Luigi Illica (9 May 1857 – 16 December 1919) was an Italian librettist who wrote for Giacomo Puccini (usually with Giuseppe Giacosa), Pietro Mascagni, Alfredo Catalani, Umberto Giordano, Baron Alberto Franchetti and other important Italian composers. His most famous opera libretti are those for La bohème, Tosca, Madama Butterfly and Andrea Chénier.

Illica was born at Castell'Arquato. His personal life sometimes imitated his libretti. The reason he is always photographed with his head slightly turned is because he lost his right ear in a duel over a woman. When silent films based on Illica's operas were made, his name appeared in large letters on advertisements because distributors could only guarantee that his stories would be used, and not that they would be accompanied by the music of the appropriate composer.
As a playwright of considerable quality, he is today remembered through one of Italy's oldest awards, the Luigi Illica International Prize founded in 1961, which goes to world famous opera singers, opera conductors, directors and authors. The prize is now awarded every two years and alternates with the Illica Opera Stage International Competition, which offers prizes and debut opportunities to young singers.

Friedrich Christiansen (12 December 1879 – 3 December 1972) was a German general who served as commander of the German Wehrmacht in the occupied Netherlands during World War II.
Christiansen was a World War I flying ace and the only seaplane pilot to receive the Pour le Mérite. He joined the Nazi Party in the interwar period, eventually rising to the rank of Korpsführer of the National Socialist Flyers Corps. After the German invasion of the Netherlands, Christiansen was appointed as the Wehrmachtbefehlshaber (Chief Military Commander) in the Netherlands. In response to attacks by the Dutch Resistance, he ordered reprisals against Dutch civilians such as the Putten raid. He was also responsible for the Dutch famine of 1944–1945 that resulted in the deaths of thousands of civilians after ordering an embargo on all food transports to the western Netherlands. After the war, Christiansen was arrested and convicted of war crimes.
