Biography
Henry Kendall was a man of intense focus, both in the laboratory and on the sheer granite faces of mountains. A professor at MIT for decades, he was a central figure in experiments conducted at the Stanford Linear Accelerator Center in the late 1960s. By firing electrons at protons at unprecedented energies, his team, alongside Jerome Friedman and Richard Taylor, discovered that the particles inside the proton were point-like and free—a revolutionary finding that confirmed the quark model of particle physics. This work earned them the Nobel Prize in 1990. Beyond physics, Kendall was a formidable mountaineer and a deeply committed environmentalist, co-founding the Union of Concerned Scientists to advocate for science in public policy, particularly around nuclear weapons and climate change.
The Greatest Generation
1901–1927
Grew up during the Depression, fought World War II, and built the postwar economic boom. Defined by shared sacrifice, institutional trust, and a belief that hard work and loyalty would be rewarded.
Henry was born in 1926, placing them squarely in The Greatest Generation. The events that shaped this generation — world wars, depression, and rapid industrialization — shaped the world they entered and the choices available to them.
