Stefan Karl

Stefán Karl Stefánsson (July 10, 1975 – August 21, 2018) was an Icelandic actor, best known for his role as Robbie Rotten in LazyTown.

Early life
Stefánsson was born in the town of Hafnarfjörður, Iceland on July 10, 1975, where he grew up and lived for most of his life. In 2004, he moved to the United States.

Personal life
Following Stefánsson's announcement in October 2016 that he had been diagnosed with pancreatic cancer, a GoFundMe campaign was created by LazyTown head writer Mark Valenti to pay his living costs when he fell too ill to work. The campaign was popularized by SilvaGunner uploading a parody of Stefánsson's work, which led to the song "We Are Number One" from LazyTown becoming an internet meme. As of June 11, 2017, the campaign had raised over $121,000, surpassing its goal of $100,000. To thank contributors, Stefánsson held a live stream on Facebook on 11 December 2016, where he performed the song with the other actors from the music video.

On May 19, 2017, his wife announced on Facebook that his cancer had relapsed and two masses on his liver have to be surgically removed.

On June 21, 2017, Stefánsson's wife Steinunn Ólína Þorsteinsdóttir posted on Facebook that the cancer has once again metastasized and has reached Stage IV, meaning that he would most likely not survive. She states in her post, "Although the chances and statistics are not in our favor, and Stefán's candle burns quickly, we will not be scared of fear."
