If you're talking about John L. Holland, the theorist of the Holland Codes of Vocational Personalities and Environments, I believe that would be Omaha, NE.
John P. Holland, an Irish engineer, is credited with developing the first practical modern submarine. He launched the Holland VI in 1897, which was the first submarine to be commissioned by the U.S. Navy in 1900. Holland's designs laid the foundation for future submarine technology.
He invented the submarine, something like an underwater boat, if you don't know what it is. John Philip Holland developed the first submarine to be formally commissioned by the U.S. Navy, and the first Royal Navy submarine, the Holland.
