Abel, Niels Henrik 1802-1829. Norwegian mathematician. He demonstrated that the general quintic equation ax^5 + bx^4 + cx^3 + dx^2 + ex + f = 0 could not be solved algebraically. Subsequent work covered elliptic functions, integral equations, infinite series, and the binomial theorem. He lived a life of poverty and ill health, dying of tuberculosis shortly before the arrival of an offer of a postion at the University of Berlin. Subject by: Russell Webb
