In Tehran, Hessabi was affiliated with the University of Tehran and organized the science and engineering faculties of the university. He was the teacher of Alenush Terian while she studied at the university.<ref>{{cite journal | doi = 10.1007/s00016-012-0085-x | volume=14 | issue=2 | title=Alenush Terian: The Iranian Solar Mother|year=2012 | journal=Physics in Perspective | pages=239–241 | last1 = Talebian | first1 = Mohammad | last2 = Talebian | first2 = Ehsan| bibcode=2012PhP....14..239T | s2cid=120601020 | doi-access=free }}</ref> In June 1951, Hessabi was appointed to a three-man provincial board of the Iranian oil company, the designated successor of the Anglo-Iranian Oil Company.

During the congress honoring "60 Years of Physics in Iran," his services were celebrated, and he was dubbed "the father of modern physics in Iran."

==Museum== In 1992 his house changed to a museum to for recognition of his life. The Mahmoud Hessabi museum is located Tajrish neighbourhood in Tehran.

The Hessabi family is part of Iran's Muslim elite. One of the capital's avenues is named after them, leading to a square with a statue of Dr. Hessabi. Mahmoud Hessabi had a son and a daughter. His son, an engineering graduate, is head of the Dr. Hessabi Institute (2015). Today, the majority of the family lives outside Iran, particularly following the 1979 Islamic Revolution.
