According to a newspaper article, the Danville Swimming Pool was to hold its grand opening in Danville Park on Saturday, August 1, 1959 at 10 am. Henry Cox was the pool manager, and membership cards were 25 cents each.
In May 1983, the Danville Town Board voted to rename the swimming pool in Ellis Park to "Gill Pool", in honor of William T. "Billy" Gill, who was the general contractor when it was built and was credited for generally leading the project.
NOTE: Today the pool is known as the Gill Family Aquatic Center.
