Abstract
In his " Introduction to Mathematical Philosophy," Bertrand Russell defines number as the class of similar classes. This definition was first given by Frege in 1884 but was practically ignored till it was rediscovered by Russell. I am not aware of any other definition of number by a mathematician.
