# Lewis Perdue

Lewis Perdue (born May 1, 1949) is the author of 20 published books including Daughter of God, and The Da Vinci Legacy. Perdue was sued by Random House in 2003 when he charged that Dan Brown's The Da Vinci Code plagiarized those two books.

## Life

Perdue was born in the Mississippi Delta in 1949. He was expelled from the University of Mississippi in 1967 for leading a civil rights march.

He wrote the first book on how to upgrade IBM PCs, Supercharging Your PC: A Do-It Yourself Guide to Expanding the PC (1987).
In 1985, Perdue was named a vice president and managing director in San Jose for Manning Selvage & Lee. He founded the publication Wine Business Monthly in 1991, and has written two nonfiction books on the topic of wine: The French Paradox and Beyond: Live Longer with Wine and the Mediterranean Lifestyle (1992) and The Wrath of Grapes: The Coming Wine Industry Shakeout And How To Take Advantage Of It (1999).

## Plagiarism case

On April 11, 2005, novelist Lewis Perdue sued Brown and his publisher Random House for plagiarizing his novels The Da Vinci Legacy (1983) and Daughter of God (1999), claiming "there are far too many parallels between my books and The Da Vinci Code for it to be an accident." The director of Britain's Forensic Linguistics Institute, John Olsson, analyzed both books, and declared the "evidence of infringement is overwhelming" and "This is the most blatant example of in-your-face plagiarism I've ever seen... There are literally hundreds of parallels." However, Perdue was not allowed to introduce Olsson's statement at the Appeals Court hearing.
On August 4, 2005, District Judge George B. Daniels granted a motion for summary judgment and dismissed the suit, ruling that "a reasonable average lay observer would not conclude that The Da Vinci Code is substantially similar to Daughter of God. Any slightly similar elements are on the level of generalized or otherwise unprotectable ideas." He affirmed that The Da Vinci Code does not infringe upon copyrights held by Perdue.
