William Alexander Holshouser, one of the twelve original founders of the St. Petersburg Board of Trade, serves as its first president.

He was an enthusiastic advocate of promoting patent medicines and advertising the benefits of living in his beloved Tampa Bay town. The gist of his message was that the Pinellas Peninsula was indeed exactly what Dr. Van Bibber, a late nineteenth-century physician, had claimed it to be: “the healthiest place in the country.” His message was spread around the country through postcards and leaflets that his own customers mailed to friends up North. He also printed thousands of booklets and came up with clever schemes to further publicize his beloved city.
