Demand is the most fundamental driving force of innovation, but the realization of scientific and technological progress comes from people’s unremitting efforts. Today’s society is the Internet society, we can’t live without the Internet, but when it comes to the people who created this Internet feast,

Who do you think of?

Is it Bill Gates who has charmed millions of people? Or jobs, who is still regarded as a myth? No matter who IT is, people seem to think that the CROWN of IT belongs to men.

However, no!

Since the development of IT technology so far, too many women have left a brilliant figure. I’m going to introduce 10 of the most influential people in IT

Women’s elite

Besty Ross for personal computers

As a colleague of Mr Jobs, she designed many of the interface elements, such as command ICONS, that are now embedded in apple’s bones.

She also designed apple’s famous Happy Mac icon to make users feel happier when they boot up. The trash can icon vividly lets the user understand the location of the discarded files. These vivid icon designs greatly arouse the emotions of users and increase their love for Apple products.

If Mr. Jobs has made Apple’s products more approachable, Mr. Kare deserves much of the credit.

Kare’s designs are not unique to Apple products. After Jobs left Apple in the mid-1980s, Kare joined Microsoft, where she used her design prowess to humanize Windows 3.0.

Of course, Kare’s designs don’t stop at Apple and Microsoft. We can see a lot of her designs in Facebook’s e-gift, like the friendly rubber duck. Her latest product is Glam Media, a website where she is co-founder and creative director.

Kare now runs her own digital design company in San Francisco (Kare.com) and sells her designs online at Kareprints.com.

Frequency hopping

Lamarr and her co-inventor, George Antheil, first proposed the technology to help the Navy achieve remote control of torpedoes. The core value of fH technology is that it can freely adjust the channel, thus making it difficult for other users to obtain the signal content. This also makes frequency hopping an early form of encryption.

The two of them were awarded the concept of frequency hopping Technology by American Heritage of Invention & Technology on August 11, 1942. But despite a huge lobbying and fundraising effort, the Navy ultimately didn’t adopt their idea.

Their fh technology finally gained renewed attention in the late 1950s, when engineers at Sylvania Electronic Systems reused it, and the Lamarr concept eventually found its way into military communications security.

Lamarr’s broadband work also has significant reuse in modern wireless technologies such as Bluetooth, wireless networking, and code division Multiple Access (CDMA).

Although her broadband technology initially received a lackluster response, in 1997, three years before Lamarr died, the IT community recognized Lamarr with a special Pioneer Award from the Electronic Frontier Foundation in recognition of her outstanding achievements.

Even though Lamarr is dead, she is still alive, living in the world of wireless technology and his son’s ongoing efforts.

Anthony Loder, her son, recently spoke to CBS News about her talent for scientific invention, which is the subject of Pulitzer Prize-winning author Richard Rhodes’s latest book, Hedy’s Folly:

“She is such an innovative person and never stops looking for solutions. If you ask her a problem, she’ll find a solution.”

As the inventor of some of the early English programming languages, Lieutenant Commander Grace is known by some as the Queen of Software. She is also known as COBOL Grandmother. Grace is best known for her 1958 invention of flow-Matic, which evolved into the common business-oriented programming language (COBOL).

Before Grace invented language-based programming, programmers had to write programs in binary code alone. There is no doubt that this is inhumane. Hopper insists that if everyone could understand programming languages, there would be more programmers.

No doubt she was right.

Although COBOL is not the cutting edge programming technology these days, it still has many honest followers. In fact, in the most recent World Computer survey, 53 percent of organizations said they would still use COBOL to build new business applications.

Grace spent many years traveling the country, visiting schools and military bases, and lecturing on the history of computers and programming languages. She talks fondly about her time with David Letterman in 1986 and loves to talk about her time with the first computer, Mark I.

Hopper died in 1992 at the age of 85.

Ada Lovelace is unique in that she created computer algorithms before computers existed, thus establishing her as the world’s first computer programmer.

Born in 1815 to an Aristocratic English family, Lovelace devoted himself in 1843 to compiling documents for an unfinished “computer”, an analytical machine developed by Charles Babbage, a British mathematician, inventor and mechanical engineer. Between 1842 and 1843, she translated the French documents of The Italian mathematician Luigi Menabrea into English, adding many annotations, including the world’s first computer program.

Although Charles Babbage’s analytical engine did not achieve its intended goal of performing calculations on Bernoulli numbers because of insufficient funding, Lovelace undoubtedly saw potential beyond the simple mathematics of computer computation.

Lovelace wrote in his overview of the analytical engine:

“Many people who are not familiar with mathematics believe that because the analytical machine ultimately provides results in the form of numerical symbols, the process of dealing with numbers must be equations and numbers rather than algebra and analysis. This is not true. The processing of the analytical machine can arrange and combine values like letters or other ordinary symbols. In fact, the results are presented numerically only for regulatory reasons.”

Lovelace died of cervical cancer in 1852 at the age of 36.

Her work was largely underestimated for many years, but she is now honored each year on Ada Lovelace Day with an object-oriented editing language named after her.

Honara Smith, her fourth descendant, is now following in her footsteps in mathematics and computer science, focusing on operations.

Mary Lou Jepsen believes that the screen is the gateway to all the energy contained in the computer.

In 1995 she co-founded and served as chief Technology Officer of MicroDisplay, a company focused on manufacturing small displays. Later, she ran a presentation division at Intel. But then she left after she came up with a bold idea — a computer for every child.

As the founder of One Computer per Child, a nonprofit organization whose mission is to provide affordable, environmentally friendly laptops to children around the world, Jepsen has focused his efforts on developing the XO’s technology, a laptop that uses the least energy and costs the least. The product has already been launched at the United Nations, and Jepsen has already won support from major manufacturers for mass production.

Jepsen left PLC in 2008 to run Pixel Qi, a for-profit organisation. Pixel Qi takes advantage of many of the advanced technologies in the XO, and has begun to introduce terminal products that use Jepsen’s display.

Jepsen said in a recent interview with BizTech magazine:

“With the product we announced today, we have achieved our goal of reducing screen power consumption by a factor of 10 and intend to reduce power consumption by another factor of 10 with our new structure. We’ve released 3 million products that are truly readable in direct sunlight, and we’re the first company to truly achieve such amazing energy savings through new uses of existing machines.”

Today, adventure games like “Call of Duty” are not as popular as popular first – and third-view shooters. But there was a time when adventure games were what geeks were talking about. Williams is best known for his adventure game series, “King’s Quest,” which is in its eighth sequel.

Williams is undoubtedly a visionary pioneer in the PC gaming industry.

She and her husband co-founded the company Sierra On-Line (later renamed Sierra Entertainment) and together shaped the history of video games with complex puzzles and detailed storylines.

Williams’ concept can also be found in other types of games. Take fighting games, for example, and you’ll always find a quest mode created by Williams in which participants must fight and win a series of quests.

Williams’ game emphasizes logic and problem solving, but in general, it’s more of an adventure. At the same time, mundane places are often presented in a game-like way in her games, such as turning a check-in into a fun task to collect digital badges.

After 20 years of game development for IBM PCjr, Tandy 1000, The Amiga, Apple II, Sega master systems, and more, Robert Williams retired from the industry in 1999.

She did an interview with Adventure Classic Gaming in 2006 where she talked about her legacy and her perspective. While she is no longer a game designer, Williams makes it clear that game design is one of her greatest achievements in life.

“Aside from being married to my husband and having two sons, I have some of my fondest memories of building adventure games.”

Ethernet technology

This network innovation has had a significant impact on network switch technology, so some people call her the mother of the Internet. But she was a little reluctant to be called that. She told Intel Free Press Story:

“It’s too much, because I don’t think any one person could have created the entire Internet. There are a lot of people, like Al Gore. In fact, the Internet can only be built with the efforts of many people.”

Perlman is currently an Intel employee helping the company improve its networking and security technologies. She recently developed the new mass link ** transparent interconnection technology ** (TRILL, a new standard for data center connectivity that replaces STP, which she invented earlier).

Telephone scheduling

Hoover told the New Jersey Star-Ledger:

“I designed an execution program for too many calls to keep the phone working efficiently and reduce dropped calls. It’s designed to prevent the machine from losing the handshake signal.”

She won the world’s first software patents. Even more impressively, she had just given birth to her second daughter and was throwing herself into her work at the hospital.

Hoover was inducted into the National Inventors Hall of Fame in Akron, Ohio, in 2008 for his work in telephone technology. She retired at the age of 86.

Marissa Mayer, Google’s first female engineer (employee number 20), joined the company in 1999.

Today, as vice president of Location and local services, Mayer is responsible for managing and developing search products such as Google Maps, Local Search, Google Earth, Street View and Latitude. Her talent in user interface design and product vision has helped Google stay ahead of the curve. At 36, she became the youngest member of Google’s executive operating committee. Marissa’s remarkable achievements in this field have become an inspiration to countless women who aspire to work in the tech industry.

As Marissa wrote in The Huffington Post:

“One of the most important things we can do to increase the number of women working in tech is to provide a variety of different types of role models. The stereotype of a computer scientist is going to do a lot of damage to people’s knowledge and understanding of the profession and saying, ‘Yes, this is what I want to be.'”

Mayer continues her work on Google’s local, maps and search products. She was also recently appointed to wal-mart’s board of directors.

As the first woman to earn a PhD in computer science, BarbaraLiskov was a pioneer in the IT industry long ago.

Liskov has several notable achievements: the invention of CLU, a programming language that laid the foundation for object-oriented programming; The invention of Argus, a programming language that supports distributed programs, greatly expanded the use of CLU; And Thor’s invention, an object-oriented database system.

These object-oriented programming achievements have made a fortune for many modern OOP based languages and operating systems, such as Mac OS X, Objective-C, Visual Basic, NET, and Java.

Liskov continued her research at the Massachusetts Institute of Technology at the age of 72. In 2008, she was awarded the Dot Turing Prize, considered by many scholars to be the Nobel Prize of computing. In 2012, she was inducted into the National Inventors Hall of Fame for her contributions to programming languages and system design.
