01Parkhurst voted in the 1868 U.S. presidential election in Santa Cruz County, the first known trans man to do so in America.
02Described by contemporaries as among the finest stagecoach drivers on the California-Oregon run, handling six-horse teams in mountain snow.

Amelio Robles Ávila

Amelio Robles Ávila rode with Emiliano Zapata's forces through the Mexican Revolution, earning the rank of colonel through combat — then lived openly as a man for eight more decades, receiving veterans' recognition from the Mexican government in his nineties.

Dawn Brancheau

Dawn Brancheau, SeaWorld Orlando's most senior trainer, was pulled into the water and killed by orca Tilikum in front of an audience on February 24, 2010. She had 16 years of experience. The show had just ended.

Iamblichus

He rose ten cubits off the ground — glowing gold — while his students watched twice. A Syrian Neoplatonist who made ritual magic philosophically respectable. What do you do with a man who keeps floating?

Katalonia

In July 1936, Barcelona's anarchists collectivized every barbershop, hotel, and tram line within weeks of Franco's coup. Waiters became co-owners. One journalist noted the menu prices hadn't changed, but the waiters walked differently.

Orlan

Orlan had horns surgically implanted into her forehead while reading Kristeva aloud on the operating table. Nine operations. Each broadcast live. The body as an artist's material — edited without anesthesia for the soul.

Casu martzu

Casu martzu is Sardinian pecorino colonized by live cheese fly larvae; the maggots leap up to 15 centimeters when disturbed. EU law bans its sale, so it trades on the black market.

Charley Parkhurst

Charley Parkhurst drove stagecoaches through the Sierra Nevada for decades — one-eyed, weathered, legendarily skilled — and cast a ballot in California in 1868, fifty-two years before women were legally permitted to vote there.
