St Petersburg Saint Petersburg ( rus, links=no, Санкт-Петербург, a=Ru-Sankt Peterburg Leningrad Petrograd Piter.ogg, r=Sankt-Peterburg, p=ˈsankt pʲɪtʲɪrˈburk), formerly known as Petrograd (1914–1924) and later Leningrad (1924–1991), i ...

and his mother a teacher at said school, thus the young Alekandrov spent a majority of his childhood in the city. His family was old Russian nobility—students noted ancestral portraits which hung in his office. His sisters were Soviet botanist Vera Danilovna Aleksandrov (RU) and Maria Danilovna Aleksandrova, author of the first monograph on gerontopsychology in the USSR. In 1937, he married a student of the Faculty of Physics, Marianna Leonidovna Georg. Together they had two children: Daria (b. 1948) and Daniil (RU) (b. 1957). In 1980, he married Svetlana Mikhailovna Vladimirova (nee Bogacheva). In 1951 he became a member of the

Mountaineering

Aleksandrov became attracted to alpinism under the influence of his advisor

. In the summer of 1937, after defending his D.Sc., :''…together with I. Chashnikov he makes a first climb to the Chotchi summit, and with K. Piskaryov performs a climb of Bu-Ul'gen via the western wall (one of the first wall climbs in the history of the Soviet alpinism).
��/nowiki> In 1940 he participates in a record-making traversal ��/nowiki> He manages, almost by a miracle, to stop the fall of A. Gromov, who had fallen along with a snow shelf. It was with this traversal that Aleksandrov completed the alpinist sports master requirements. The German-Soviet War postponed awarding him this honorary title until 1949.'' During his rectorship, Aleksandrov also advanced the mountaineering sport activities in the university, actively participating in the climbs. The fiftieth birthday was celebrated by Aleksandrov in the mountains with his friends. On that day he made a solo first climb of an : ''…unnamed peak 6222 m (Shakhdarinsk ridge, Pamir), that as he suggested was then named "The peak of the Leningrad university."'' During later years Aleksandrov was unable to climb due to health problems, yet he never ceased dreaming of climbing. Finally, in 1982, the year of his seventieth birthday, he, together with K. Tolstov, performed in
