Feinstein has been married three times. In 1956, Feinstein married Jack Berman (d. 2002), a colleague in the San Francisco District Attorney's Office. She and Berman divorced three years later. Their daughter, Katherine Feinstein Mariano (b. 1957), was the presiding judge of the San Francisco Superior Court for twelve years, through 2012. In 1962, shortly after beginning her career in politics, Feinstein married her second husband, neurosurgeon Bertram Feinstein, who died of colon cancer in 1978. In 1980, Feinstein married Richard C. Blum, an investment banker. In 2003, Feinstein was ranked the fifth-wealthiest senator, with an estimated net worth of US$26 million. By 2005 her net worth had increased to between US$43 million and US$99 million. Her 347-page financial-disclosure statement – characterized by the San Francisco Chronicle as "nearly the size of a phone book" – draws clear lines between her assets and those of her husband, with many of her assets in blind trusts.
