phoenicia.org published recently an article about the father of the atomic theory. Here are an excerpt…
Mochus the Phoenician was a man from Sidon, Phoenicia. Nothing is known about his life, other than his having flourished before the Trojan Wars. The name Mochus may come from two root words. The first is “msha” in Phoenician (Msha or Mshaa3 – مشاع in Lebanese today means an unattended, uncleared land) and the second is “asya” (or ashya) in Aramaic and it means the hard uneven land.

More: According to Robert Boyle, the father of modern chemistry, “‘Learned men attribute the devising of the atomical hypothesis to one Moschus a Phenician”. Isaac Newton, Isaac Causabon, John Selden, Johannes Arcerius, Henry More, and Ralph Cudworth also credit Mochus of Sidon as the author of the atomic theory. Wikipedia.com
