Louise Cayrol was born in 1847 in Foix, in the département of Ariège in southern France. Her parents were Antoine Cayrol and Jeanne Cayrol (nee Bonnafous), and her sister was named Anne.^[5]

In 1870, in Paris, she married Edouard Sarazin, a patents lawyer from Liège, Belgium, and they had three children, including a daughter Jeanne in 1878 and a son Auguste Henri born in Asnières-sur-Seine in 1880.^[5]

Edouard Sarazin was an entrepreneurial industrialist, patents lawyer and pioneer of automotive engineering, who was in a mix of automotive partnerships and agencies with Émile Levassor, John Cockerill, Deutz AG, and Gottlieb Daimler. In 1884 Sarazin, the representative of the German company Gasmotorenfabrik Otto & Langen (Deutz AG) acquired the licence to build Deutz engines in France, which he duly contracted to Perin, Panhard & Cie in Paris. Around 1886/7 he similarly acquired licences to build Daimler engines in France, and to conform to French Patent Law he commissioned Panhard & Levassor to produce "some" Daimler engines in Paris.^[1]: p.11 His untimely death in 1887 left his widow to develop the business relationships and complete the partnership with Daimler. On February 5, 1889, she signed a contract in which Daimler received 12% of the sales price of all engines produced in France and she received 20% from Panhard & Levassor.^{[2][5][3][1]: p.14}

Death-bed wish edit

Sarazin's deathbed words to his wife were:^[4] "In your own interests, and for the good of our children, I recommend that you maintain the business connection with Daimler. His invention is entirely trustworthy, and it will have a future, the magnitude of which we cannot begin to imagine today."

He also asked that she maintain the relationship with Levassor and Panhard.^[4] To wit ...

In May 1890 Mme. Louise Sarazin married Emile Levassor.^[1]: p.16

During the 1896 Paris–Marseille–Paris race, he swerved to avoid a dog, crashed and was seriously injured. He never fully recovered and died in Paris the following year.^[3]
