Greek philosopher Aristotle (384–322 BCE) presented the first convincing proofs that the Earth was round, including the observation that Earth’s shadow upon the Moon during a lunar eclipse was curved. Despite this, a small number of people today maintain that the Earth is flat. The Flat Earth Society was founded in 1956 by Samuel Shelton (UK). Between 1971 and 1995 its membership reached around 3,000 members. With the death of its president, Charles Johnson (USA) in 2001, the society effectively closed but was re-formed in 2004. Its current membership is around 300 people.
