Freakonomics Radio has released an updated look at the legacy of physicist Richard Feynman, featuring new stories and recordings from his close friend Ralph Leighton. Host Stephen Dubner detailed how Leighton, a retired schoolteacher living near Berkeley, first bonded with the Nobel laureate not over physics, but over "their love of playing the bongos."
The coverage highlights Ralph Leighton's ongoing role as the dedicated keeper of Richard Feynman's quirky legacy. Stephen Dubner recounted a recent visit to the Esalen Institute where Leighton literally chased down the production crew to share a personal artifact, "waving his phone" because "he wanted to send us one more recording" of himself reading a poem written by Feynman.
Ralph Leighton himself took the mic to describe the origins of their famous, obsessive quest to visit the remote Asian region of Tannu Tuva. During one of their regular weekly dinners, Leighton recalled telling Richard Feynman about a geography class he was set to teach, prompting Feynman to challenge him: "If you know every country in the world, what ever happened to Tannu Tuva?"
While Richard Feynman has been gone for decades, Ralph Leighton's active curation ensures that their shared adventures—and Feynman's eccentric genius—remain vivid. As podcasters continue to mine these historical archives, Leighton's voice remains the essential, affectionate bridge to the human side of a scientific icon.
