Some context: Richard I (8 September 1157 - 6 April 1199) was King of England from 1189 until his death. He also ruled as Duke of Normandy, Aquitaine and Gascony, Lord of Cyprus, Count of Poitiers, Anjou, Maine, and Nantes, and was overlord of Brittany at various times during the same period. He was the third of five sons of King Henry II of England and Duchess Eleanor of Aquitaine. He was known as Richard Coeur de Lion or Richard the Lionheart because of his reputation as a great military leader and warrior.
Bad weather forced Richard's ship to put in at Corfu, in the lands of the Byzantine Emperor Isaac II Angelos, who objected to Richard's annexation of Cyprus, formerly Byzantine territory. Disguised as a Knight Templar, Richard sailed from Corfu with four attendants, but his ship was wrecked near Aquileia, forcing Richard and his party into a dangerous land route through central Europe. On his way to the territory of his brother-in-law Henry the Lion, Richard was captured shortly before Christmas 1192 near Vienna by Leopold V, Duke of Austria, who accused Richard of arranging the murder of his cousin Conrad of Montferrat. Moreover, Richard had personally offended Leopold by casting down his standard from the walls of Acre.  Duke Leopold kept him prisoner at Durnstein Castle under the care of Leopold's ministerialis Hadmar of Kuenring. His mishap was soon known to England, but the regents were for some weeks uncertain of his whereabouts. While in prison, Richard wrote Ja nus hons pris or Ja nuls om pres ("No man who is imprisoned"), which is addressed to his half-sister Marie de Champagne. He wrote the song, in French and Occitan versions, to express his feelings of abandonment by his people and his sister. The detention of a crusader was contrary to public law, and on these grounds Pope Celestine III excommunicated Duke Leopold.  On 28 March 1193 Richard was brought to Speyer and handed over to Henry VI, Holy Roman Emperor, who imprisoned him in Trifels Castle. Henry VI was aggrieved by the support the Plantagenets had given to the family of Henry the Lion and by Richard's recognition of Tancred in Sicily. Henry VI needed money to raise an army and assert his rights over southern Italy and continued to hold Richard for ransom. In response Pope Celestine III excommunicated Henry VI, as he had Duke Leopold, for the continued wrongful imprisonment of Richard. Richard famously refused to show deference to the emperor and declared to him, "I am born of a rank which recognises no superior but God". Despite his complaints, the conditions of his captivity were not severe.  The emperor demanded that 150,000 marks (100,000 pounds of silver) be delivered to him before he would release the king, the same amount raised by the Saladin tithe only a few years earlier, and 2-3 times the annual income for the English Crown under Richard. Eleanor of Aquitaine worked to raise the ransom. Both clergy and laymen were taxed for a quarter of the value of their property, the gold and silver treasures of the churches were confiscated, and money was raised from the scutage and the carucage taxes. At the same time, John, Richard's brother, and King Philip of France offered 80,000 marks for the Emperor to hold Richard prisoner until Michaelmas 1194. The emperor turned down the offer. The money to rescue the King was transferred to Germany by the emperor's ambassadors, but "at the king's peril" (had it been lost along the way, Richard would have been held responsible), and finally, on 4 February 1194 Richard was released. Philip sent a message to John: "Look to yourself; the devil is loose".

Some context: 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.
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.
