We’re all in a tizzy here at Radiolab on account of our 20-year anniversary. And, as one does upon passing a milestone, we’ve been looking back in all kinds of ways. Two weeks ago, we went out over the airwaves, “Live on your FM dial,” a callback to our origins as a radio show. We revamped our logo and redid our website (get your Freq on, people!). More recently, Lulu's and Latif’s first stories came up in a meeting. They weren’t always the intrepid hosts of our collective journey in wonder. Soren Wheeler, our editor, thought it would be fun to highlight those firsts for you.  So here they are, baby Latif and Lulu, doing their darndest to make audio magic.
