Excerpt from Introduction to the Theory of Algebraic Equations
But, of all the sources, the lectures and publications of Professor Bolza have been of the greatest aid to the author. In particular, the examples 65) of the group of an equation have been borrowed with his permission from his lectures. The present elementary presentation of the theory is the out come Oi lectures delivered by the author in 1897 at the University of California, in 1899 at the University of Texas, and twice in 1902 at the University of Chicago.
Leonard Eugene Dickson (January 22, 1874 – January 17, 1954) was an American mathematician. He was one of the first American researchers in abstract algebra, in particular the theory of finite fields and classical groups, and is also remembered for a three-volume history of number theory, History of the Theory of Numbers.
