Robert Dugen was standing on the deck of his $35 million Miami penthouse, 57 floors above Biscayne Bay, when he picked up a balsa wood plane and sent it sailing into the open sky. The scene captures something essential about the 82-year-old decabillionaire: a man who built and sold a cancer treatment company for $21 billion, yet still marks his mornings by watching little paper-thin gliders ride the updrafts off the water below. For anyone who has ever wondered what drive looks like after the money stops mattering, Dugen’s answer is right there in the thermals.
From $5,000 and a worried phone call to a billion dollars in a single day
Dugen grew up in a family of seven where, by the end of the month, the household was scraping together change for a burger. His father earned $800. Dugen’s first paying job came at 50 cents an hour, and even that was mostly in stock that he watched climb rather than cash he could spend. A mentor put him in front of his first investment with $5,000. From there he ran it to $3.6 million, lost most of it through distraction, landed at $600,000, and then made a move that surprised even him: he gave $200,000 of what remained to a church. ‘They’re going to use it better than I was,’ he said at the time, and turned the rest into a focused rebuild. Billionaire status arrived in his 40s. The single largest day came later, when a company milestone cleared a billion dollars in one trading session. His celebration for crossing the million-dollar mark years earlier had been an ice cream sandwich with extra vanilla on the side at a local restaurant, because that was what felt right.
The philosophy he credits with getting him there came from an uncle who caught him spiraling over the possibility of losing his $5,000 stake. The uncle’s response was blunt: stop putting your attention on losing it and start putting it on making it. Dugen still frames that exchange as the most useful piece of advice he ever received. ‘What’s the ROI for worry?’ he said on Brickell Avenue. ‘You get stressed, you get strained, you get tired. You’ve got to take the viewpoint: I can and will make it happen.’
The loss that redirected a fortune toward cancer research
Dugen’s lowest moment had nothing to do with markets. His son died at 26 from a glioblastoma. After the loss, he looked at a struggling biotech company and decided the mission mattered more than the risk. He built it into a cancer treatment operation over the following three decades, and eventually sold it for $21 billion. He has been fighting cancer every day since, now tracking how artificial intelligence is collapsing the timeline from problem identification to resolution. He believes the work can now move at five times the speed it could before.
At 82, Dugen does not look the part of someone coasting. Every morning before the interview crew arrived, he was submerging his arm past the elbow in a cold plunge set to 38 degrees. He bikes for an hour and a half through mountain terrain in Costa Rica. He surfs. On the penthouse deck, a sculpture of a panther crouches near the entrance, positioned, as Dugen put it, to give visitors a nod as they come in. On the wall of his office hangs a Caltech psychologist’s framework listing the 24 personality traits found in historical geniuses, a chart he reads as a practical instruction manual rather than an academic curiosity.
He flew private to Miami and pays full taxes on everything, after writing a $100 million California tax check for five months of residency and deciding that was the end of that chapter. His view on taxes is direct: ‘Pay all the taxes you can, because you get to keep the balance. It’s an honor.’
The balsa wood plane still in the air over Brickell
His record for a balsa wood plane launched from the 57th floor stands at five minutes of flight time, a personal best he first chased as a kid and can now pursue with the advantage of altitude.
When Dugen talks about how he wants to be remembered, he does not reach for the dollar figures. He reaches for the word ‘awakening.’ The goal, as he describes it, is to remind people that the capacity for what he calls genius-level operation is already present in them, waiting to be activated. The balsa wood plane he launched that morning over Biscayne Bay caught an updraft, climbed briefly above the railing, and held there longer than it had any practical reason to.
