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.
