Biologist Nelson Rebello, known as Oil Man, dies in Curitiba after attacking his own dog and suffering a pulmonary embolism

Nelson Rebello, widely recognized as Oil Man, passed away at 64 on Saturday morning, March 29, in Curitiba, coinciding with the city’s 332nd anniversary celebration. The biologist, a beloved local character known for roaming the streets in a swimsuit covered in bronzing oil, had been hospitalized at the Evangelical Mackenzie University Hospital since Monday, March 24, following an attack by his own dog at his home in the Bacacheri neighborhood. The official cause of death was reported as cardiorespiratory arrest, possibly linked to a suspected pulmonary embolism stemming from the incident. His death stunned residents and officials alike, who praised him as a cultural symbol of the city.

A graduate in Biological Sciences from the Federal University of Paraná (UFPR) and a retired professor, Rebello crafted the Oil Man persona over two decades ago, becoming a fixture in Curitiba’s streets and parks. His distinctive look—wearing only a swimsuit, sneakers, and a glistening coat of oil—captured the attention of locals and visitors, earning him a unique place in the city’s identity. The nickname originated from a playful encounter: a couple likened him to the superhero Iron Man, jokingly suggesting that “oil” defined his version. The oil recipe, a personal blend he applied daily, remained a closely guarded secret, adding to his mystique.

The incident leading to his hospitalization unfolded unexpectedly. On Monday afternoon, as Rebello entered his home, he tripped and fell over his dog, a mixed-breed companion sharing his space. Startled, the animal bit him, injuring his arm and dislocating his left shoulder. Emergency services, including Samu and the Fire Department, rushed him first to Cajuru Hospital before transferring him to Evangelical Mackenzie Hospital, where his condition deteriorated over the week, resulting in his death early Saturday.

Details of the attack that shook Oil Man’s routine

The dog attack took place at Rebello’s residence on Estados Unidos Street in Bacacheri, catching neighbors and acquaintances off guard. Witnesses noted that Rebello appeared alert during the rescue, chatting with responders as he was stretchered away. The injuries included puncture bites to his ankle and arm, along with a shoulder dislocation, though initial assessments by paramedics suggested no immediate life-threatening risk.

Described as a medium-sized mutt, the dog had no prior record of aggression. Its reaction was likely triggered by the sudden fall, prompting it to bite in self-defense. Firefighters restrained the animal to ensure safe access for the rescue team. Neighbors emphasized the dog’s usual docility, often seen alongside Rebello during his neighborhood strolls, making the incident all the more shocking to those familiar with his daily life.

Footage from the scene captured Rebello being loaded into an ambulance, his arm bandaged and bite marks visible. Though his condition seemed manageable at first, hospitalization uncovered graver complications. Doctors suspected a pulmonary embolism—where blood clots obstruct lung arteries—as a potential outcome of the trauma, though further tests are pending to establish a definitive link between the attack and his death.

Journey of a one-of-a-kind character

Nelson Rebello’s Oil Man persona emerged in 1997, blending simplicity with eccentricity. After years of teaching following his UFPR graduation, he retired and fully embraced the role that would define him. Whether cycling or walking through Curitiba’s downtown, he became a familiar sight, often spotted pushing his bike while showcasing his oiled, tanned physique. His approachable nature shone through—he willingly posed for photos and engaged with passersby, always with a warm smile.

For over 20 years, Rebello frequented iconic spots like Rua XV de Novembro, the Botanical Garden, and Barigui Park. His daily treks, often spanning hours, showcased his dedication to a lifestyle he crafted with care. The oil wasn’t just for show; he believed it protected his skin and boosted his well-being, a ritual that became synonymous with his identity and fueled the Oil Man legend.

Paraná Governor Carlos Massa Ratinho Junior paid tribute to Rebello on social media, calling him a symbol of Curitiba’s spirit.
