Seymour Montefiore Robert Rosso de Ricci was born in 1881 in Twickenham, United Kingdom. His parents were Helen Montefiore (c. 1860-1931) and James Herman de Ricci (1847–1900). He lived with his mother in Paris after 1890, when his parents divorced. His father was a colonial judge and a lawyer.
Education and early career
Between 1890 and 1898, de Ricci attended the Lycée Janson de Sailly. He attended and subsequently received his bachelier ès lettres from École pratique des hautes études, Sorbonne in 1897. He went to Côtes-du-Nord, Brittany where he studied Roman inscriptions. He met Salomon Reinach, who would be a close friend and mentor, and Émile Guimet. He took an inventory of the inscriptions and published his first book about them in 1897. In 1901 he received his licence. He was a private scholar of epigraphy, Egyptology and bibliography.
