Merge Sort

Algorithm

A divide-and-conquer sorting algorithm invented by John von Neumann in 1945, one of the earliest algorithms described specifically for an electronic computer, with a fuller analysis appearing in a 1948 report by Goldstine and von Neumann.

Core Principle
Split the input in half, recursively sort each half, then merge the two sorted halves back together in linear time, giving guaranteed O(n log n) performance regardless of the input's starting order. 1

Frequently Asked Questions

Who invented merge sort and when?

John von Neumann invented it in 1945.

John von Neumann invented merge sort in 1945, which makes it one of the earliest algorithms described specifically for an electronic computer. A fuller analysis appeared in a 1948 report by Goldstine and von Neumann. The method splits the input in half, sorts each half recursively, then merges the two sorted halves back together.
