6IDK. May be whoever had a sheet of paper, and noticed that you can roll it to form a tube without stretching. And then observed that if the material does stretch a bit, you could bend it to form a torus? Or may be a map-maker during a coffee break, who noticed that longitudes and latitudes would work very well on the surface of a donut. I really think that this metric on the torus is so natural that nobody would want his/her name associated with its discovery - and/or it was independently arrived at by very many people. – 2012-11-10
