While women have yet to shatter the ultimate glass ceiling of the White House, they've been steadily scaling the towering heights of Wall Street since the 1960s. The author of the groundbreaking book "She Wolves: The Untold History of Women on Wall Street," historian Paulina Bren talks to me about how these trailblazers navigated the male-dominated world of finance. From Muriel Siebert becoming the first woman to own a NYSE seat in 1967 to the waves of female graduates entering finance in the 1980s, women transformed the financial sector despite facing persistent discrimination. Bren explains how these pioneering women rose from secretarial pools to trading floors and executive suites, reshaping one of America's most powerful industries.
