Newman, John B. (L)
John B. Newman, was a 19th century American physician who produced a short volume purporting to demonstrate connections between the Phoenicians, Atlanteans and Native Americans. He was one of the early proponents of a large island stretching across the Atlantic from northwest Africa towards America, providing a stepping stone or landbridge between the Old and New Worlds for animals and man.
It is worth pointing out that it was written in 1849, over thirty years before Ignatius Donnelly published his influential work.
