American royalty is an odd lot. We have “Camelot” and the court of JFK, and we’ve seen the Flivver King (Henry Ford), the Mattress King (from the TV series “Friends”) and the King of the Road (courtesy of Roger Miller). We’ve also had Queen Latifah and Prince. Americans seem to have an odd need for royalty—just witness the lavish attention so many Americans pay to British royalty—but in our own country our de facto royalty seem to be celebrities and the incredibly wealthy. “Commodore” Cornelius Vanderbilt was American royalty and so is Kanye West. Sometimes our American royalty leave odd legacies. One descendent of Vanderbilt is news anchor Anderson Cooper. And we’ll get to meet another American royal and his still-enduring legacy.
