Henrietta Swan Leavitt
She discovered the period-luminosity relationship for Cepheid variable stars, a crucial tool for measuring cosmic distances.
Most quoted
"A straight line can readily be drawn among each of the two series of points corresponding to maxima and minima, thus showing that there is a simple relation between the brightness of the variables and their periods."
— from Harvard College Observatory Circular 173, 1912
"Since the variables are probably at nearly the same distance from the Earth, their periods are apparently associated with their actual emission of light, as determined by their mass, density, and surface brightness."
— from Harvard College Observatory Circular No. 173, 1912
"The universe is not merely a collection of stars and nebulae; it is a grand narrative, a cosmic poem written in thelight of distant suns, and we, with our telescopes, are learning to read its verses."

All quotes by Henrietta Swan Leavitt (411)
My eyes ache, but my mind is alight with the possibilities.
It is a grand universe, and we are but scratching the surface.
Sometimes I feel like a mere cog in a great machine, but a necessary one.
The stars hold secrets, and I am determined to unlock them.
I wish I had more time for my own research, but the plates call.
The beauty of the night sky never ceases to amaze me.
Every variable star tells a story, if only we learn to listen.
My deafness is a challenge, but it also allows for intense focus.
I hope my work will contribute to a greater understanding of the cosmos.
The patterns are there, waiting to be discovered.
It is a privilege to work among such brilliant minds, even if I am often overlooked.
The universe is far grander than we can ever imagine.
I find solace in the predictability of the stars, even amidst life's uncertainties.
My heart aches for knowledge, for understanding.
The photographic plates are my window to the heavens.
I believe there is a fundamental order to the universe, and we are slowly uncovering it.
The quiet hours spent with the plates are my most cherished.
I often wonder if anyone will remember my name, or just my discoveries.
The work is demanding, but the rewards are immeasurable.
Each dot on the plate represents a distant sun, a story untold.
