Life became easier for mathematicians and users of the hand-held electronic calculator with the help of Jerry Merryman with two other men who invented the little contraption that changed computing forever! well, he has died at age 86.
His death was confirmed today to CNN by his wife, Phyllis, She said Merryman died February 27 after a brief illness. He had been hospitalized since late December following complications related to pacemaker surgery.
History has it that, Merryman was a young engineer at Texas Instruments in 1965 when he was put on a team that included fellow engineers Jack Kilby and James Van Tassel. They were tasked with creating a small computing device that could fit in a shirt pocket.
At the time Texas Instruments was looking for a head-turning product to showcase its new integrated circuits, recently invented by Kilby (who would win the Nobel Prize decades later for his efforts).
Kilby, who led the team, told the engineers the device they came up with needed to be about the size of a book, it needed buttons for inputting data, it would have to have some kind of digital display and it would have to run on batteries, according to the journal American Mathematical Monthly.
Later on, “Not yet using the term ‘calculator,’ the group discussed building a slide rule computer. Van Tassel worked primarily with the keyboard, Kilby himself worked on the power source, and Merryman inherited the logic and output,” the journal says.
Soon after, the trio produced a hand-held calculator, called the CAL-TECH. It was about four inches by six inches, featured a paper display instead of a digital one (to save power) and was heavy, weighing almost three pounds. That’s no surprise` because it was made out of an aluminum brick.
“We got a solid brick of aluminum and took a milling machine and hollowed it out,” Merryman told the journal in a 1996 interview.However, it is usually hard to find these systems directly built into the car’s inboard or you can purchase portable devices which are to be installed into https://pdxcommercial.com/order-1873 levitra without prescription the vehicle.

In 1967, the first patent for the calculator was filed.
So to say, It was the first mini-calculator to have the same computing power as the larger machines of the time, which were as big as a typewriter, expensive and had to be plugged into a power source. The small calculators became ubiquitous and for a lot of people they were the first hand-held device they ever owned.
The hand-held calculator prototype that Merryman helped invent was eventually donated by Texas Instruments to the Smithsonian’s National Museum of American History in Washington.
Thenafter, Merryman retired from T.I. in 1994. According to his wife, he received a call from the company the next morning asking him to come back and consult for them, which he did.
She also confirmed her husband was content with his role on the team.
More from her, “He was brilliant, and very much so humble. He always said that he was in the shadow of Jack Kilby, she said.
“Other people would have told you that he was much smarter than anyone. After his retirement, friends were still calling him to ask him questions, because he was the guy with all the answers. We’re now all asking, ‘Who are we going to ask now?'”
Jerry Merryman may have left to the beyond but his legacy remains immortal.
