Stefán Karl Stefánsson (; ; 10 July 1975 – 21 August 2018) was an Icelandic actor and singer. He was best known for playing antagonist Robbie Rotten on the children's television series "LazyTown".
Career.
Stefán Karl's career started in 1994. At the age of 19, he worked as a puppeteer for television. During his years as a puppeteer, he had also been studying at the Drama Academy of Iceland. However, he was not satisfied with how Iceland views their drama standards. He remembers that his principal at his high school said that "acting is not about making faces and changing your face". He did not agree with his high school principal.
Later, Stefán Karl had been invited by Magnús Scheving, an Icelandic gymnast, to portray one of the characters in the second "LazyTown" play. Scheving created the plays because he was concerned that Iceland's younger generation is not doing enough exercise. Stefán Karl explained that "[Scheving] wanted the kids to get healthier, so he created this musical called "LazyTown". He played Sportacus, the fitness fanatic, and I was Robbie Rotten, the guy who liked to stay indoors and sleep". After initial success with the musical, Nickelodeon eventually made a deal with the creators of "LazyTown" to air the first 40 episodes of "LazyTown" along with a special studio built in Iceland. During the first few years of "LazyTown" in the early 2000s, Stefán Karl initially knew no English, but soon became fluent.
Personal life.
Stefán Karl lived in Los Angeles with his wife Steinunn Ólína Þorsteinsdóttir, three daughters, and one son. In June 2018, he was awarded the Order of the Falcon.

On the same month, GoFundMe campaign was subsequently created by "LazyTown" head writer Mark Valenti to pay his living costs when he became too ill to work. The campaign was popularized by various YouTube users uploading parodies of Stefán Karl's work. This eventually made the songs "We Are Number One" and "The Mine Song" from "LazyTown" become Internet memes. In August 2017, Stefán Karl stated he was in remission. He clarified on his GoFundMe campaign that while his metastases had been removed after successful liver surgery in June 2017, he still had the disease and had refused further adjuvant therapy.
In March 2018, Stefán Karl was diagnosed with inoperable bile duct cancer, and said that he was undergoing chemotherapy to increase the length of his life. In April 2018, he announced that he personally chose to stop his chemotherapy, and then began to shut down all his social media accounts.
He died on 21 August 2018 at the age of 43. His wife stated that Stefansson didn't want to a funeral when he died. Instead, she had said that his body will be secretly scattered into a distant ocean.
