Byte Sized Episode 1: Grace Hopper and the Compiler

Summary

In this episode of Bite Size, host Joshi explores the life and achievements of Admiral Grace Hopper, a pioneering computer scientist who invented the compiler and coined the term in 1952. Working at the Eckhardt-Mauchly Computer Corporation on the UNIVAC I computer, Hopper developed the A-0 system, a precursor to compilers that translated mathematical symbols into machine code. Despite initial skepticism from her peers, she persevered, creating the A-1 and A-2 systems, and the Flow-Matic compiler, which laid the groundwork for COBOL. Her work influenced the development of the Lisp language and earned her the Presidential Medal of Freedom. Up next, the series will cover Leonard Euler and the origins of graph theory.

💻 Introduction to Grace Hopper and Compilers

The video introduces Admiral Grace Hopper, a pioneering computer scientist known for her invention of the compiler. A compiler is described as a translator program that converts human-readable code into machine code. Grace Hopper, despite initial skepticism from her colleagues, developed the first compiler as part of the A-0 System while working at the Eckhardt-Mauchly Computer Corporation on the UNIVAC I computer. Her work laid the groundwork for future compilers and programming languages, including the FLOW-MATIC compiler, which influenced the creation of COBOL. The video also touches on her recognition with the Presidential Medal of Freedom and her enduring legacy in computer science.

Keywords

💡Compiler

A compiler is a type of translator program that converts code written in a programming language into machine code that a computer can understand and execute. In the script, the compiler is central to the narrative as it was created by Admiral Grace Hopper. It's described as a 'fancy type of translator program' that helps turn human-readable code into something a computer can read.

💡Grace Hopper

Admiral Grace Hopper was a pioneering computer scientist who is best known for her work on the compiler and for coining the term 'compiler' itself. The script highlights her as a figure of perseverance and innovation, emphasizing her creation of the first compiler and her vision to translate English into machine code.

💡Eckhardt-Mauchly Computer Corporation

The Eckhardt-Mauchly Computer Corporation was an early computer company where Grace Hopper worked. In the script, it's mentioned as the place where she was hired to work on the UNIVAC computer, which was a significant milestone in her career and the development of the compiler.

💡UNIVAC

UNIVAC, short for Universal Automatic Computer, was one of the early commercial computers. The script mentions that Grace Hopper worked on the UNIVAC computer, which was a part of her journey towards creating the compiler.

💡A-0 System

The A-0 System, also known as the Arithmetic Language, was an early programming language developed by Grace Hopper. The script describes it as a system that allowed her to transform mathematical symbols into machine code, which was a precursor to her development of the compiler.

💡A-1 System

The A-1 System was an iteration of Grace Hopper's compiler work, following the A-0 System. The script indicates that Hopper continued to iterate on her compiler, with the A-1 System being one of these developments.

💡A-2 System

The A-2 System was another iteration of Grace Hopper's compiler, building upon the A-0 and A-1 Systems. The script suggests that these iterations were part of her ongoing efforts to refine and improve the compiler's capabilities.

💡FLOW-MATIC

FLOW-MATIC was a compiler developed by Grace Hopper that was a significant step towards high-level programming languages. The script highlights that it was the foundation for one of the 20th century's most popular programming languages, emphasizing its importance in the history of computing.

💡LISP

LISP is a programming language that is mentioned in the script as being influenced by Grace Hopper's compiler work. It was the first language to use an interpreter, which was based on the compiler that Hopper developed.

hello welcome to bite size I'm fighting

Joshi and today I want to tell you

everything about Grace Hopper and her

compiler so first off what's a compiler

well a compiler is like a fancy type of

translator program

they're basically translators that help

turn our code into something that's

readable by the computer and the

compiler was created by someone really

awesome that I loved her name is Admiral

Grace Hopper not only did she create the

compiler she also coined the term

compiler back in 1952 Admiral Grace

Hopper came up with the compiler when

she was working at the Eckhardt

Lockley something computer corporation

she was hired at the time to work on

something called the univac computer the

univac one computer I think and what was

really cool is she was also working on

another thing on the side something

called the a through 0 system and this

was something that was going to allow

her to transform mathematical symbols

into machine code and she actually

pulled it off because she's an admiral

and she's badass there we go and she

turned she successfully was able to turn

mathematical symbols into machine code

and this was basically her first

compiler and she even told her

colleagues about this and guess what

they did not believe her and they just

shot her down

of course typical even though her

colleagues didn't believe her grace

Admiral grace I should say was not

dissuaded she knew that she could do big

things and she had really big dreams she

didn't just want to translate

mathematical symbols into machine code

she eventually wanted to translate the

English language into machine code so

she kept iterating on the A's through a

through zero system and she eventually

came up with two more iterations of that

same compiler the a through one system

and the a through two system she

eventually turned her compiler into

something called the flow-matic compiler

which ended up being the foundation for

the 20th century's most popular language

I know you know what I'm about to say

hobo her compiler led to her doing all

these really cool things including by

the way winning the Presidential Medal

of Freedom which was so cool and she

totally deserved it because she kept

working on this even though people kept

shooting her down and not believing that

her creation and her ideas were gonna be

successful in fact her compiler ended up

being the foundation for the very first

interpreter that was used in the Lisp

language Grace Hopper Admiral Grace

Hopper she made so many huge impacts and

we should all be really grateful in fact

coming up next a quick word from our

sponsors plus a preview of the next

episode of bite sized we hope you

enjoyed the first episode of bite sized

there's a lot more great stuff to come

the first episode was sponsored by deaf

community itself but we're looking for

sponsors for future episodes if you

think your company might be interested

email visit does too and we'll get

started right away thanks a lot and now

onto the next episode and I want to tell

you today about Leonard Euler and the

creation of graph theory so in order to

tell the story we got to go way back to

1735

Wow good job grace

[Laughter]
