In an article by my grandfather, Ray Ewry, he mentions a Jimmy Studebaker. Ray was a student at Purdue from 1890 through 1894 and at the Field Day event on May 22, 1891, he mentions in the article Jimmy Studebaker as the winner of many running and jumping events.
I am in the process of writing a book on Ray Ewry's illustrious career that took him to the Olympics from 1900- 1908 and where he accumulated 10 gold medals.
I would suggest the searchers of Jimmy Studebaker to reference the Purdue e-Archive site and search his name that way. I hope this has been helpful.
I can be reached at my e-mail and can show the article to anyone interested.
