Edward Leedskalnin (Latvian: Edvards Liedskalniņš) (January 12, 1887, Stāmeriena parish, Livonia; December 7, 1951, Miami) was an eccentric Latvian emigrant to the United States and amateur sculptor who single-handedly built the monument known as Coral Castle in Florida. He was also known for his unusual theories on magnetism.

(1887 - 1951) Edward Leedskalnin was born January 12, 1887, according to World War I draft registration records, in Stāmeriena parish, Latvia. Little is known of his childhood, aside from the fact that he was not wealthy and achieved only a fourth-grade education. However Edward was a sickly boy, and often spent his time inside reading books - eventually leading him to discontinue his schooling as it "bored him". For Ed, his development of a yearning to obtain knowledge became a passionate and potent driving force in many endeavours throughout his later life. At the age of 26, he was engaged to marry Agnes Scuffs, a girl ten years younger. However, the girl that Leedskalnin referred to as his "Sweet Sixteen" broke the engagement the night before their wedding.

Richard Buckminster "Bucky" Fuller (July 12, 1895 – July 1, 1983) was an American systems theorist, architect, engineer, author, designer, inventor, and futurist.

Fuller published more than 30 books, inventing and popularizing terms such as "Spaceship Earth", ephemeralization, and synergetic. He also developed numerous inventions, mainly architectural designs, the best known of which is the geodesic dome. Carbon molecules known as fullerenes were later named by scientists for their resemblance to geodesic spheres.

Fuller was born on July 12, 1895, in Milton, Massachusetts, the son of Richard Buckminster Fuller and Caroline Wolcott Andrews, and also the grandnephew of the American Transcendentalist Margaret Fuller. He attended Froebelian Kindergarten. Spending much of his youth on Bear Island, in Penobscot Bay off the coast of Maine, he had trouble with geometry, being unable to understand the abstraction necessary to imagine that a chalk dot on the blackboard represented a mathematical point, or that an imperfectly drawn line with an arrow on the end was meant to stretch off to infinity. He often made items from materials he brought home from the woods, and sometimes made his own tools. He experimented with designing a new apparatus for human propulsion of small boats.
