With the publication of his Zoroaster (a translation of the Gāthās of the Avesta, consisting of seventeen hymns attributed to Zoroaster) in 1948, Duchesne-Guillemin became one of the major figures in the study of the Avestan language of ancient Iran.^[1] At different times in his career, he lectured at Columbia University, the University of Chicago, and the University of California at Los Angeles.^[2] His 1962 La Religion de l’Iran Ancien is still considered a masterpiece and the best scholarly introduction to Zoroastrianism despite the decades of subsequent developments in the scholarship of the religion.^[2] His international reputation culminated in his appointment, in 1973, as editor of the series Acta Iranica.^[1]

In 1974, Duchesne-Guillemin was awarded an honorary doctorate from the University of Tehran.^[1]
