Born in New York City in 1906, she was a curious child who took apart objects to understand their workings. Her supportive parents, particularly her father, ensured she received a quality education. Hopper graduated from Vassar with a degree in math and physics and later earned a Ph.D. in math from Yale, a significant achievement for her time. She began her career as a mathematics teacher, encouraging her students to explain math concepts in words, a practice she continued throughout her life. During World War II, Hopper joined the U.S. Navy and worked on the Harvard Mark 1, one of the earliest digital computers. She documented its operation in a 500-page manual, effectively creating the world's first computer programming manual. Hopper also coined the term 'debugging' after physically removing a moth from the computer, marking the first recorded computer bug. Her work on compilers and high-level programming languages revolutionized how humans interact with computers, making it more intuitive and less reliant on numerical codes.
🌟 Grace Hopper: Visionary and Educator
Grace Hopper was not only a pioneer in computer programming but also a visionary who foresaw a future where everyone could use and program computers. Recognized as the first programmer in the modern sense and a significant figure in the history of computing, Hopper's contributions extended beyond her technical achievements. She believed in the democratization of computer use and programming, advocating for accessibility in technology.

Transcripts
throughout history
there have been a lot of queens queens
of countries queens of music
but there is only one queen of code and
that is grace hopper
popper invented the first compiler
pioneered programming languages
and she was one of the first programmers
of one of the earliest digital computers
oh and she was a u.s navy rear admiral
probably the most dangerous phrase you
can ever use in a computer environment
is that dreadful one
but we've always done it that way hopper
was born in new york city in 1906.
as a child she was known to take things
apart to see how they worked
she had the support of her parents her
father
especially who even way back then
understood the importance that his
daughters had the same education
that his son was going to have so she
went to college
she went on to graduate from vassar with
a degree in math and physics
then she went to yale and earned a phd
in math
which was a rare achievement at the time
after graduation
hopper began a career as a college
mathematics teacher
going against the mold she pushed her
students to not just perform
calculations
but to explain math using words the
tendency of translating mathematical
equations
into ordinary english would accompany
her for the rest of her life
after teaching maths for nearly a decade
grace was ready for something more
she took time off work to study with the
noted mathematician richard coront
shortly after the second great war began
and we were the leading example of that
free world that hitler was committed
to breaking asunder at the age of 36 she
quit her teaching position
divorced her husband and joined the
naval army
with the war in full swing the military
commandeered a lot of technology
to crack enemy communications or help
the war efforts
among those was the harvard mark 1 which
hopper was assigned to work with
mach 1 was all 51 feet long 8 feet high
8 feet deep had all of 72 words in it
could do three editions every second
seems pitiful today
because put about five six ten mark ones
on one chip
until the 1950s there were only maybe
half a dozen
electronic computers in the world the
point is for
all you young people is that
until about 40 years ago nobody would
have known much about computers
she had to translate real world problems
into mathematical equations
and then translate those equations into
commands the computer could understand
how did you know so much about computers
then i didn't
how did the first one yeah uh also
working on the harvard mark 1
was howard aiken who was the mastermind
behind the computer
however he wasn't a fan of having a
woman among his officers
still at one point he gave hopper the
task of documenting how to work with the
harvard mark one
she took her task very seriously writing
a 500 page tome which can be seen as the
world's first
computer programming manual after that
it can soon made hopper his primary
programmer
and top deputy oh and fun fact
during this time hopper coined and
popularized the use of the term
debugging in relation to computing
mark ii stopped we finally located the
failing relay it was one of the big
signal relays
and inside the relay beaten to death by
the relay contacts was a moth about this
big
so the operator got a pair of tweezers
and very carefully fished the moth out
of the relay
put it in the log book put scotch tape
over it
and below it he wrote first actual bug
found
in 1949 hopper again changed her career
she entered the corporate world joining
the team developing the univac one
sweet which would become yet another
historically important computer
around this time she started working on
what is considered the world's first
compiler
a compiler is used to translate
high-level programming languages
into binary language that can be
understood by a computer
programs were being created numerically
with ones and zeros the the operation
codes and she said this is not how we
think as human beings we need to
uh be able to uh tell computers what to
do with our words
opera succeeded with this new concept in
1952
but according to her people were so
skeptical that they wouldn't even touch
it at first
over these years i've had a lot to do
with computers
i've driven a large number of people at
least partially nuts
after all insisting on talking to
computers in plain english was a totally
ridiculous idea and you couldn't do that
except it worked on top of the compiler
hopper and her team released some of the
first compiler-based programming
languages
including flomatic would be pivotal in
the creation of cobalt
the popular language for data processors
you're known as the queen of software
is that right
grace was unapologetic
she was fierce and she was brilliant
everybody regards her as the first
programmer in the modern sense and also
the first woman who in the united states
certainly who was really significant in
the history of
computing she saw even then that someday
that
everyone will be able to use computers
everyone will be able to interact with
them and
she believed that everyone should be
able to to program them
opera continued her work with computers
while steadily growing in rank in the
navy
until she became rear admiral after she
retired
she kept on teaching and giving lectures
until her death in 1992
and despite her many technical
accomplishments in life she said that
her greatest joy
came from teaching yeah
