A couple of weeks ago I met a philologist Larisa Kondratyeva, a neighbor of Ruben Orbeli granddaugher Olga Mandrika, who gave her before death a part of the archive left from her parents.
It contained a lot of interesting information, including the diagnosis and causes of Ruben Orbeli's death, May of 9, 1943, his lifetime and posthumous photos, as well as unique information
about the tragis fate of family members of his wife Olga Nikol'skaya and daugher Rusudan.
Thanks to the good will of Larisa Kondratyeva and the activity of HDS Russia this archive will transfered for research to the Library, Archive and The Institute of History of Natural Science
and Technology of Russian Academy of Sciences.
