Luis Miranda (Courtesy of HBO) New York — Lin-Manuel Miranda, creator of the smash hit musical "Hamilton," is practically a household name. And as a theater enthusiast who has long admired his work, I've had a peripheral knowledge of his father, Luis. It's hard to watch any interview with Lin without detecting his father's influence on him and, very often, Luis is seen in the background cheering on his son. Now, the release of a new HBO documentary, "Siempre, Luis," puts the father center stage. Long before his son was in the spotlight, Luis Miranda made a name for himself as a fixture in New York's state politics, first cutting his teeth in the 1980s working for Mayor Ed Koch. He has since gone on to advise Sen. Chuck Schumer, Hillary Clinton and a host of other political luminaries.
