Claire Zillman is a London-based senior editor for Fortune, where she writes and edits features about corporate leadership, with a focus on female executives. She also edits Fortune's flagship newsletter, CEO Daily, and co-chairs Fortune's Most Powerful Women Summit. Her Fortune cover story, "The First Lady of Wall Street," about Jane Fraser's rise to become the first female CEO among Wall Street's big banks earned her a SABEW, and her feature on the then-unbroken glass ceiling at Wall Street’s banking giants won a New York Press Award. Claire has also worked for Fortune in New York and Hong Kong. Earlier in her career, she was a reporter for The American Lawyer magazine. She graduated with honors from Syracuse University with degrees in journalism and history and is originally from Chicago. She lives in East London with her husband and son.
