(CNN) -- Before Robin Williams, there was Jonathan Winters.
Winters begat Williams, if only in comedic spirit.
To understand the genius of Williams, an audience must look to Winters.
They were kindred clowns, and even as you read their names now, you wonder what jokes each comic would have conjured up seeing their surnames side by side, W with W.
Winters was the original master of funny characters created out of the thin air of a stage, Williams once pronounced. Winters could invent them with nothing more than a stick as a prop.
Winters became a deity to Williams. In fact, he was the "Comedy Buddha," as the protégé put it.
"Jonathan Winters is the reason I became a comedian," Williams declared.
Indeed, Winters' influence began in Williams' childhood, when he saw how his father belly-laughed at Winters on television.
A rush of insight overwhelmed the boy named Robin: The way to his stern father's heart was through imitating Winters.
That's how Robin Williams the prodigy was born.
"My dad was a sweet man, but not an easy laugh," Williams wrote in The New York Times in an homage to Winters shortly after his death in 2013 at age 87. "My father's laughter introduced me to the comedy of Jonathan Winters."
The father and son were watching Jack Paar on "The Tonight Show" when Winters appeared as a guest, wearing a pith helmet, Williams recounted in the Times.
"Who are you?" Paar asked.
"I'm a great white hunter," Winters said in an effete voice. "I hunt mainly squirrels."
"How do you do that?"
"I aim for their little nuts."
Williams repeated this tale often. The moment put him on the path to become one of America's funniest and most prolific artists, until this week when he apparently ended his life at age 63.
The epiphany of his life came in boyhood, while in front of a television screen, he said.
"My dad and I lost it. Seeing my father laugh like that made me think, 'Who is this guy and what's he on?' " Williams wrote in 2013.
The symbiosis lasted throughout Williams' career, except Williams was a far more hyperactive comic. Pity the co-star with whom he shared a stage. There was no way to stop Williams when he was on a roll.
Winters, in contrast, enjoyed a pause. He evoked an era before technology decimated our attention spans.
What the two masters shared was an irrepressible mischief, delivering joke upon joke with originality and freshness that left audiences wondering, how do they do it?
"Once upon a time, I called Jonathan my mentor and he immediately corrected me and said, 'Please,' he told me, 'I prefer idol,' " Williams said, drawing laughter from an audience gathered for the 2008 TV Land Awards.
Williams presented the Pioneer Award to Winters at that event.
"Jonathan Winters is my idol, and he is a true pioneer," Williams added in a rare moment of seriousness.
It wasn't the first time the mentor and the protégé shared a telecast.
When the acolyte surpassed the master and became a bigger name in show business, he and his producers invited Winters to join Williams' successful sitcom "Mork & Mindy" in 1981.
It could have made for an awkward moment: Winters was clearly the journeyman, in his late 50s; Williams was turning 30 that year. After all, Winters was better known to the generation of Williams' parents. Winters' namesake show aired in 1956, when Williams was 5.
What would Hollywood do? In a clever move, the show employed a role reversal. Winters emerged from an egg as a middle-aged offspring of Williams' Mork and Pam Dawber's Mindy.
The image of Winters as an infant born to Williams was an example of the two comics' imaginative powers.
"Jonathan's improvs on 'Mork & Mindy' were legendary," Williams wrote in the Times. "People on the Paramount lot would pack the sound stage on the nights we filmed him. ... Sometimes I would join in (on his bit), but I felt like a kazoo player sitting in with Coltrane."
Winters cast a long shadow in Williams' work, comedian Gilbert Gottfried said.
"When you watch Robin Williams, you can see a lot of Jonathan Winters. Robin is the first one to admit that; he worshiped Jonathan Winters. He insisted that Jonathan be written in as a regular on 'Mork and Mindy.' They wrote him in as an overgrown child, which was perfect casting," Gottfried wrote for CNN in a tribute to Winters shortly after his death.
Their shared backgrounds weren't all laughs, however.
Both men knew darkness. Inner battles took them to the brink.
Winters suffered two nervous breakdowns, in 1959 and 1961, according to the Internet Movie Database. He even voluntarily spent time in a private mental institution in his early 30s. And, like Williams, Winters also saw uneasy moments with his father, a banker who became an alcoholic after losing everything in the Great Depression, IMDB says. When in his room away from his parents, who later divorced, Winters invented characters to amuse himself.
Winters was a manic depressive, or bipolar, and described to National Public Radio in 2011 how, "I need that pain — whatever it is — to call upon it from time to time, no matter how bad it was."
Williams' descents into the abyss are well known because he openly spoke about them. He was an alcoholic who suffered relapse, costing him his second of three marriages. He abused cocaine, and made jokes about it afterward.
He also suffered depression -- so hard to imagine between all the laughs -- and at the time of his death, he was being treated for a severe bout that now seems more serious than he ever allowed his audiences to know.
Whatever hardships they endured, both jesters left a legacy that is unconquerable: a public court that is still laughing and a world of characters as richly pluralized as the names of Winters and Williams.
