Annie Jump Cannon!
She was a human computer
at the Harvard College Observatory
classifying stellar spectra
she was the world's leading expert!
She created the spectral class system
we all love and use today!
Oh be a fine girl kiss me right now sweetie!
(O B A F G K M R S)
(repeat)
She classified over 500,000 spectra in her lifetime.
She could do three in a minute!
