Mohsen Hashtroodi (محسن هشترودی; also transliterated Hachtroudi or Hashtroudi) was an Iranian mathematician, public intellectual, and popular lecturer. A student of Élie Cartan, he worked in differential geometry; his doctoral work led to what is now called the Hachtroudi connection.[1][2]

Life

[edit]

Hashtroodi was born in Tabriz on 12 January 1907, received his primary education there, and moved to Tehran where he completed secondary school at the Dār al-Fonūn in 1925.[1] He subsequently went to France on a government scholarship to study mathematics at the Sorbonne, earning a licence (1935) and a doctorat d’État (1937) under Élie Cartan.[1] His thesis, Les espaces d’éléments à connexion projective normale, was published by Hermann (Actualités scientifiques et industrielles, no. 505) and is available online.[3][4][5][6]

Back in Iran he taught at Dānešsarā-ye ʿāli and the University of Tehran (professor, 1941). He later served as president of the University of Tabriz (1951) and as dean of science at the University of Tehran (1957).[1]

He was a member at the Institute for Advanced Study (School of Mathematics), Princeton, in October–December 1951.[7] He attended several International Congresses of Mathematicians, including 1950 (Cambridge, Massachusetts), 1954 (Amsterdam), and 1958 (Edinburgh).[8][9][10]

Hashtroodi married Robāb Modiri in 1944; they had three children (Faranak, Faribā, and Ramin). He died in Tehran on 4 September 1976 and is buried at Behesht-e Zahra cemetery, Tehran.[11]

Legacy
