John Gummere
John Gummere was an American astronomer and one of the founders of Haverford College in Pennsylvania. He was born in 1784 near Willow Grove, Pennsylvania. His son Samuel James Gummere was the first president of Haverford College, and his grandson Francis Barton Gummere was an influential scholar of folklore and ancient languages and an alumnus of Haverford College.
Gummere built the first observatory at Haverford College, now commemorated by a plaque at its original location, after being replaced by the Strawbridge Observatory in 1850.
