David Eppstein added a dubious – discuss template to the claim that appears in the article, that David Hirsch was the first to introduce the sphericon. Epstein claimed that Hirsch had been preceded by Collin Roberts and Alan Boeding. This is baseless for the following reasons:
• As can be seen in Hirsch's patent documents [1] he filed the patent in 1980. Colin Roberts published his discovery in an article by Ian Stewart 19 years later [2].
• The device (or sculpture) created by Alan Boeding does not seem to be a sphericon at all. The sphericon is a geometric shape. It is a solid made of two halves of a bi-cone. In the source associated with Boeding's work [3] he describes it as: "crosses from my religious faith and circles from my Boy Scout background when we would sing vespers around the campfire. We would make circles that would not close so there would be a place for someone new" What does that description have to do with the sphericon?
• Reading the source relating to Boeding's work reveals that Boeding himself did not claim to have published it in 1979. He says that he conceived it and created a prototype at that time. He himself notes that he started performing with it only two years later.
• The article was written by Boeding himself. Isn't there a need for an " in-depth published source independent from the inventor"? Thinkingarena ( talk) 21:05, 12 September 2020 (UTC)
