Trần Đức Thảo (Từ Sơn, Bắc Ninh, 26 September 1917 – Paris, 24 April 1993) was a Vietnamese philosopher. His work (written primarily in French) attempted to unite phenomenology with Marxist philosophy. His work had some currency in France in the 1950s and 1960s, and was cited favorably by Jacques Derrida, Jean-François Lyotard and Louis Althusser. Life Studies in France Trần Đức Thảo was born in Hanoi, French Indochina, he was educated there, completing his baccalaureate at 17. In 1936, he continued his studies in France, becoming a student of Maurice Merleau-Ponty at the École Normale Supérieure where he wrote a dissertation for a diplôme d’études supérieures on Hegel. In 1943, he completed his agrégation with a thesis on the phenomenology of Edmund Husserl, being received premier ex aequo alongside Jules Vuillemin. Through the 1940s, he worked on his first book, Phenomenology and Dialectical Materialism.

From October to December 1945, Trần Đức Thảo was jailed by the French government as a threat to its security. Return to Vietnam, 1951 Phenomenology and Dialectical Materialism was published in 1951, and in the same year he returned to Vietnam, working in support of the Communist Party. In 1956, he was named the Dean of History in the country's first national university. But he became critical of the Party over land reforms which had led to many deaths in 1956, and Trần Đức Thảo was caught up in the Nhan Van-Giai Pham affair in which the dissident intellectuals of the late 1950s were publicly criticized or punished. Though Tran Duc Thao was never jailed, he fell out of favor with the ruling Party, publishing two self-criticisms in Nhân Dân and leaving his position of authority in 1958. None of his work was published in his home country from 1965 until 1987.
