**Scipione dal Ferro** lectured at Bologna where he was a colleague of Pacioli. Dal Ferro is the first to solve the cubic equation by radicals. He only solved one of the two cases (the fact that 0 and negative numbers were not in use made many distinct cases). He kept his discovery secret and only told his student Fior shortly before his death. Ferrari reports seeing a notebook in del Ferro's handwriting where the solution is clearly written down.
