Andrew Stuart Fastow (born 22 December 1961) was the chief financial officer of Enron Corporation until the U.S. Securities and Exchange Commission opened an investigation into his conduct in 2001. Fastow was one of the key figures behind the complex web of off-balance-sheet special purpose entities (limited partnerships which Enron controlled) used to conceal their massive losses. He is currently serving a six-year prison sentence for charges related to this conduct.
Fastow was born in Washington, D.C. He grew up in New Providence, New Jersey, the middle of three sons. His parents, Carl and Joan Fastow, worked in merchandising. Andy graduated from New Providence High School, where he took part in student government, played on the tennis team, and played in the school band. He was the sole student representative on the New Jersey State Board of Education.
Fastow graduated from Tufts University in 1983 with B.A.s in economics and Chinese. While there, he met his future wife, Lea Weingarten, whom he married in 1984. He and his wife are both Jewish and have 2 children. Her family had founded a grocery store chain in Houston and later entered the real estate business. Fastow and Weingarten both earned MBAs at Northwestern University and worked for Continental Illinois National Bank and Trust Company in Chicago.
