Problem: Background: Fazlur Rahman Khan (Bengali: phjlur rhmaan khaan, Fozlur Rohman Khan) (3 April 1929 - 27 March 1982) was a Bangladeshi-American structural engineer and architect, who initiated important structural systems for skyscrapers. Considered the "father of tubular designs" for high-rises, Khan was also a pioneer in computer-aided design (CAD). He was the designer of the Sears Tower, since renamed Willis Tower, the tallest building in the world from 1973 until 1998, and the 100-story John Hancock Center. Khan, more than any other individual, ushered in a renaissance in skyscraper construction during the second half of the 20th century.
Context: Among Khan's other accomplishments, he received the Wason Medal (1971) and Alfred Lindau Award (1973) from the American Concrete Institute (ACI); the Thomas Middlebrooks Award (1972) and the Ernest Howard Award (1977) from ASCE; the Kimbrough Medal (1973) from the American Institute of Steel Construction; the Oscar Faber medal (1973) from the Institution of Structural Engineers, London; the International Award of Merit in Structural Engineering (1983) from the International Association for Bridge and Structural Engineering IABSE; the AIA Institute Honor for Distinguished Achievement (1983) from the American Institute of Architects; and the John Parmer Award (1987) from Structural Engineers Association of Illinois and Illinois Engineering Hall of Fame from Illinois Engineering Council (2006).  Khan was cited five times by Engineering News-Record as among those who served the best interests of the construction industry, and in 1972 he was honoured with ENR's Man of the Year award. In 1973 he was elected to the National Academy of Engineering. He received Honorary Doctorates from Northwestern University, Lehigh University, and the Swiss Federal Institute of Technology Zurich (ETH Zurich).  The Council on Tall Buildings and Urban Habitat named one of their CTBUH Skyscraper Awards the Fazlur Khan Lifetime Achievement Medal after him, and other awards have been established in his honour, along with a chair at Lehigh University. Promoting educational activities and research, the Fazlur Rahman Khan Endowed Chair of Structural Engineering and Architecture honours Khan's legacy of engineering advancement and architectural sensibility. Dan Frangopol is the first holder of the chair.  Khan was mentioned by president Obama in 2009 in his speech in Cairo, Egypt when he cited the achievements of America's Muslim citizens.  Khan was the subject of the Google Doodle on April 3, 2017, marking what would have been his 88th birthday.
Question: What was he the chair of?
Answer: the Fazlur Rahman Khan Endowed Chair of Structural Engineering and Architecture honours Khan's legacy of engineering advancement and architectural sensibility.

Problem: Background: The Birth of a Nation (originally called The Clansman) is a 1915 American silent epic drama film directed and co-produced by D. W. Griffith and starring Lillian Gish. The screenplay is adapted from the novel and play The Clansman, both by Thomas Dixon Jr., as well as Dixon's novel The Leopard's Spots. Griffith co-wrote the screenplay with Frank E. Woods, and co-produced the film with Harry Aitken. It was released on February 8, 1915.
Context: Thomas Dixon, Jr. was a former classmate of then-president Woodrow Wilson at Johns Hopkins University. Dixon arranged a screening of The Birth of a Nation at the White House for Wilson, members of his cabinet, and their families, in one of the first ever screenings at the White House. Wilson was falsely reported to have said of the film, "It is like writing history with lightning. And my only regret is that it is all so terribly true". Wilson's aide, Joseph Tumulty, denied the claims and said that "the President was entirely unaware of the nature of the play before it was presented and at no time has expressed his approbation of it." Historians believe the quote attributed to Wilson originated with Dixon, who was relentless in publicizing the film. After controversy over the film had grown, Wilson wrote that he disapproved of the "unfortunate production".  Besides having the film screened at the White House, Dixon persuaded all nine justices of the Supreme Count to attend a screening of The Birth of a Nation as well as many members of Congress. With the help of the Navy Secretary, Josephus Daniels, Dixon was able to meet the Chief Justice of the Supreme Court, Edward Douglass White. Initially Justice White was not interested in seeing the film, but when Dixon told him it was the "true story" of Reconstruction and the Klan's role in "saving the South", White, recalling his youth in Louisiana, jumped to attention and said: "I was a member of the Klan, sir". With White agreeing to see the film, the rest of the Supreme Court followed. Dixon was clearly rattled and upset by criticism by African-Americans that the film version of his books was projecting hatred against them, and wanted the endorsement of many powerful men as possible to offset such criticism. Dixon always vehemently denied having anti-black prejudices--despite the way his books promoted white supremacy--and stated: "My books are hard reading for a Negro, and yet the Negroes, in denouncing them, are unwittingly denouncing one of their greatest friends".  In a letter sent on May 1, 1915, to Joseph P. Tumulty, the press secretary to President Wilson, Dixon wrote: "The real purpose of my film was to revolutionize Northern sentiments by a presentation of history that would transform every man in the audience into a good Democrat...Every man who comes out of the theater is a Southern partisan for life!" In a letter to President Wilson sent on September 5, 1915, Dixon boasted: "This play is transforming the entire population of the North and the West into sympathetic Southern voters. There will never be an issue of your segregation policy". Dixon was alluding to the fact that Wilson upon becoming president in 1913 had imposed segregation on federal workplaces in Washington D.C. while reducing the number of black employees through demotion or dismissal.
Question: How did Dixon persuade them

Dixon told him it was the "true story" of Reconstruction and the Klan's role in "saving the South",
