There are two pieces to the Irving Hart collection in the Grinnell College Archives. One is a letter that Elizabeth Kelsey (Class of 1898) wrote to Hart in April 1898 as he was leaving Grinnell to serve in the Spanish–American War, and the other is an autograph album with signatures of students and faculty from the 1870s when Irving’s mother, Elizabeth Biggar Hart, was a student.
