Why Is Alfred Harrison Joy Influential?

(Suggest an Edit or Addition)

According to Wikipedia, Alfred Harrison Joy was an astronomer best known for his work on stellar distances, the radial motion of stars, and variable stars. A crater on the Moon has been named in his honor. Early years He was born in Greenville, Illinois, the son of F.P. Joy, a prominent clothing merchant in Greenville and one-time mayor of the town. He received a BA from Greenville College in 1903 and an MA from Oberlin College the next year.
