For nearly three decades, Bob Keeshan was a fixture of American children’s morning routines as the star of the CBS program Captain Kangaroo, which ran from 1955 to 1984. “If you were going to build a monument to commercial children’s television and you had to put a statue on top of it, it would have to be Bob Keeshan,” Robert Thompson, director of the Center for the Study of Popular Television at Syracuse University, told the Los Angeles Times in 2004, after Keeshan’s death.

But what did Keeshan do with his life after Captain Kangaroo? As it turns out, he devoted his last years to children as well, through various professional pursuits. And Keeshan’s devotion to one special kid in his life — his grandson Britton — posthumously took the TV personality’s legacy to new heights.
