Arnold Neustadter (25 August 1910 – 17 April 1996) was an American inventor and businessman. With Danish engineer Hildaur Neilson, he invented the Rolodex desktop rotating card file and other office equipment.
His earlier inventions included the Autodex, a spring-operated phone directory that automatically opened to the selected letter, Swivodex, an inkwell that did not spill, Punchodex, a paper hole puncher, and Clipodex, a transcription aid that attached to a stenographer's knee.
The Rolodex has been called "a triumph of low technology" and "a lasting symbol of the art of networking".
