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."
