"John Krubsack was an American banker and farmer from Embarrass, Wisconsin. He shaped and grafted the first known grown chair, harvesting it in 1914. He lived from 1858 to 1941. He had studied tree grafting and become a skilled found-wood furniture crafter. The idea first came to him to grow his own chair during a weekend wood-hunting excursion with his son.
He started box elder seeds in 1903, selecting and planting either 28 or 32 of the saplings in a carefully designed pattern in the spring of 1907. In the spring of 1908, the trees had grown to six feet tall and he began training them along a trellis, grafting the branches at critical points to form the parts of his chair. In 1913, he cut all the trees except those forming the legs, which he left to grow and increase in diameter for another year, before harvesting and drying the chair in 1914; eleven years after he started the box elder seeds. Dubbed The Chair that Lived; it is the only known tree shaping that John Krubsack did. The chair is on permanent display in a Plexiglas case at the entrance of Noritage Furniture; the furniture manufacturing business now owned by Krubsack's descendants, Steve and Dennis Krubsack."
"[...] In a tiny corner of western Poland a forest of about 400 pine trees grow with a 90 degree bend at the base of their trunks - all bent northward. Surrounded by a larger forest of straight growing pine trees this collection of curved trees, or 'Crooked Forest,' is a mystery.
Planted around 1930, the trees managed to grow for seven to 10 years before getting held down, in what is understood to have been human mechanical intervention. Though why exactly the original tree farmers wanted so many crooked trees is unknown."

"The living bridges of Cherrapunji, India are made from the roots of the Ficus elastica tree. This tree produces a series of secondary roots from higher up its trunk and can comfortably perch atop huge boulders along the riverbanks, or even in the middle of the rivers themselves. [...]
Cherrapunji is credited with being the wettest place on earth, and The War-Khasis, a tribe in Meghalaya, long ago noticed this tree and saw in its powerful roots an opportunity to easily cross the area's many rivers. Now, whenever and wherever the need arises, they simply grow their bridges."
