Question:
Ramis was born on November 21, 1944, in Chicago, Illinois, the son of Ruth (nee Cokee) and Nathan Ramis, who owned the Ace Food & Liquor Mart on the city's far North Side. Ramis had a Jewish upbringing. In his adult life, he did not practice any religion. He graduated from Stephen K. Hayt Elementary School in June 1958 and Nicholas Senn High School in 1962, both Chicago public schools, and in 1966 from Washington University in St. Louis, Missouri, where he was a member of the Alpha Xi chapter of Zeta Beta Tau fraternity.
In May 2010, Ramis contracted an infection that resulted in complications from autoimmune inflammatory vasculitis and lost the ability to walk. After relearning to walk he suffered a relapse of the disease in late 2011. He died of complications of the disease on February 24, 2014 at his home on Chicago's North Shore, at age 69. A private funeral was held for him two days later with family, friends, and several collaborators in attendance including Dan Aykroyd, Chevy Chase, Eugene Levy, Dave Thomas, David Pasquesi, Andrew Alexander, and the widows of John Belushi and Bernard Sahlins. He is buried at Shalom Memorial Park in Arlington Heights. Upon Ramis' death, President Barack Obama released a statement, saying: "when we watched his movies--from Animal House and Caddyshack to Ghostbusters and Groundhog Day--we didn't just laugh until it hurt. We questioned authority. We identified with the outsider. We rooted for the underdog. And through it all, we never lost our faith in happy endings." He ended his statement by saying he hoped Ramis "received total consciousness", in reference to a line from Caddyshack. Ramis and longtime collaborator Bill Murray had a falling out during the filming of Groundhog Day. Shortly before Ramis' death Murray visited him, and the two spoke for the first time in 21 years. Murray gave tribute to Ramis at the 86th Academy Awards. Ramis was paid tribute by Stephen Colbert on an episode of his show The Colbert Report. Colbert said that "as a young, bookish man with glasses looking for a role model, I might have picked Harold Ramis". He ended the show by thanking Ramis.

input: The initial lineup of Exodus was formed in the late 1970s by guitarists Kirk Hammett and Tim Agnello, drummer/vocalist Tom Hunting, and vocalist Keith Stewart while attending high school together. The band added bass guitarist Carlton Melson in 1980, and the quintet began making a name for themselves playing backyard parties and various school functions. They played mostly cover songs in the vein of 1970s hard rock and New wave of British heavy metal (NWOBHM) acts but also developed some of their own original songs. Things with Stewart did not work out, and Hunting became the band's sole vocalist for some time. Carlton Melson was replaced in 1981 by bass guitarist Geoff Andrews. Tim Agnello would leave the group soon after to pursue a life of ministry in Stockton, California, leaving Exodus to perform as a power trio until a replacement was found in Hammett's friend and Exodus roadie Gary Holt. Also in 1981, Hammett met El Cerrito resident Paul Baloff at a North Berkeley house party, a friendship that was started - according to Hammett - by their shared admiration for punk rock and 1970s heavy metal music. Baloff became the band's lead vocalist and the quintet recorded a 3-track demo tape in 1982 consisting of the songs "Whipping Queen", "Death and Domination" and "Warlord", a release which would be Hammett's only recording with Exodus. The band's music began to incorporate elements of hardcore punk into their NWOBHM roots, and Exodus were considered the pioneers of the Bay Area thrash metal scene. In November 1982, Exodus opened a show at San Francisco's Old Waldorf venue for Metallica, a then-relatively unknown (and unsigned) band from Los Angeles. As the band began playing more shows in Bay Area clubs, they gained a large, fervent fan base known for their violent concert behavior. In early 1983, Hammett left Exodus to join Metallica on the recommendation of Mark Whitaker, leaving Gary Holt to effectively take creative control of the band. Hammett was replaced short term by Mike Maung, followed by Evan McCaskey, before the band finally found a permanent replacement in guitarist Rick Hunolt. Geoff Andrews also left to start an early incarnation of pioneering death metal band Possessed, and was replaced by bass guitarist Rob McKillop. In the spring of 1984, Exodus entered Turk Street Studios with producer Doug Piercy to record demos of songs that would later appear on their debut album. The band was signed to New York-based Torrid Records and Exodus prepared to enter Prairie Sun Recording Studios that summer.

Answer the question at the end by quoting:

Dan Gerhard Brown was born on June 22, 1964 in Exeter, New Hampshire. He has a younger sister, Valerie (born 1968) and brother, Gregory (born 1975). Brown attended Exeter's public schools until the ninth grade. He grew up on the campus of Phillips Exeter Academy, where his father, Richard G. Brown, was a teacher of mathematics and wrote textbooks from 1968 until his retirement in 1997.
In August 2005 author Lewis Perdue unsuccessfully sued Brown for plagiarism, on the basis of claimed similarity between The Da Vinci Code and his novels, The Da Vinci Legacy (1983) and Daughter of God (2000). Judge George Daniels said, in part: "A reasonable average lay observer would not conclude that The Da Vinci Code is substantially similar to Daughter of God." In April 2006 Brown's publisher, Random House, won a copyright infringement case brought by authors Michael Baigent and Richard Leigh, who claimed that Brown stole ideas from their 1982 book Holy Blood Holy Grail for his 2003 novel The Da Vinci Code. It was in the book Holy Blood Holy Grail that Baigent, Leigh, and co-author Henry Lincoln had advanced the theory that Jesus and Mary Magdalene married and had a child and that the bloodline continues to this day. Brown apparently alluded to the two authors' names in his book. Leigh Teabing, a lead character in both the novel and the film, uses Leigh's name as the first name, and anagrammatically derives his last name from Baigent's. Mr Justice Peter Smith found in Brown's favor in the case, and as a private amusement, embedded his own Smithy code in the written judgment. On March 28, 2007, Brown's publisher, Random House, won an appeal copyright infringement case. The Court of Appeal of England and Wales rejected the efforts from Baigent and Leigh, who became liable for paying legal expenses of nearly US$6 million. Brown has been sued twice in U.S. Federal courts by the author Jack Dunn who claims Brown copied a huge part of his book The Vatican Boys to write The Da Vinci Code (2006-07) and Angels & Demons (2011-12). Both lawsuits were not allowed to go to a jury trial. In 2017, in London, another claim was begun against Brown by Jack Dunn who claimed that Justice was not served in the U.S. lawsuits.

why did he sue?
Daniels said, in part: "A reasonable average lay observer would not conclude that The Da Vinci Code is substantially similar to Daughter of God."
