You may be familiar with the concept of multiple discovery, in which scientists coincidentially make similar discoveries independent of each other and around the same time period. Examples include Leibniz and Newton both discovering calculus, Darwin and Wallace both making discoveries on evolution, Bell and Gray both inventing the telephone, and so on.
I'm wondering if there are any examples of this same sort of thing in art history? Furthermore, I'm wondering if we see any examples of one-upmanship going on in the art world, throughout history. Were there ever any famous artists who started doing something brand new, only to have their ideas remixed by some young upstart? Are there any such patterns in the art world, of note?
