The invention of the electronic calculator revolutionized the way we perform calculations. Before the advent of electronic calculators, people relied on mechanical calculators, which were bulky and time-consuming to use. The electronic calculator, on the other hand, was compact, fast, and accurate, making it an essential tool for professionals and students alike.

The first electronic calculator was invented in the early 1960s by a team of engineers led by Jack Kilby at Texas Instruments. The calculator was based on the newly invented integrated circuit, which allowed for the miniaturization of electronic components. The first electronic calculators were large and expensive, and they were mainly used by scientists and engineers. However, as the technology improved, electronic calculators became smaller, cheaper, and more widely available, eventually replacing mechanical calculators in the late 1970s.

Invention of the First Electronic Calculator

The Calculating Revolution

The invention of the electronic calculator was a significant milestone in the history of computing. It revolutionized the way people performed calculations, making complex mathematics more accessible to the masses. The electronic calculator was the first device to use solid-state technology, which made it smaller, faster, and more reliable than its mechanical counterparts.

Before the invention of electronic calculators, people used mechanical calculators, such as the abacus, slide rule, and adding machine, to perform calculations. These devices were slow, bulky, and prone to errors. The electronic calculator changed all that by introducing a new era of computing that was faster, more accurate, and more efficient.

Key Inventors and Contributions

The invention of the electronic calculator was the result of the efforts of several key inventors and engineers. One of the earliest pioneers of electronic calculators was Jack Kilby, who invented the integrated circuit in 1958. The integrated circuit was a breakthrough in solid-state technology that allowed for the miniaturization of electronic components.

Another key contributor to the development of electronic calculators was the Japanese company Busicom, which produced the first handheld calculator in 1971. The Busicom LE-120A, known as the HANDY, was the first calculator to use a "calculator on a chip" integrated circuit. It featured a 12-digit display in red LED and cost $395 when it first went on sale in January 1971 [1].

Other notable inventors in the field of electronic calculators include Texas Instruments, who produced the first pocket-sized calculator in 1972, and Hewlett-Packard, who introduced the first scientific calculator in 1972. These devices paved the way for the development of more advanced calculators, such as graphing calculators, which are widely used in education and research today.

In conclusion, the invention of the electronic calculator was a significant milestone in the history of computing. It revolutionized the way people performed calculations, making complex mathematics more accessible to the masses. The key inventors and engineers who contributed to the development of electronic calculators paved the way for the development of more advanced computing technologies, which continue to shape our world today.

Technological Advancements Leading to the Invention

Pre-Electronic Calculation Devices

Before the invention of electronic calculators, people used various mechanical devices for calculation purposes. One of the earliest devices was the abacus, which dates back to ancient times. It was used for basic arithmetic operations and was made up of beads or stones on rods. Later on, more advanced mechanical calculators were developed, such as the Pascaline, invented by Blaise Pascal in the 17th century. These calculators used gears and wheels to perform calculations.

Electronic Components Development

The invention of electronic components such as transistors and integrated circuits paved the way for the development of electronic calculators. The first electronic calculator was developed in the 1960s by Bell Punch Co. Ltd. in Britain. It was called ANITA (A New Inspiration To Arithmetic/Accounting) and was the world's first all-electronic desktop calculator. ANITA used vacuum tubes and magnetic drum memory for storage.

In 1967, Texas Instruments introduced the first handheld electronic calculator, the Cal Tech. It was followed by the Sharp QT-8D in 1969, which was the first calculator to use a single integrated circuit. The Busicom LE-120A, known as the HANDY, was the first handheld calculator to use a "calculator on a chip" integrated circuit. It was developed by Busicom and went on sale in January 1971.

The development of electronic components continued to improve the functionality and size of calculators. By the 1980s, scientific calculators were widely available and affordable. Today, calculators are integrated into many electronic devices such as computers, smartphones, and tablets, and are used for a wide range of applications including finance, engineering, and education.

The ANITA Calculator

ANITA's Launch and Features

The ANITA calculator, short for "A New Inspiration To Arithmetic/Accounting", was the world's first all-electronic desktop calculator. It was developed by Control Systems Ltd. in Britain and marketed under its Bell Punch and Sumlock brands. The ANITA was launched in 1961, and it was a groundbreaking milestone in the history of calculators.

The ANITA Mk VII and ANITA Mk VIII calculators were launched simultaneously in late 1961. The ANITA Mk VII was designed for the British market, while the ANITA Mk VIII was designed for the American market. Both models used vacuum tubes and cold-cathode switching tubes in their logic circuits and nixie tubes for their numerical displays.

The ANITA calculator had several features that made it stand out from other calculators of its time. It could perform addition, subtraction, multiplication, and division, and it had a memory function that allowed users to store and recall results. The ANITA also had a printer attachment that could print out results on paper.

Impact on the Market

The ANITA calculator had a significant impact on the calculator market. It was the first calculator to use electronic technology, and it paved the way for the development of more advanced calculators. The ANITA was quickly outdated, but it set the stage for the development of smaller, more powerful calculators that could be used in a variety of settings.

The ANITA calculator was also significant because it was the first calculator to be developed by a British company. The Bell Punch Company, which developed the ANITA, was a manufacturer of ticket punches before it entered the calculator market. The success of the ANITA calculator led to the formation of Sumlock Anita Electronics Ltd., which took over the Bell Punch Company's former activities in the field of calculating machines.

In conclusion, the ANITA calculator was a groundbreaking milestone in the history of calculators. It was the world's first all-electronic desktop calculator, and it had several features that made it stand out from other calculators of its time. The ANITA calculator had a significant impact on the calculator market, and it paved the way for the development of more advanced calculators.
