The Curta mechanical calculator was designed by Curt Herzstark while imprisoned in Buchenwald concentration camp during World War II. Curta calculators Type 2 were produced from 1953 through 1970 and continued to be sold until about 1972 when the new electronic pocket calculators came on the market and the Curta could no longer compete. However, it remains an important artifact of mid-20th century engineering and a testament to the ingenuity of its creator. Two different models of the Curta were produced. The Type 1 has a result capacity of 11 digits and the Type 2, which generates results to 15 digits. The Type 2 has an 11 column keyboard, 15 digit results and an 8 digit revolution counter. It is 2.6" in diameter by 3.6" long and weighs 12.5 oz. The Curta was widely used by engineers, scientists, and mathematicians in the years following its release. Its compact design made it ideal for use in the field, and its reliability and accuracy made it a valuable tool for complex calculations. It was affectionately known as the "pepper grinder" or "peppermill" due to its shape and means of operation. It was also termed the math grenade due to its superficial resemblance to a certain type of hand grenade. Today, the Curta is highly prized by collectors and enthusiasts, who appreciate its elegant design and historical significance. It stands as a reminder of the power of human ingenuity, even in the darkest of circumstances.
