Who first invented calculator?
The invention of the calculator is attributed to several individuals who made significant contributions over time. Here are a few key milestones in the development of calculators:
Abacus: The abacus, a counting tool, is considered one of the earliest calculators. Its exact origin is uncertain, but ancient civilizations such as the Sumerians, Egyptians, Greeks, and Chinese used different variations of the abacus for performing basic arithmetic calculations.
Mechanical Calculators: The development of mechanical calculators began in the 17th century. Blaise Pascal, a French mathematician, invented the Pascaline in 1642. It was a mechanical calculator capable of performing addition and subtraction through a series of gears and wheels.
Calculating Machines: In the 19th century, inventors continued to enhance mechanical calculators. Thomas de Colmar, a French inventor, created the Arithmometer in 1820, which was the first successful commercial calculator capable of performing all four arithmetic operations.
Key-driven Calculators: The next major development came with the introduction of key-driven calculators. In the late 19th century, inventors such as Willgodt T. Odhner, Dorr E. Felt, and Frank S. Baldwin designed and produced key-driven calculators that were easier to use and more efficient.
Electronic Calculators: The invention of electronic calculators marked a significant advancement. In the 1960s, several companies, including Texas Instruments, Sharp, and Casio, developed electronic calculators that used integrated circuits to perform calculations. These calculators were smaller, faster, and more versatile than their mechanical predecessors.
It is important to note that the development of calculators was a collective effort involving multiple inventors and innovators over centuries. The specific credit for inventing the calculator cannot be attributed to a single individual, as it was a result of continuous improvements and refinements made by numerous contributors.
Types of calculators?
There are several types of calculators available, each designed to serve specific purposes. Here are some common types of calculators:
