Jeff Bezos | Smithsonian Magazine’s 2016 American Ingenuity Award Winner for Technology The Princeton-educated Amazon founder, Washington Post owner and new-economy pioneer also helms an innovative spaceflight company, Blue Origin, which he founded in 2000. This year it became the first aerospace manufacturer to launch, land and relaunch a rocket into space—an essential leap toward our extraterrestrial future. Bezos aims to revolutionize travel and work in space by making spaceflight so inexpensive that entrepreneurs will rush to create new businesses that have not even been imagined yet. Blue Origin’s achievement has been described as comparable to the shift from the sail to the steam engine.

Aziz Ansari | Smithsonian Magazine’s 2016 American Ingenuity Award Winner for Performing Arts The actor, comedian and author is being honored for his starring role as Dev Shah in “Master of None,” the Netflix series that he created with Alan Yang. Like the character he plays, Ansari is the son of Indian immigrant parents, and his smart, surprising take on life, love, technology and cultural identity in the United States has helped make the show “the year’s best comedy straight out of the gate,” as the New York Times put it. Among Ansari’s other accomplishments are his unforgettable portrayal of the loopy Tom Haverford on NBC’s “Parks and Recreation,” his best-selling book about dating in the internet age, Modern Romance (co-authored with Eric Klinenberg), and his blockbuster stand-up act that sold out Madison Square Garden.
