Susan Gutfreund is the widow of John Gutfreund, “the king of Wall Street,” a one-time chief executive of Salomon Brothers, an investment bank, who died in early March 2016. He was 86. She was his second wife. Her previous marriage, to John Roby Penn, whose family owned real estate in Texas, ended in divorce in 1976. Before she married Penn, she worked as a flight attendant for Pan Am. Her husband, who led Salomon until 1991, including during its initial public offering, personified the ascendancy and excess of 1980s Wall Street milieu. Before Salomon started the trend of going public, investment banks in New York were all private partnerships.
