Building an icon: the history of the HP 12C

In 1981, the world was obsessed by a little yellow "man" on a video screen and a fledgling cable network that played music on TV. And in an HP laboratory in Corvallis, Oregon, an Iowa farm-boy-turned-PhD was about to introduce a product that would literally turn the world on its side. That farm boy was HP Project Manager Dennis Harms and the product was the HP 12C Financial Calculator.

The HP 12C was the world’s first horizontal financial calculator. Its innovative design and breakthrough Reverse Polish Notation (RPN) entry forever changed the way students and professionals reach their goals. After 25 years, this iconic calculator is still sold under its original name and model number and retains its world-famous horizontal design.
