Early Life and Education
Jean Louis Maximilian van Heijenoort was born in Creil, France, to a working-class family of Dutch and French descent. His father, Jan Theodore Didier van Heijenoort, immigrated to France from the Netherlands. Heijenoort's mother, Charlotte Helene Balagny, was a French Catholic.
Jean experienced hardship and poverty during his childhood. His father died in World War I, and the family endured French chauvinism against those with German or Dutch surnames. Despite these challenges, Heijenoort excelled in school and studied mathematics, philosophy, physics, chemistry, and languages.
Political Activism and Trotsky's Secretary
Heijenoort joined the Young Communist League as a teenager. Later, he became a Trotskyist and joined the Communist League, the French section of the International Left Opposition. In 1932, he was selected to become Leon Trotsky's personal secretary.
Heijenoort accompanied Trotsky on various trips, including a visit to Copenhagen and a move to Mexico. He served as Trotsky's secretary for seven years, until 1939. During this time, he witnessed Trotsky's work and ideas firsthand.
Life in the United States
In 1939, Heijenoort moved to New York City with his second wife, Beatrice Geiger. He became involved in the Socialist Workers Party in the United States and contributed articles to various Trotskyist and radical publications.
Despite being targeted during the McCarthy era, Heijenoort continued to write and publish under pseudonyms. He obtained a Ph.D. in mathematics from New York University in 1949.
Academic Career and Historical Contributions
Heijenoort's academic career focused on logic and the foundations of mathematics. He taught at Columbia University, Brandeis University, and Stanford University.
In 1967, he published "Source Book in Mathematical Logic, 1879-1931," an anthology of translated works that included the first complete translation of Gottlob Frege's "Begriffsschrift." This anthology became a seminal text in the field of mathematical logic.
Heijenoort's historiographical work played a significant role in shaping the understanding of the history of modern logic. His research and writings helped establish the importance of Frege's contributions and the development of the field.
Legacy
Jean van Heijenoort made significant contributions to political activism, Trotskyism, and the field of logic. His work as Trotsky's secretary and his historical research provide valuable insights into these intellectual and political movements.
