John Adelbert Parkhurst

He was born in Dixon, Illinois, and attended the public schools in Marengo, IL and Wheaton College.

He returned to Marengo, Illinois where he kept a small, private observatory that he used primarily for variable star observation.

He remained on the staff for 25 years, later becoming an associate professor at the University of Chicago, specializing in practical astronomy.

On February 27, 1925, he suffered a cerebral hemorrhage and died a few days later at his home in Williams Bay.
