François-Joseph Servois (1768-1847) lived during times of great upheaval. (See [Petrilli 2010] for more biographical information on Servois.) Politically, the French Revolution broke out when he was a young priest of only twenty-one years. As a result of the new social order and the many upheavals and wars that followed the revolution, he chose to become a soldier. Later in his military career, he became a professor of mathematics at various military academies.

Mathematically, these were also revolutionary times. By the early 19th century, the differential and integral calculus was more than a century old, but mathematicians knew that there were still significant problems with the foundations of the subject. Augustin Louis Cauchy (1789-1857) devised a rigorous, limit-based analysis in the 1820s, which eventually settled the foundational question of the calculus. However, during Servois' period as an active researcher, there were at least three competing foundational notions for the calculus and no clear indication as to which of them would eventually give rise to a satisfactory account.
