My great grandma was the last person in her family to leave Belarus. She never spoke English. She would clean bathrooms during the night shift, and put every dime she made into U.S. savings bonds.”
Rometty’s grandma—twice widowed—hand-made lampshades to make ends meet. Then, her father left her mother penniless. She’d never worked a day outside her home, or had a traditional job.
