If you visit Westlawn Cemetery just outside Chicago, you'll find a simple granite headstone for the man who silenced Lee Harvey Oswald on live television. But carved right in the center of that marker is a bracketed childhood nickname: Jack "Sparky" Ruby. In part two of our special miniseries, we rewind the tape to the cobblestones of 1920s Chicago to meet the teenage Jacob Rubenstein long before the strip clubs, the mobsters, and the history-shattering events in Dealey Plaza. This is the story of a boy running wild on Roosevelt Street—a kid who refused to sit at a school desk, refused to work for a boss, and violently beat anyone who dared call him by his own name.
Following his designation as a dependent ward of the state in 1923, young Jacob was temporarily exiled to a rural Illinois foster farm—a quiet landscape that must have felt like another planet to a boy raised on the pavement of the Maxwell Street ghetto. Though his fractured family was loosely patched back together a couple of years later, the household remained a chaotic, disorganized pressure cooker. Jacob quickly sought his education on the streets, bouncing between grammar schools and repeating the third grade before dropping out permanently after the eighth grade at age sixteen. Traditional high school was an unaffordable luxury; for Jacob, survival meant money, and he made a lifelong rule: he would never work for a boss, choosing instead to survive on pure grit as a street hustler.
As the Great Depression squeezed the Chicago streets dry, Jacob's hustle took on many forms. He and his teenage friends became street-level ticket scalpers outside local ballparks and boxing arenas, which led to his first physical altercation with a police officer. Though he escaped charges through his brother's early political connections, the margins on the street grew razor-thin, pushing Jacob into a highly unusual black-market venture: printing and selling unauthorized bootleg copies of copyrighted sheet music. The scheme landed him a brief, humiliating stint behind bars, deepening his view of himself as an outsider who had to scrape, claw, and fight for every single dime.
During these formative years, Jacob’s personality split into two completely contradictory worlds. To some, he was a gentle, polite boy who idolized world welterweight champion Barney Ross. To others, he was a manic street brawler with a legendary hair-trigger temper who was obsessed with physical health and boasting he could hit harder than Joe Louis. Nothing triggered his volcanic rage faster than his childhood nickname "Sparky"—a name his sister Eva claimed mocked his awkward, wobbling walk like a comic strip horse, but his brother Hyman insisted was a badge of lightning speed and street intelligence. By 1933, with the Chicago streets dry and Al Capone's gangster empire fracturing, Jacob packed his bags for California carrying with him the deep insecurities and explosive temper that would one day seal his fate in a Dallas basement.
