Jean Louis Maxime van Heijenoort /vænˈh.ənɔːrt/ (French: [van ɛjɛnɔʁt]; July 23, 1912 – March 29, 1986) was a historian of mathematical logic. He was also a personal secretary to Leon Trotsky from 1932 to 1939, and from then until 1947, an American Trotskyist activist.

Life

Van Heijenoort was born in Creil in France. His family's financial situation was difficult as his father, after having immigrated from the Netherlands, died when van Heijenoort was two. He nevertheless completed normal education, which enabled him to be fluent in French. He remained attached to his French extended family and friends until his death and visited France twice a year after he became a naturalized American citizen in 1958. He was murdered in Mexico City in 1986 by his fourth spouse.

Political views

In 1932, Van Heijenoort was recruited by Yvan Craipeau to join the Trotskyist movement. He joined the Communist League in the same year. After Trotsky was exiled, he hired van Heijenoort as a secretary and a bodyguard, primarily because of his fluency in French, Russian, German, and English. Van Heijenoort spent seven years in Trotsky's household, during which he served as a translator, helped Trotsky write several books and carried on an extensive intellectual and political correspondence in several languages.

In 1939, van Heijenoort moved to New York City to his second wife, Beatrice "Bunny" Guyer. He was not involved in the circumstances leading to Trotsky's murder in 1940. In New York, he worked for the Socialist Workers Party (US) (SWP) and wrote a number of articles for the American Trotskyist press and other radical outlets. He was elected to the secretariat of the Fourth International in 1940 but resigned when Felix Morrow and Albert Goldman, with whom he had sided, were expelled from the SWP. (Goldman subsequently joined the US Workers Party while Morrow did not join any other party or grouping.) In 1947, he too was expelled from the SWP. In 1948, he published an article, entitled "A Century's Balance Sheet", in which he criticized that part of Marxism which saw the "proletariat" as the revolutionary class. He continued to hold other parts of Marxism as true.

Van Heijenoort was spared the ordeal of McCarthyism because everything he published in Trotskyist organisms appeared under a pen name, which he had over a dozen of.[1][permanent dead link] Moreover, according to Feferman (1993), Van Heijenoort the logician was quite reserved about his Trotskyist youth, and did not discuss politics. Nevertheless, he contributed to the Trotskyist movement until the last decade of his life, when he wrote his monograph With Trotsky in Exile (1978), and an edition of Trotsky's correspondence (1980), and advised and collaborated with the archivists at the Houghton Library in Harvard University, which holds many of Trotsky's papers from his years in exile.

Academic work

After completing a Ph.D. in mathematics at New York University in 1949 under the supervision of J. J. Stoker, Van Heijenoort taught mathematics there, but he redirected towards logic and philosophy of mathematics, largely under the influence of Georg Kreisel. He started teaching philosophy, first part-time at Columbia University, then full-time at Brandeis University from 1965 to 1977.[1] He spent much of his last decade at Stanford University, writing and editing eight books, including parts of the Collected Works of Kurt Gödel.

The Source Book (van Heijenoort 1967) is an anthology of translations, on the history of logic and the foundations of mathematics. It begins with the first complete translation of Frege's 1879 Begriffsschrift. This is followed by 45 historically important short pieces on mathematical logic and axiomatic set theory, originally published between 1889 and 1931. The anthology ends with Gödel's landmark paper on the incompletability of Peano arithmetic. For more information on the period covered by this anthology, see Grattan-Guinness (2000).

Nearly all the content of the Source Book had only been available in the best North American university libraries (e.g., even the Library of Congress did not acquire a copy of the Begriffsschrift until 1964), and all but four pieces had to be translated from one of six continental European languages. When possible, the authors of the original texts reviewed the translations, and suggested corrections and amendments. Each piece was supplied with editorial footnotes and an introduction (mostly by Van Heijenoort but some by Willard Quine and Burton Dreben); its references were combined into a comprehensive bibliography, and misprints, inconsistencies, and errors were corrected.

The Source Book contributed to advancing the view that modern logic begins with, and builds on, the Begriffsschrift. Grattan-Guinness (2000) argues that this perspective on the history of logic is mistaken, because Frege employed an idiosyncratic notation and was significantly less read than e.g. Peano. Ironically, van Heijenoort (1967a) is often cited by those who prefer the alternative model theoretic stance on logic and mathematics. Much of the history of that stance, whose leading lights include George Boole, Charles Sanders Peirce, Ernst Schröder, Leopold Löwenheim, Thoralf Skolem, Alfred Tarski, and Jaakko Hintikka, is covered in Brady (2000). The Source Book underrated the algebraic logic of De Morgan, Boole, Peirce, and Schröder, but devoted more pages to Skolem than to anyone other than Frege, and included Löwenheim (1915), the founding paper on model theory.

Personal life

Van Heijenoort had children with two of his four wives. While living with Trotsky in Coyoacán, van Heijenoort's first wife left him after an argument with Trotsky's spouse. During a visit to his estranged fourth wife, Anne-Marie Zamora, daughter of Trotsky's lawyer, in Mexico City in 1986, she murdered him,[2] before taking her own life.

Van Heijenoort was also one of Frida Kahlo's lovers; in the film Frida, he is played by Felipe Fulop.
