Event Details

The largest yearly confab of Mensans anywhere, the American Mensa Annual Gathering started as a small, two-day meet-and-greet at the New York Belmont in 1963. The event now spans five days — six in 2021! — and features a sprawl of talks, games, and entertainment unlike any other.

The 2021 Annual Gathering is a party 75 years in the making! Join Mensans from around the world to celebrate the 75th anniversary of Mensa’s founding. With a focus on cultural and intellectual experiences from around the globe, we aim to showcase all the different kinds of smart. Registration opens Oct. 1.

A night to sparkle and shine

Join us for the Annual Gathering Gala Dinner, an entertaining evening filled with food, friends, and special guest speaker Frank Abagnale.

Frank’s story has been told in books, TV shows, and a blockbuster film. His story involves a high-profile FBI manhunt and millions of dollars’ worth of checks conned by Frank as, among other things, a Pan Am pilot and a doctor. You may think you’ve heard the whole story, but you’ll have to find out for yourself. He’s got plenty to say about cybercrime, identity theft, and scams.

Dinner includes a Texas field greens salad and your choice of braised beef short ribs, rosemary Dijon chicken chop, or grilled marinated portabella mushrooms with broccoli and cauliflower gratin.

Dive Into a Deep Sea Dining Adventure

Join us for an immersive, adventurous, and entertaining dining experience at the 2021 World Gathering Welcome Dinner, hosted at Houston’s world-famous Downtown Aquarium. Enjoy views of over 100 species of aquatic life from around the globe as they swim right by your table, including reticulated rays, moray eels, giant groupers that weigh over 250 pounds, shovel-nosed guitarfish, and more!

Non-deep sea entertainment to be announced shortly.

Dinner includes your choice of a surf and turf spread of sirloin and snapper or a tasty vegan bowl of ancient grains, onions, and greens tossed in house-made pesto. For dessert, we’ll have a trio of assorted fruit mousse in chocolate cups. Breads, coffee, and iced tea will be complemented by a cash bar.

Mensa Foundation Colloquium 2021: Advances in Food Science

Before it hits our plates, there’s a lot that goes on behind the scenes with what we eventually eat. The ongoing developments within our food supply are staggering — and that was before the pandemic: gene-edited crops, plant-based proteins, breakthroughs in how we understand nutrition, the consolidation of suppliers, agriculture’s escalating biological arms race, changing climates — it’s enough to make your stomach churn! We will also explore the impact COVID-19 has had on food supplies and safety.

Presented by the Mensa Education and Research Foundation, this one-day educational symposium provides a forum for Mensans and the general public to explore, debate and evaluate a major issue of long-range importance to society.
