Erland Samuel Bring

Bring had developed an important transformation to simplify a quintic equation to the form ${\displaystyle x^{5}+px+q=0}$ (see Bring radical). In 1832–35 the same transformation was independently derived by George Jerrard. However, whereas Jerrard knew from the past work by Paolo Ruffini and Niels Henrik Abel that a general quintic equation can not be solved, this fact was not known to Bring, putting him in a disadvantage.[1]
