Russell Kirsch, inventor of the pixel, dead at 91

Renowned computer scientist Russel Kirsch, best known as the inventor of the digital imaging pixel, died on Tuesday, August 11. 

Kirsch died in his home in Portland, Oregon, from a form of Alzheimer’s disease, according to The Oregonian. He was 91 years old.

Kirsch changed the landscape of digital imaging as we know it with the invention of the pixel by asking, “What would happen if computers could look at pictures?” In 1957, he and his colleagues at the National Bureau of Standards (now known as the National Institute of Standards and Technology) used the first image scanner, the Standards Eastern Automatic Computer, to take a digital photograph of his three-month-old son.

The photograph was a simple black-and-white, 5 x 5 cm square photo with a resolution of 176 by 176 pixels. What would later come to be known as the very first scanned image was included in “100 Photographs that Changed The World” in Life Magazine in 2003.

Because of Kirsch’s digital imaging work, we now have technologies like CAT scans and satellite images. He even has a mathematical algorithm named after him, the Kirsch Operator, which is used to detect edges in images. 

“Everything that I did was in the public domain,” Kirsch told The Oregonian in a 2007 interview. “It’s because of me that Bill Gates is who Bill Gates is now.”

Kirsch is survived by his wife of 65 years, Joan, his four children Walden, Peter, Lindsey, and Kara, and four grandchildren, Nathan, Noah, Gus, and Gabrielle.

It has almost become a custom for Google to debut several exclusive features every time it announces new Pixel smartphones. This year, for example, we saw the company revamp the popular At a Glance option with a host of new feature additions, some of which are already live on the Pixel 6 series. Now, it seems there are more features on the way.

The usually trustworthy folks at 9to5Google recently performed an APK teardown of the beta version of the Android System Intelligence app for the Pixel 6 series. After closely examining the various lines of code within the APK, they were able to deduce that Google intends to soon enhance the At a Glance feature with several new capabilities.

The Google Pixel 6 lineup currently includes the Pixel 6 and the Pixel 6 Pro, both of which are in high demand and are extremely difficult to get a hold of. If you were looking to get either of these phones, you may want to consider dropping the idea entirely. Google is reportedly working on a midrange Pixel 6 series handset called the Pixel 6a, expected to launch in the next few months.

Over the weekend, popular smartphone leaker Steve Hemmerstofer (OnLeaks), in collaboration with tech blog 91Mobiles, released the first-ever renders of what is thought to be the upcoming Pixel 6a. As you might have guessed by now, the Pixel 6a will be a slightly watered-down version of the Pixel 6/6 Pro with more midrange specifications and a much lower asking price.
