Problem
I have a little history question, namely, as the title says, I am looking for early uses of trees (as a data structure, search tree, whatever) in computer science.
Solution
Wikipedia says that the first use of tree in mathematics was by Cayley in 1857.
Since the use in computer science is taken directly from mathematics, it seems more fundamental to ask when they originated there. Unless computer scientists originally called trees something else, the first computer scientist to use "tree" doesn't seem any more significant than, say, the first Australian to use "tree".
