Some context: Wilhelm Justus Goebel was born January 4, 1856, in Albany Township, Bradford County, Pennsylvania, the son of Wilhelm and Augusta (Groenkle) Goebel, immigrants from Hanover, Germany. The first of four children, he was born two months premature and weighed less than three pounds. His father served as a private in Company B, 82nd Pennsylvania Infantry Regiment during the American Civil War, and Goebel's mother raised her children alone, teaching them much about their German heritage. Wilhelm spoke only German until the age of six, but embraced the culture of his birth country as well, adopting the English spelling of his name.
In 1887, James W. Bryan vacated his seat in the Kentucky Senate to pursue the office of lieutenant governor. Goebel decided to seek election to the vacant seat representing the Covington area. His platform of railroad regulation and championing labor causes, combined with the influence of Stevenson, his former partner, should have given Goebel an easy victory, but this was not to be. A third political party, the Union Labor party, had risen to power in the area with a platform similar to Goebel's. However, while Goebel had to stick close to his allies in the Democratic party, the Union Labor party courted the votes of both Democrats and Republicans, and made the election close - decided in Goebel's favor by a mere fifty-six votes.  With only the two years remaining in former senator Bryan's term to distinguish himself before a re-election bid, Goebel took aim at a large and popular target: the Louisville and Nashville Railroad. A proposal from pro-railroad legislators in the Kentucky House of Representatives to abolish Kentucky's Railroad Commission was passed and sent to the Senate. Senator Cassius M. Clay responded by proposing a committee to investigate lobbying by the railroad industry. Goebel served on the committee, which uncovered significant violations by the railroad lobby. Goebel also helped defeat the bill to abolish the Railroad Commission in the Senate. These actions made him a hero in his district. He ran for a full term as senator unopposed in 1889, and won another term in 1893 by a three-to-one margin over his Republican opponent.  In 1890, Goebel was a delegate to Kentucky's fourth constitutional convention, which produced the current Kentucky Constitution. Despite the high honor of being chosen as a delegate, Goebel showed little interest in participating in the process of creating a new constitution. The convention was in session for 250 days; Goebel was present for just 100 of them. He did, however, successfully secure the inclusion of the Railroad Commission in the new constitution. As a constitutional entity, the Commission could only be abolished by an amendment ratified by popular vote. This would effectively protect the Commission from ever being unilaterally dismantled by the General Assembly.

Some context: The Riddler (Edward Nigma) is a fictional supervillain appearing in American comic books published by DC Comics, commonly as an adversary of the superhero Batman. The character made his first appearance in Detective Comics #140 (October, 1948) and was created by Bill Finger and Dick Sprang. Depicted as a Gotham City criminal mastermind, the Riddler takes delight in incorporating riddles and puzzles into his plots, and leaves them as clues for the authorities and Batman to solve. The character is one of Batman's most enduring enemies and belongs to the collective of adversaries that make up Batman's rogues gallery.
The Riddler makes his first true appearance in the new DC continuity relaunch, DC Rebirth, in Batman #19. An inmate of Arkham once again, he rather cooperatively assists Bane in unlocking a high tech door, allowing Bane access to confront Batman.  In the eight-part story-arc "War of Jokes and Riddles", commencing with Batman Vol. 3 #25, flashbacks to a year after the events of "Zero Year" have Batman recounting the details of a war between Riddler and Joker. He is first seen in custody at the GCPD, assisting them in solving a variety of crimes, including locating Joker's whereabouts, before stabbing a police officer to death 26 times. Blackmailing the approaching guards with details of their children and families, Riddler walks out freely before intruding into Joker's office. Riddler seemingly offers the Joker a partnership, acknowledging that if either of the two men individually kill Batman, the other will be left forever unsatisfied. However the Joker shoots Riddler in the stomach and quickly departs, Batman appearing through the window and giving chase. Left in a pool of his own blood, Riddler rose to his feet and limped out of the office, seemingly unfazed.  Edward quickly healed from the wound, carving a question marked shaped scar over the wound, before murdering Dr. Jaime Knowles. Riddler is then seen meeting with Poison Ivy, discussing the Joker's need to rid anyone who could potentially kill Batman before him. The duo are then ambushed by gunmen working for Carmine Falcone under the orders of the Joker to kill Riddler within the hour. However Poison Ivy attacks the gunmen with her vines, allowing Edward and herself to leave.  Riddler eventually formed his team, consisting on himself, Poison Ivy, Scarecrow, Deathstroke, Clayface, Killer Croc, Two-Face, Firefly, and Victor Zsasz. Waging war on Joker's team across Gotham, Riddler is responsible for poisoning Charles Brown's son, resulting in his transformation into Kite Man who joins up with Joker's team consisting of Cluemaster, Deadshot, Mad Hatter, Man-Bat, Mr. Freeze, Penguin, Solomon Grundy, and Ventriloquist. The war continues, with Riddler and Joker claiming territories across Gotham, before Riddler, who'd convinced Batman to side with him during the conflict, blackmails and interrogates Kite Man into giving up Joker's location. However Batman, after a brief fight between him, Riddler and Joker, becomes disgusted by Riddler's actions and quickly grabs a blade, breaking his one rule of No Killing in order to stab Riddler. However Joker, who finally begins to laugh again, prevents Batman from doing so.  The present day Riddler shows up next in 'Deathstroke #25' as a member of The Society who have placed Deathstroke on trial for appearing to have reformed. Riddler, using Hector Hammond's abilities, convinces the Society that Deathstroke is indeed evil by showcasing a simulation of Deathstroke killing them all right before Deathstroke himself is kidnapped.
