Ronald Kent Shelp (born 1941) is the author of "Fallen Giant: The Amazing Story of Hank Greenberg and the History of AIG".
 Shelp worked for Maurice "Hank" Greenberg, CEO of American International Group, for 12 years, ultimately serving as worldwide head of government relations.
 "Fallen Giant" is a 2006 non-fiction book that tracks AIG from its first business transaction in China in 1919, through its growth into a global financial services powerhouse, to Greenberg's exit in 2005 after accusations of fraud by New York Attorney General Eliot Spitzer.
 The contributions of C.V. Starr, AIG's founder, and Greenberg, who led the company for 37 years, are chronicled in the book.
 It was updated several times during the financial crisis that began in 2008, when the US government seized control of AIG by lending the company $85 billion in exchange for a 79.9% equity stake, making the American taxpayer AIG’s largest shareholder.
"Fallen Giant" was translated and published in China, Taiwan, and Korea.
George William Pipgras (December 20, 1899 – October 19, 1986) was an American right-handed starting pitcher and umpire in Major League Baseball.
 Known as "The Danish Viking", he spent most of his playing career with the New York Yankees, breaking in as a rookie in 1923.
 He spent the 1925 and 1926 seasons in the minor leagues, and became a starter in the rotation for the first time with the legendary 1927 team.
 Pipgras lead the American League in wins with a 24–13, 3.38 ERA record for the following year's 1928 repeat champions.
 After ending his 11-year career with the Boston Red Sox, he became an AL umpire from 1938 to 1946.
 He was the umpire behind the plate in one of baseball's most dramatic wins ever: on September 30, 1945, at St. Louis' Sportsman's Park, when Hank Greenberg hit a ninth inning Grand Slam, after Pipgras suggested to Greenberg that the game should be called on account of darkness.
 Greenberg convinced him that "he" could still see the ball, so the game proceeded.
 The next pitch was hit over the fence and the Tigers won the pennant, and eventually the 1945 World Series.
 His younger brother Ed pitched briefly for the 1932 Brooklyn Dodgers.
The Life and Times of Hank Greenberg is a 1998 documentary film directed, produced and written by Aviva Kempner about Hall of Fame first baseman Hank Greenberg of the Detroit Tigers.
 A Jewish player who chose not to play on Yom Kippur in 1934 during a heated pennant race, Greenberg experienced a great deal of antisemitism.
 He nearly broke Babe Ruth's 60 home run record by hitting 58 home runs in 1938.
Aviva Kempner (born December 23, 1946) is an American filmmaker.
 Her documentaries investigate non-stereotypical images of Jews in history and focus on the untold stories of Jewish people.
 She is most well known for "The Life and Times of Hank Greenberg".
The 1949 Cleveland Indians season was the 49th in franchise history.
 The club entered the season as the defending World Champions.
 On March 5, 1949, Indians minority owner Bob Hope donned a Cleveland Indians uniform and posed with manager Lou Boudreau and vice president Hank Greenberg as the World Series champions opened spring training camp in Tucson, Arizona.
Harry Albert Davis (May 7, 1908 – March 3, 1997), nicknamed "Stinky", was the Detroit Tigers first baseman who lost his job when Hank Greenberg joined the Tigers in 1933.
 Stinky Davis was the Tigers' starting first baseman in 1932.
 That year, he hit .269 with a .339 on-base percentage, 92 runs scored, 159 hits, and 74 RBIs.
 Despite decent numbers, Davis lost his starting job to Greenberg in 1933.
 He played 66 games at first base in 1933 before Greenberg took over.
 After 1933, Davis dropped out of the major leagues for four years before being given a second chance by the St. Louis Browns in 1937.
 He played in 120 games for the Browns and hit .276 with a .374 on-base percentage.
 Stinky Davis was born and died in Shreveport, Louisiana.
The Brooklyn Bushwicks were an independent, semi-professional baseball team that played its games almost totally in Dexter Park in Queens from 1913 to 1951.
 They were unique at their time for fielding multi-ethnic rosters.
 They played what amounts to exhibition games against barnstorming Negro league teams, minor league baseball teams, and other semi-pro teams.
 The Bushwicks were owned by Max Rosner, who hired many former major league to play on his club, including Dazzy Vance and others.
 All the famous players of the time came to play exhibitions at Dexter Park including Dizzy Dean, Hank Greenberg, Joe DiMaggio, Babe Ruth, Lou Gehrig, and Joe Medwick.
 Until he became friends with Rosner, Ruth demanded upfront payments in cash before agreeing to personal appearances.
 The DiMaggio picture was taken during his debut year with Yankees.
Wenming Xiaoshi (; "Short History of Civilization" or "A Brief History of Modern Times" or "A Brief History of Enlightenment") is a novel by Li Baojia (Li Boyuan).
 The novel is a satire of pseudo-reformers in the Qing Dynasty period who found difficulty adjusting to modernization, including its complexities and problems.
 The work has 60 chapters but it is a shorter work than "Officialdom Unmasked".
The 1990 Detroit Tigers season was the 90th season in franchise history.
 The Tigers finished in third place in the American League East, with a record of 79-83.
 They scored 750 runs and allowed 754.
 Notably, Cecil Fielder reached the 50 Home Run plateau, the first and last Detroit Tiger to hit at least 50 home runs since Hank Greenberg in 1938.
A Brief History of Time is a 1991 biographical documentary film about the physicist Stephen Hawking, directed by Errol Morris.
 The title derives from Hawking's bestselling book "A Brief History of Time", but whereas the book is an explanation of cosmology, the film is a biography of Hawking's life, featuring interviews with family members, colleagues, and even his childhood nanny.
 The music is by frequent Morris collaborator, Philip Glass.
