers into small, deeply thoughtful groups.
Furthermore, Hesse described his father's Baltic German heritage as "an important and potent fact" of his developing identity.
His father, Hesse stated, "always seemed like a very polite, very foreign, lonely, little-understood guest."
His father's tales from Estonia instilled a contrasting sense of religion in young Hermann. "[
It was] an exceedingly cheerful, and, for all its Christianity, a merry world... We wished for nothing so longingly as to be allowed to see this Estonia... where life was so paradisiacal, so colourful and happy."
Hermann Hesse's sense of estrangement from the Swabian petite bourgeoisie grew further through his relationship with his maternal grandmother Julie Gundert, née Dubois, whose French-Swiss heritage kept her from ever quite fitting in among that milieu.
