Louis Leitz

In 1896, he made some important changes to the development of ring binders, in Stuttgart-Feuerbach.

Leitz created the lever arch file, a standing binder with a riveted lever arch mechanism (the lever can be easily opened, closed and locked) and space-saving slots into the cover, thereby introducing the modern ring binder.

[1][2] In 1911, he introduced the "finger hole" on the side of the binder to aid removal from crowded shelves.

The Louis Leitz Foundation was founded in his memory on 30 November 2001.
