input: Historians rate Frederick II as a highly significant European monarch of the Middle Ages. This reputation was present even in Frederick's era. Lansing and English, two British historians, argue that medieval Palermo has been overlooked in favor of Paris and London:  One effect of this approach has been to privilege historical winners, [and] aspects of medieval Europe that became important in later centuries, above all the nation state.... Arguably the liveliest cultural innovation in the 13th century was Mediterranean, centered on Frederick II's polyglot court and administration in Palermo.... Sicily and the Italian South in later centuries suffered a long slide into overtaxed poverty and marginality. Textbook narratives therefore focus not on medieval Palermo, with its Muslim and Jewish bureaucracies and Arabic-speaking monarch, but on the historical winners, Paris and London.  Modern medievalists no longer accept the notion, sponsored by the popes, of Frederick as an anti-Christian. They argue that Frederick understood himself as a Christian monarch in the sense of a Byzantine emperor, thus as God's "viceroy" on earth. Whatever his personal feelings toward religion, certainly submission to the pope did not enter into the matter in the slightest. This was in line with the Hohenstaufen Kaiser-Idee, the ideology claiming the Holy Roman Emperor to be the legitimate successor to the Roman Emperors.  20th century treatments of Frederick vary from the sober (Wolfgang Sturner) to the dramatic (Ernst Kantorowicz). However, all agree on Frederick II's significance as Holy Roman Emperor. In the judgment of British historian Geoffrey Barraclough, Frederick's extensive concessions to German princes--which he made in the hopes of securing his base for his Italian projects--undid the political power of his predecessors and postponed German unity for centuries.  However, the modern approach to Frederick II tends to be focused on the continuity between Frederick and his predecessors as Kings of Sicily and Holy Roman Emperors, and the similarities between him and other thirteenth-century monarchs. David Abulafia, in a biography subtitled "A Medieval Emperor," argues that Frederick's reputation as an enlightened figure ahead of his time is undeserved, and that Frederick was mostly a conventionally Christian monarch who sought to rule in a conventional medieval manner.

input: Ripken owns several minor league baseball teams. In 2002, he purchased the Utica Blue Sox of the New York-Penn League and moved them to his hometown of Aberdeen, renaming them the Aberdeen IronBirds. The team is the Short-season Single-A affiliate team in the Orioles' system and plays at Ripken Stadium. On June 28, 2005, he announced that he was purchasing the Augusta GreenJackets of the South Atlantic League, a Single-A affiliate of the San Francisco Giants. At the end of the 2008 season, Ripken purchased the Vero Beach Devil Rays of the Single-A advanced Florida State League and moved them to Port Charlotte, Florida, where they were renamed the Charlotte Stone Crabs.  On January 10, 2007, Ripken expressed interest in purchasing the Baltimore Orioles if current owner Peter Angelos were to sell the team. He had yet to be approached about the potential purchase of the team. Though he has not purchased them, Ripken was quoted in a July 17, 2010, Associated Press article as saying he would consider rejoining the Orioles part-time as an advisor and full-time after his son graduated from high school in 2012.  In October 2007, Ripken began working as a studio analyst for TBS Sports during the 2007 Major League Baseball playoffs. He has continued to serve in this role since then.  Ripken is on the Board of Directors of ZeniMax Media. On February 28, 2008, Ripken announced his venture into the massively multiplayer online sports game market with "Cal Ripken's Real Baseball".  The Ripken Experience is a group of sports complexes. The first opened in Aberdeen, Maryland. A second location with nine baseball fields is located in Myrtle Beach, South Carolina. Opened in 2006, it cost $26 million with $7 million more spent since then. A third location is set to open in summer 2016 in Pigeon Forge, Tennessee.

input: Carnegie did not want to marry during his mother's lifetime, instead choosing to take care of her in her illness towards the end of her life. After she died in 1886, the 51-year-old Carnegie married Louise Whitfield, who was 21 years his junior. In 1897, the couple had their only child, a daughter, whom they named after Carnegie's mother, Margaret.  Carnegie made his fortune in the steel industry, controlling the most extensive integrated iron and steel operations ever owned by an individual in the United States. One of his two great innovations was in the cheap and efficient mass production of steel by adopting and adapting the Bessemer process, which allowed the high carbon content of pig iron to be burnt away in a controlled and rapid way during steel production. Steel prices dropped as a result, and Bessemer steel was rapidly adopted for rails; however, it was not suitable for buildings and bridges.  The second was in his vertical integration of all suppliers of raw materials. In the late 1880s, Carnegie Steel was the largest manufacturer of pig iron, steel rails, and coke in the world, with a capacity to produce approximately 2,000 tons of pig metal per day. In 1883, Carnegie bought the rival Homestead Steel Works, which included an extensive plant served by tributary coal and iron fields, a 425-mile (684 km) long railway, and a line of lake steamships. Carnegie combined his assets and those of his associates in 1892 with the launching of the Carnegie Steel Company.  By 1889, the U.S. output of steel exceeded that of the UK, and Carnegie owned a large part of it. Carnegie's empire grew to include the J. Edgar Thomson Steel Works in Braddock, (named for John Edgar Thomson, Carnegie's former boss and president of the Pennsylvania Railroad), Pittsburgh Bessemer Steel Works, the Lucy Furnaces, the Union Iron Mills, the Union Mill (Wilson, Walker & County), the Keystone Bridge Works, the Hartman Steel Works, the Frick Coke Company, and the Scotia ore mines. Carnegie, through Keystone, supplied the steel for and owned shares in the landmark Eads Bridge project across the Mississippi River at St. Louis, Missouri (completed 1874). This project was an important proof-of-concept for steel technology, which marked the opening of a new steel market.
