Alexander Overwijk

Beginning in 1996, to keep his class engaged, Overwijk would tell his students a story about being the "World Freehand Circle Drawing Champion." To further his claim, he would hand-draw a circle on the blackboard. In 2007, a video of Overwijk drawing a near-perfect circle for his class went viral on YouTube.^[5][6] Although the original story was a fabrication, he hosted a real "World Freehand Circle Drawing Championship" as a fundraiser for the Canadian Cancer Society following his viral fame.^[7]

In 2012, Overwijk and his circle-drawing abilities were featured on The Today Show.^[8] In 2018, a professor of the Department of Mathematics at Stockholm University found the drawing from the 2007 video to have a circularness of 99.7%.^[9]
