Achievements: discovered what is known as the period-luminosity relationship, which allowed astronomers to measure the distance to specific stars based on the way their light pulses; had progressive hearing loss as a result of an illness she had at 17

She gave us the tools necessary to map out the stars in the universe, the period-luminosity relationship which allowed astronomers to measure the distances to stars

She was almost totally deaf due to an illness contracted after graduating from college

She gave us Leavitt's Law which relates the luminosity of a Cepheid to its pulsation period

Edwin Hubble used her discoveries to establish that the universe is expanding
