The HP-35 was the epitome of a revolutionary mousetrap. Hand-held four function calculators were already on the market. Few could imagine a machine with scientific calculation capability that would fit in your shirt pocket, but many could readily see the use and the need started growing in their minds. Developed by Hewlett-Packard
Company in Palo Alto, California at 1501 Page Mill Road and introduced in 1972, the HP-35 was the first full-function, shirt-pocket-sized, scientific calculator. This invention revolutionized the profession by allowing the engineer to make almost instantaneous, extremely accurate scientific calculations, at home, office or in the field. The HP-35 was the innovative culmination of mechanical design, state-of-the-art technology, algorithm development and application; all unique at that time.
