Biography
John Middendorf designed the A5 haul bag and the Big Wall ledge, equipment that became standard on vertical expeditions worldwide. In the 1980s and '90s, he climbed first ascents on big walls from Antarctica's Mount Scott to Pakistan's Nameless Tower. He wrote detailed diagrams and essays that translated the craft of living on a cliff face into a shared technical language. His engineering background shaped every piece of gear he produced.
Baby Boomers
1946–1964
The largest generation in history at the time. Shaped by postwar prosperity, the Vietnam War, the sexual revolution, and Watergate. They questioned every institution their parents built — then ran them.
John was born in 1959, placing them squarely in the Baby Boomers. The events that shaped this generation — postwar prosperity, civil rights, Vietnam, and the counterculture — shaped the world they entered and the choices available to them.
