In September 1965, LIFE magazine profiled a man named Bill Horan, a World War II vet who spent his days yelling at young women. That’s not all he did, though. He also instilled the sort of character traits one might expect from a former paratrooper — tenacity, discipline, resilience — through cheerleading clinics he ran for three decades as a kind of pep-squad drill sergeant.
“Like jacks-in-the-box the girls fly into the air as the hard-eyed man shakes his fist,” LIFE wrote of a typical scene at one of Horan’s clinics.
One last note: That lede in the LIFE article — “Like jacks-in-the-box the girls fly into the air as the hard-eyed man shakes his fist” — sounds like the opening line of a long-lost Wallace Stevens poem. Something with a title like Punching Judy in the Rag and Bone Shop, or Cerberus Slumbers at Edwin Hubble’s Feet. At any rate, it’s especially wonderful when read aloud. Go ahead. Try it.
