Multi-degreed, dishy raconteur Glenn de Villiers is a local native who traces his family lineage directly to a key figure in the founding of New Orleans. The city’s history, then, is literally in his DNA. The tall, chapeaued bon vivant is worth following around the French Quarter for his laissez-faire saunter and breezy repartee alone, but his insider perspective can’t be replicated through a library of books. Glenn describes the customs and culture like he’s lived it (he has), and serves up the facts with urbane wit and a generous dollop of gossip. It works best on his Literary and Gay History “Twirl” tours, though the French Quarter and Louisiana History tours are all worthy. Some might find this personal take tiresome. Not us. Added pluses: He maxes his groups at 12 participants and donates profits to worthy local causes.
