Katherine Esau studied botany in three different languages — Russian, Germany and English — before committing to share her discoveries with the United States.
Esau spent most of her career studying plant anatomy and the effects of viruses in plants. Today, botanists and biologists still use her research as the basis for their own studies.
But working and living in the United States was not her original plan.
Esau grew up in Ukraine in the early 1900s. Her father was mayor of her hometown Yekaterinoslav —now called Dnepropetrovsk.
During the Bolshevik Revolution, Esau’s father was removed from office and the family feared for his safety. Her family fled Ukraine in 1918 and traveled by train more than 1,000 miles to Berlin, Germany. The trip, which would have normally taken two days, took two weeks to complete.
In 1922, Esau and her family immigrated to California, where she began her graduate work and eventually became a professor.
