Andrew Madoff was one of Madoff's two sons. The other, Mark, committed suicide. Andrew Madoff grew up in Roslyn, on Long Island. He joined his father’s closely held wholesale trading house, Bernard L. Madoff Investment Securities, right after graduating from the Wharton School at the University of Pennsylvania in 1988. He worked alongside his brother at the firm’s trading desk in the Lipstick Building, on Third Avenue near 53rd Street, two floors away from the secretive money management operation at the heart of his father’s long-running fraud. Unlike his brother, Andrew refused to cringe from the spotlight or hide from critics. He helped his fiancée, Catherine Hooper, build a consulting firm to advise others on dealing with life-shattering developments. He joined with Ms. Hooper and his mother, Ruth Madoff, in promoting an authorized family biography, which was published in fall 2011. Besides his fiancée, Mr. Madoff is survived by his mother, his father and two daughters from a former marriage, Anne and Emily.
