99-year-old Irene Bergman, financial adviser at Stralem & Co., sits for a photograph at her home in New York, U.S., on Saturday, May 30, 2015. As one of the oldest working professionals in an industry run by men half her age, Bergman offers a rare perspective. She recalls the small private firms founded by German Jews of the 19th century that came to define Wall Street before their partnership model gave way to public listings, and honor succumbed to an ever-fiercer push for profit.
