The ability to undo an operation on a computer was independently invented multiple times, as a response to how people used computers.[1]
The File Retrieval and Editing System, developed starting in 1968 at Brown University, is reported to be the first computer-based system to have had an "undo" feature.[2][3]
Warren Teitelman developed a Programmer's Assistant as part of BBN-LISP with an Undo function, by 1971.
