Mohsen Hashtroodi (; also transliterated Hachtroudi or Hashtroudi) was an Iranian mathematician, public intellectual, and popular lecturer. A student of ÃÂlie Cartan, he worked in differential geometry; his doctoral work led to what is now called the Hachtroudi connection.
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 DÃÂr al-Fonà «n in 1925. He subsequently went to France on a government scholarship to study mathematics at the Sorbonne, earning a licence (1935) and a doctorat dâÂÂÃÂtat (1937) under ÃÂlie Cartan. His thesis, Les espaces dâÂÂéléments àconnexion projective normale, was published by Hermann (Actualités scientifiques et industrielles, no. 505) and is available online.
Back in Iran he taught at DÃÂneà ¡sarÃÂ-ye ÿÃÂli 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).
He was a member at the Institute for Advanced Study (School of Mathematics), Princeton, in OctoberâÂÂDecember 1951. He attended several International Congresses of Mathematicians, including 1950 (Cambridge, Massachusetts), 1954 (Amsterdam), and 1958 (Edinburgh).
Hashtroodi married RobÃÂb Modiri in 1944; they had three children (Faranak, FaribÃÂ, and Ramin). He died in Tehran on 4 September 1976 and is buried at Behesht-e Zahra cemetery, Tehran.
The Iranian Mathematical Society awards the Hashtroudi Award in geometry and topology in his honour.
