Elena Moiseeva

Elena Nikolaevna Moiseeva (Елена Николаевна Мойсеева) was born in 1897 as Elena Aleksandrovna Khaikman (Елена Александровна Хайкман). In 1903 she was adopted by Nadezhda von Meck's son Nikolai and Tchaikovsky's niece Anna, and thereby became Elena Nikolaevna von Meck (Елена Николаевна фон Мекк).

In 1917 she married Nikolai Sergeevich Moiseev (d. 1933), assistant professor at Moscow University, who was arrested in 1929 as part of Stalin's purges. The couple had two sons — Nikita (1917–2000), a scientist in the field of general mechanics and applied mathematics, and leading member of the Russian Academy of Science; and Sergei (1923–1948).

Elena Moiseeva died in 1926.
