The first known work on space colonization was The Brick Moon, a work of fiction published in 1869 by Edward Everett Hale, about an inhabited artificial satellite.
The Russian schoolmaster and physicist Konstantin Tsiolkovsky foresaw elements of the space community in his book Beyond Planet Earth written about 1900. Tsiolkovsky had his space travelers building greenhouses and raising crops in space. Tsiolkovsky believed that going into space would help perfect human beings, leading to immortality and peace.
