John Rogan (February 12, 1867 – September 11, 1905; some sources indicate 1871 as his birth year),[1] was an American sharecropper who was recorded as the tallest non-mobile person ever, and the second-tallest person ever at 8 feet 9 inches (267 cm), behind Robert Wadlow.

Although unable to perform physical labor due to his condition, Rogan made a living by selling portraits and postcards at a train station.

He used a goat-pulled cart like a wheelchair and was always the center of attention, often noted for his deep voice and playful attitude.

[citation needed] Rogan died on September 11, 1905, due to complications related to his condition.

A newspaper article reported that his maternal grandfather was also a giant, requiring a larger saddle when he rode horses, hinting at a possible genetic inheritance.
