Jack Ruby, the Mafioso on 'The Umbrella Academy,' Is Based on a Historical Figure

Season 1 of The Umbrella Academy ended on a worrisome note, capturing how Vanya (Ellen Page) destroyed the world as we know it by taking out years and years' worth of pent-up frustration on a violin. 

Season 2 of the show plunges Vanya and her siblings into another near-apocalyptic scenario. This time, however, they are transported to Dallas, Tex. in the 1960s, where one of them even befriends Jack Ruby, the killer of Lee Harvey Oswald.

The next 10 episodes of The Umbrella Academy reference events like the assassination of 35th U.S. President John F. Kennedy and historical figures like Roscoe H. Hillenkoetter, the first director of the Central Intelligence Agency. 

In addition, the show also pays homage to a 1994 song by TLC, titled "Waterfalls," the 1978 hit by Gloria Gaynor, "I Will Survive," and the 1969 action-thriller, The Italian Job. 

This time around, each sibling is plunged into a different setting. Klaus (Robert Sheehan) starts a cult in San Francisco before making his way over to Dallas, Tex., while Allison (Emmy Raver-Lampman) joins sit-ins organized as part of the Civil Rights Movement. Luther lands a new gig at the Carousel Club, a Texas-based burlesque joint run by the mightily powerful mafioso, Jack Ruby. 

It is through Luther's storyline that we learn more about Ruby. As the show reveals, the influential nightclub owner helped facilitate activities like gambling, drug trafficking, and prostitution. He was also the killer of Lee Harvey Oswald, the former U.S. Marine who assassinated John F. Kennedy. 

According to Cosmopolitan, the show features Ruby's dachshund, Sheba. What's more, it even pays homage to a conspiracy theory, according to which Ruby was on good terms with at least one FBI informant. 

As the theory has it, Ruby even invited an agent to "watch the fireworks" together on the day Kennedy was murdered — which some interpret as a sign indicating that he was briefed about the attack in advance. 

The Umbrella Academy alludes to this in a storyline that sees Luther beg Ruby (John Kapelos) to use his connections to help him find Allison. 

If the plotline focusing on Ruby's story wasn't enough, the creators also included a reference to "The Umbrella Man," aka Louie Steven Witt, Women's Health Mag reveals. 

According to conspiracy theorists, Louie Steven Witt might have helped Lee Harvey Oswald carry out his hideous plan by shooting a poison dart in Kennedy's neck. 

Unlike any other bystander, the man wore an all-black outfit on the day of the assassination, holding out a black umbrella in the blistering hot weather. On the show, "The Umbrella Man" is shown as Sir Reginald Hargreeves (Colm Feore), the siblings' father, Den of Geek reveals. 

Season 2 of The Umbrella Academy is available on Netflix now.
