Winona Lake was once home to the world's largest Bible conference. Before 1834, it was the home of the Pottwatomi Tribe, and later it became Spring Fountain Park on Eagle Lake. In 1895, Sol Dickeys's vision of "a kind of Christian Chautauqua" quickly grew in popularity and scope. The many attractions of Winona drew an average of 250,000 visitors each summer. It became so well known, a person could mail letters from anywhere using only the address of Winona Lake--and it would arrive there. Winona Lake has been the home of Billy Sunday and Homer Rodeheaver and the headquarters of the Free Methodist Church, the Grace Brethren Church, and Grace College and Seminary. Billy Graham had an early beginning in the Rainbow Room at the Westminster Hotel. Will Rogers, Helen Keller, John Philip Sousa, Galli Curci, and Ernestine Schumann-Henk are among those who have made appearances at Winona.
