Count Fernand de Saintignon (26 January 1846 – 2 January 1921) was a French steel maker. He was descended from an old aristocratic family, and became owner of a steel company with operations in Luxembourg and Lorraine by marriage. He was also interested in scientific subjects, and published several papers. He developed a spa around a source of pure, hot water discovered accidentally while exploring for coal deposits.
Fernand de Saintignon came from a family that had held the hereditary office of viscount-bailiff in Lorraine, was among the "Grands Chevaux de Lorraine", and during the 18th century was several times admitted to the Honors of the Court. The family owned several seigneuries, and had a regiment in its name, the Saintignon-dragoons, from 1759 to 1779. From the start of the 18th century the family had the title of count. A now-extinct branch was given the title of Baron of the Holy Roman Empire in 1746. In 1835 Fernand's grandfather, Charles-Joseph de Saintignon, a former officer, acquired the castle of Haute-Guentrange near Thionville, where Fernand was born. His parents were François de Saintignon (1808–57) and Caroline de Gourcy (1819–51).

Louise Legendre (1854–1932) was daughter of Joseph Jules Legendre and Marie Giraud.
Pierre Louis Giraud (1802–69) owned a blast furnace in Lasauvage, Luxembourg, and another in Longwy-Bas (Lower Longwy). Pierre Giraud had one child, Marguerite Mathilde Giraud, who married Jules Joseph Legendre (1830–70). Their daughter married Fernand de Saintignon. Legendre succeeded his father in law in 1869.Société Pierre Giraud was renamed the Société des Hauts-Fourneaux de Longwy et La Sauvage around this time.Legendre died in 1870 and was succeeded by Joseph Raty (1810–78), clerk-factor of the Lasauvage works, who became the proxyholder in charge of the company.When Raty died in 1878 Fernand de Saintignon took over the operation, which he would run until his death.In 1880 the company was renamed to De Saintignon et Cie.
The foundry at Lasauvage was permanently closed in 1877. However, Fernand De Saintignon had a whole village built there with a church, store and workers' housing for workers in the mines, which remained in operation until 1978.
De Saintignon's company built three modern blast furnaces in Longwy-Bas, specializing in cast iron production.In 1900 it was awarded mining concessions in the Luxembourg communes of Pétange and Differdange.In 1901 the company bought two blast furnaces in Gouraincourt.By 1913 De Saintignon et Cie had 500 workers and employees and produced 173,000 tons of cast iron annually.During World War I (1914–18) four blast furnaces were destroyed by the Germans.
