How the Dilemma of the Fourth Dimension and a Progressive Teacher Taught Children How To Play
By Ken Zurski
Mathematician Charles Howard Hinton was both equally fascinated and frustrated by the concept of the fourth dimension, also known as the “other dimension,” or the one dimension of time and space that no one had been able to verify or explain. Albert Einstein tried. He deduced in his Theory of Special Relativity that the fourth dimension is “time” and that “time is inseparable from space.” Since then science fiction writers have used the space-time continuum to great dramatic effect in their stories.
But in 1884, while Einstein was still a toddler, it was Hinton who wrote the definitive article on the subject. In “What is the Fourth Dimension?” Hinton explained that the theory behind a fourth dimension was firmly established, but there was no physical evidence to support it. That was the dilemma, he inferred: “If we think of a man as existing in four dimensions, it is hard to prevent ourselves from conceiving him prolonged in an already known dimension.” Hinton used a four-cornered room, or cube, for example, to explain how one can only reach three dimensions. “Space as we know it, is subject to limitation,” he conceded.
However, to teach his children math skills, Hinton built a three-dimensional bamboo dome with evenly spaced geometric shapes. His son, Sebastian, remembers climbing and hanging from the dome while his father called out intersections for the children to identify.
“X2, Y4, Z3, Go!” Hinton would command.
Hinton died unexpectedly in 1907 from a cerebral hemorrhage. While he is mostly remembered for his work on the fourth dimension, in stark contrast, he is also credited with introducing the first pitching machine (for baseball) – more like a gun – called the “mechanical pitcher,” and designed for the Princeton University team. The machine used gunpowder to fire the ball.
But the geometric dome he created for his children also had a lasting effect. Especially on his youngest son Sebastian.
Sebastian ended up marrying a teacher, Carmelita Chase, who grew up in Omaha, Nebraska and moved to Chicago in 1912 to become Jane Adams’ secretary at Hull House. That’s when she met Sebastian, a patent lawyer in town.
Carmelita was pretty, smart, and multi-talented. In college, she excelled in tennis (among other sports), acted in plays and sang in the choir. “She has distinguished herself in athletics as well her studies,” the Chicago Daily Tribune described in announcing the couple’s engagement in 1916. She and Sebastian would eventually have three children.
Shortly after getting married, however, Carmelita put most of her time and efforts into her work. She opened a kindergarten and nursery school at her Chicago apartment which was directly across from a park.
“Frustrated by her own ‘dreary’ school experience, she was determined to create learning environments for her school children and others that would be joyfully experimental,” author Susan Ware wrote about Carmelita in Notable American Women.
The type of teaching she endorsed already had a name: progressive education. For Carmelita, this included incorporating more outdoor activities like hiking, camping, farming and the care of animals to daily activities. “She would come into a room and it would be an explosion,” a former student recalled in the book Founding Mothers and Others, “But it was a happy occasion. She could sweep people up and carry them to Mars.”
In 1920, while watching his wife’s school children playing outside their Winnetka, Illinois home, Sebastian had a revelation. Why not build something they could climb on?
He envisioned a three-dimensional structure similar to his father’s geometric dome, but for play rather than instruction. He reportedly jotted down the idea on a napkin and perfected the plan for a patent submission. Then he built it.
Hinton called it a Jungle Gym.
At the time of its conception, however, the Jungle Gym was never heralded as the important contribution to the children’s playground as it is today. In fact, Hinton’s only recorded words about his invention are attributed to his detailed patent filings: “Children seem to like to climb through the structure and swing their head downward by the knees, calling back and forth to each other. A trick which can only be explained of course by a monkey’s instinct.” While the name Jungle Gym never officially changed, many people began seeing the correlation with the primate’s distinctive behavior and started calling it “monkey bars” instead. The moniker stuck.
Unfortunately, Sebastian Hinton is a figure lost to time. Although he married a socialite in Carmelita, Hinton preferred to stay out of the spotlight. Tragically, just a few years after creating the Jungle Gym, he committed suicide in a clinic after reportedly being treated for depression.
Caremilta chose not to publicly disclose her husband’s illness and cause of death (he hung himself). She packed up the family and moved east. Today, she is best remembered for founding Putney School, an independent progress education institution in Vermont that is still in existence today.
Hinton’s original Jungle Gym is permanently on display in the backyard of the Winnetka Historical Society Museum.

Your first picture is NOT Charles Howard Hinton.
It is Rev. Edwin A. Abbott educator and author of “FLATLAND”

I’m not the only one getting it wrong.
