Ada & Grace: Practical Visionaries
Imagine a computer programmer who still programs in bits and bytes and has never heard of the terms "bug" or "de-bugging." Then, stretch your mind much further, and try to imagine a world without computers. Most of us, no matter what age, don't have such powerful imaginations. But without the contributions of women like Admiral Grace Murray Hopper, who developed the first compiler, and Lady Augusta Ada Byron Lovelace, who made the idea of an Analytical Engine accessible to a world without computers, our most advanced computing device for general use would very likely still be a simple calculator.
Lovelace and Hopper are by no means the only women who have made invaluable contributions to the field of computer science. Without Betty Holberton, who "devised the first sort-merge generator, for UNIVAC I" (AWC, "Frances..."), Grace Hopper would never have been able to design the first compiler. A more contemporary scientist, Dr. Anita Borg, has profoundly influenced the field by "designing and building a fault tolerant UNIX-based operating system" ("Short Biography of Anita Borg"), as well as developing a performance analysis method for high-speed memory systems. However, I've chosen to focus on Lovelace and Hopper because they are probably the most frequently mentioned women in computer science, and they represent two critical historical moments in the field: Lovelace helps to bring the first computer into being, while Hopper forges the start of the modern computer age.
A researcher looking into women and computer science will find Ada's and Grace's names scattered all over the place. Lovelace has a programming language named after her (Ada), the Association for Women in Computing offer the ...

Mathematician Katherine Coleman Johnson was born on August 26, 1918 in White Sulphur Springs, West Virginia to Joylette and Joshua Coleman. Her father was a lumberman, farmer, and handyman. He also worked at the Greenbrier Hotel. Her mother was a former teacher. Ms. Johnson’s nickname was “ the human computer “ At a very early age Ms. Johnson showed a talent for math, she was also anxious to go to school. Her interest was counting. She loved to count it did not matter what it was. She counted the steps to get to church, she counted the number and silverware she washed. Anything that can be counted she counted it. Ms. Katherine was named for the girl who loved to count. Her hobbies was reading book about math, numbers, nasa. If it had something

Grace Hopper, referred to by some as the “Queen of Code,” was one of the first to program the first computers in the 40s and 50s. During World War II, Hopper left a teaching job at Vassar College to join the Navy Reserve. That's when she went to Harvard to work on the first programmable computer in the United States: the Mark I. The Mark I was the first digital computer to be programmed sequentially. Thus, Hopper experienced firsthand the complexities and frustration that have always been the hallmark of the programming field. The exacting code of machine language could be easily misread or incorrectly written. To reduce the number of programming errors, Hopper and her colleagues collected programs that were free of error and generated a catalogue of subroutines that could be used to develop new programs. By this time, the Mark II had been built. Aiken's team used the two computers side by side, effectively achieving an early instance of multiprocessing. Hopper's association with UNIVAC resulted in several important advances in the field of programming. Still aware of the constant problems caused by programming errors, Hopper developed an innovative program that would translate the programmer's language into machine language. This first compiler, called "A-O, " allowed the programmer to write in a higher-level symbolic language, without having to worry about the tedious binary language of endless numbers that were needed to communicate with the machine itself. Hopper died

Although her work was recognized during her time it was in 1953 when it gained wider recognition after being published in B.V. Bowden’s book named, Faster Than Thought: A Symposium on Digital Computing Machines. As computer science flourished in the 1950’s Ada began gaining fans. Ada has often times been called the first computer programmer. Ada was the first to write a machine algorithm for a computing machine which existed only on paper. This was a remarkable task because not only was she a women but she was a women in the 1840’s a time when women were extremely oppressed. Ada was a visionary she showed the understanding of numbers and realized they could be used to represent more than just quantities as put by her “might act upon other things besides number, were objects found whose mutual fundamental relations could be expressed by those of the abstract science of operations… Supposing, for instance, that the fundamental relations of pitched sounds in the science of harmony and of musical composition were susceptible of [mathematical] expression and adaptations, the engine might compose elaborate and scientific pieces of music of any degree of complexity or extent.”(Klein, 2015). She also realized that a machine that manipulated numbers might also be used to manipulate data represented by numbers. Not only was Ada the founder of
In a world of men, for men, and made by men, there were a lucky few women who could stand up and be noticed. In the early nineteenth century, Lovelace Augusta Byron King, Countess of Lovelace, made her mark among the world of men that has influenced even today’s world. She was the “Enchantress of Numbers” and the “Mother of Computer Programming.” The world of computers began with the futuristic knowledge of one Charles Babbage and one Lady Lovelace, who appeared to know more about Babbage’s Analytical Engine than he himself knew. At the time of Lovelace’s discoveries, women were only just beginning to take part in the scientific world, and her love of mathematics drove her straight into the world of men. Her upbringing, her search for more knowledge, her love of mathematics, and her inherited writing abilities brought to life what we know today as computer programming or computer science.

These statistics are amazing, but even more amazing is the development of computers. Now in 2005, in this short 68-year period, computer technology has changed its entire look; now, we use computer chips instead of vacuum tubes and circuit board instead of wires. The changes in size and speed are probably the biggest. When we look at computers today, it is very hard to imagine computers 60 years ago were such big, heavy monsters.
The history of the computer dates back all the way to the prehistoric times. The first step towards the development of the computer, the abacus, was developed in Babylonia in 500 B.C. and functioned as a simple counting tool. It was not until thousands of years later that the first calculator was produced. In 1623, the first mechanical calculator was invented by Wilhelm Schikard, the “Calculating Clock,” as it was often referred to as, “performed it’s operations by wheels, which worked similar to a car’s odometer” (Evolution, 1). Still, there had not yet been anything invented that could even be characterized as a computer. Finally, in 1625 the slide rule was created becoming “the first analog computer of the modern ages” (Evolution, 1). One of the biggest breakthroughs came from by Blaise Pascal in 1642, who invented a mechanical calculator whose main function was adding and subtracting numbers. Years later, Gottfried Leibnez improved Pascal’s model by allowing it to also perform such operations as multiplying, dividing, taking the square root.
Since the beginning of time, humans have thought and made many inventions. Repeatedly the newer one is better than the older. Our minds have created many remarkable things, however the best invention we ever created is the computer. computers are constantly growing and becoming better every day. Every day computers are capable of doing new things. Even though computers have helped us a lot in our daily lives, many jobs have been lost because of it, now the computer can do all of the things a man can do in seconds! Everything in the world relies on computers and if a universal threat happens in which all computers just malfunction then we are doomed. Computers need to be programmed to be able to work or else it would just be a useless chunk of metal. And we humans need tools to be able to live; we program the computer and it could do a lot of necessary functions that have to be done. It is like a mutual effect between us and he computer (s01821169 1).
The computer evolution has been an amazing one. There have been astonishing achievements in the computer industry, which dates back almost 2000 years. The earliest existence of the computer dates back to the first century, but the electronic computer has only been around for over a half-century. Throughout the last 40 years computers have changed drastically. They have greatly impacted the American lifestyle. A computer can be found in nearly every business and one out of every two households (Hall, 156). Our Society relies critically on computers for almost all of their daily operations and processes. Only once in a lifetime will a new invention like the computer come about.
