For this week's cover of TIME, we interviewed nine sets of high-achieving siblings to figure out what their childhoods had in common. We went looking for sets of siblings who didn't come from enormous family fortune or legacy, yet all went on to success in wildly different fields.
Take, for example, the Emanuel brothers: Zeke is a bioethicist and a vice provost at the University of Pennsylvania who helped design the Affordable Care Act, Rahm is the mayor of Chicago and President Obama's former chief of staff, and Ari created Hollywood talent agency William Morris Endeavor. Or the Wojcicki sisters. Susan is the CEO of YouTube, Janet is a professor of pediatrics and epidemiology at University of California, San Francisco, and Anne is the CEO and co-founder of genetics company 23andMe. Or the Rodriguez sisters, which include a private-equity partner, Ivelisse Rodriguez Simon, a medical clinic director, Rebecca Rodriguez, and a Golden-Globe winning actress, Gina Rodriguez. Or the Antonoff siblings, who design clothes (Rachel) and win Grammys, (Jack).
