[4] Alasgar Mammadov was born on 10 October 1919 in Keshla, Baku and was raised by his uncle due to premature death of his parents.

[5] After graduating from seven-year high school,[5] Mammadov studied at the Baku Industrial Technical College named after Nariman Narimanov in 1933–1937 and at the German language department of the Azerbaijan State Pedagogical Institute in 1937–1941.

[1][5] Since February 1945, Mammadov had started working as a chief reviewer in the People's Commissariat for Foreign Affairs of the USSR.

[7] Later, Alasgar Mammadov mentioned the following memories in his interviews about the Nuremberg Tribunal: 24 major military criminals were involved in the trial, but only 21 of them sat in the dock; Gustav Krupp, one of the main offenders, was terminally ill, while Robert Ley took his own life, and Martin Bormann had disappeared.

[8]Since August 1947, after marrying Shovkat khanim,[5] Mammadov had started teaching and scientific activities at the Faculty of Oriental Studies of Baku State University.

[12] Mammadov's first 573-page Arabic Language textbook was published in 1958 in the Soviet Union with an initial print run of 5,000 copies and used not only in Azerbaijan, but also in Tajikistan and Uzbekistan.

[10] His Арабский язык (Arabic Language) textbook, written in Russian, meets the needs of educators in oriental studies centers of Dagestan, Tatarstan, Ukraine, Central Asian Republics and other Post-Soviet states.
