François Gény (1861–1959) was a French jurist and professor of law at the University of Nancy, who introduced the notion of "free scientific research" to the interpretation of positive law.
His advocacy of judicial discretion in the interpretation of statutory law had an important influence across Europe. Gény also emphasized that judges should take into account social and economic factors when deciding cases.
François Gény was the fourth child of a numerous family of 12 children. His father, Alfred Gény, was a forest warden in Baccarat (North-East of France). His mother, Marie-Eugénie Huin, was the daughter of a scrivener. Two of his brothers became priests, and another one became a teacher in the University of Roma.
François Gény studied law in Nancy (North-East of France) from 1878 to 1887. He got his diploma and became college professor, he taught Roman law in Algiers (1888–1889). He also taught civil law and international law in the University of Dijon (1890–1900), where he met another famous law teacher, . He then taught civil law in Nancy from 1901 to 1931 and became dean of the faculty (1919–1925). He reintroduced classes of natural law named « Philosophical introduction to law study. »
In 1930, he became a member of the French Institute and received the Légion d'honneur (French highest decoration) in 1934. Nine universities conferred him the title of Doctorate Honoris Causa: Groningen (1914), Leuven (1927), Warsaw (1929), Brussels (1929), Geneva (1930), Jassy (1934), Lausanne (1935), Basel (1936) and Athens (1937). In 1933, he was elected foreign member of the Boston American Academy of Arts and Sciences.
At the end of the 19th century, the Civil code of 1804 was still the major reference in French law. This Civil Code was inspired by the French Revolution principles, where judges were considered as the « mouth of the law » and obliged to apply it without any interpretations.However, François Gény decided to use an independent method based on the will of the law-maker. In his work Method of interpretation and sources of positive private law : a critical essay, published in 1899, François Gény declared that law has different implications. He noted that customs, tradition and scientific studies should be used to identify different interpretations of what is written in the law.In Science and technic in positive private law, published from 1914 to 1924, François Gény described a new method of interpretation called free scientific research with the goal to discover the origins of principles and rules. With this free scientific research, he based his studies on various "sciences" such as sociology, economics, linguistics, philosophy and theology, that previous law teachers had not used before.
In 1936, François Gény was part of a local political group called the Lorraine national gathering. This group campaigned against the French socialist government elected in 1936.
