Orlando Ferguson (November 6, 1846 – February 3, 1911) was a South Dakota resident best known today for a detailed flat earth map he created in 1893.
[2][3] In 2011, Ferguson was the subject of press attention after a copy of his 1893 flat earth map was donated to and accepted by the Library of Congress.
The Fall River Pioneer Museum in Hot Springs also retains a slightly-incomplete copy.
More specifically, his map depicts a "square and stationary" Earth, based on his literal interpretation of the Bible, which references angels visiting the "four corners" of the world.
[4][1] He lectured in Hot Springs on his ideas in 1891, followed up by a 60-page pamphlet full of related hypotheses.
