How did the Russian Revolution of 1917 affect Ayn Rand’s family?

The Russian Revolution of 1917 significantly disrupted the life of Ayn Rand and her family. Her father, Zinovy Rosenbaum, was a prosperous pharmacist whose shop was confiscated by communist authorities following the revolution—an event that Rand deeply resented.1

In the wake of the tsarist regime's overthrow, the family fled to Crimea, where Rand completed her high school education. She eventually returned to Russia in 1921 to attend university before securing an opportunity to emigrate to the United States in 1926.21
