Bourgeois delivered Christine de France (Christine Marie), later Duchess of Savoy, on 10 February 1606.
On 10 February 1606, Louise Bourgeois oversaw the birth of Christine de France, also known as Christine Marie, the third child of Henry IV and Marie de Medici. Christine would go on to become Duchess of Savoy through marriage, further extending the political reach of the French crown across Europe.
This delivery continued Bourgeois's unbroken record of successful royal births, a remarkable achievement given the significant dangers of childbirth in the early seventeenth century, when infection, hemorrhage, and malpresentation claimed the lives of mothers and infants across all strata of society, including nobility.
Her sustained presence at the French court across multiple pregnancies illustrates the depth of trust placed in her by Marie de Medici personally, who reportedly insisted on Bourgeois's attendance for each of her children rather than relying on court physicians alone. This personal loyalty from the queen was a critical factor in protecting Bourgeois's position amid professional rivalries with male surgeons who increasingly sought greater involvement in childbirth.
The birth of Christine de France represents another link in the chain of royal deliveries that Bourgeois would draw upon extensively in her later published works, providing rare documented case histories of royal obstetric care that were virtually unprecedented in print from a female practitioner's own hand.
