The British businessman and one of the fathers of modern computing,

Sir Clive Sinclair

, died this Thursday at the age of 81 at his home in London, after suffering a

long illness


It was confirmed by his daughter, Belinda, to

The Guardian


Sinclair was the creator of some of the first personal computers (PCs) that first arrived in homes throughout the 1980s,

with the ZX Spectrum

leading the way as the most remembered by all.

Born in 1940, this British inventor and businessman dedicated his entire life to devising innovative ways to bring

electronics into the home.

One of his greatest successes is the first

pocket calculator

, but his idea of ​​miniaturizing devices resulted in a multitude of products, such as small transistors and portable televisions, as well as watches with LCD technology.

However, it was in the realm of home computing that his many companies found their greatest success.

With the idea of ​​offering

an inexpensive computer for the general public

(in a time when computers were not home but business, huge and very bulky), his company Sinclair Research was responsible for the ZX 80.

Launched in 1980, a tiny device humble in specs, but with an unbeatable price (

less than 100 pounds

) that revolutionized the arrival of computers in homes, especially in Europe.

Soon after other models arrived, such as the ZX81, but it was with the famous ZX Spectrum - designed by Richard Altwasser and Rick Dickinson - and its well-remembered rubber keyboard, that it achieved a milestone in terms of sales and popularity.

They used


to load information, not floppy disks.

Although its main market was the British, the computers produced by Clive Sinclair's company had great success in many other countries, including Spain, where with only

7 colors

and a single sound channel it managed to carve out an important niche.

As its millions of users - the ZX Spectrum estimated to have sold

5 million units

- made their first steps in programming while learning BASIC or loading cassette games, Sinclair kept looking for promising new business horizons.

The first ZX Spectrum had only 16 kbytes of main memory and needed to work in tandem with a mono cassette to load the games and programs stored on the same tapes that music was distributed on at the time Sinclair released the first

version. of his ZX Spectrum in 1982


That computer had only

16 kbytes of main memory

and needed to work in tandem with a monophonic cassette to load the games and programs stored on the same tapes on which music was distributed at the time.

In addition to marketing improved versions of the computer, he also anticipated decades in the mid-1980s to launch the C5, a three-wheeled electric vehicle that was a financial hit for his company.

"He was quite an amazing person. He

was so smart and always interested in everything

. My daughter and son-in-law are engineers, and I used to talk engineering with them," recalled her daughter Belinda when she broke the news.

Clive Sinclair was 81 years old.
