A famous bearer is American poet Edwin Arlington Robinson (December 22, 1869 – April 6, 1935). He won 3 Pulitzer Prizes for Poetry, for his works "Collected Poems" in 1922, "The Man Who Died Twice" in 1925, and "Tristram" in 1928.
Edwin Powell Hubble (November 20, 1889 – September 28, 1953) was an American astronomer. He profoundly changed astronomers' understanding of the nature of the universe by demonstrating the existence of other galaxies besides the Milky Way. He also discovered that the degree of redshift observed in light coming from a galaxy increased in proportion to the distance of that galaxy from the Milky Way. This became known as Hubble's law, and would help establish that the universe is expanding.
They also named the now famous orbital telescope after him. :)
The name Edwin is also frequently used in The Netherlands, and its pronunciation is the same as it is in English (ED-win). A well-known Dutch bearer of this name is the radio DJ Edwin Evers. [noted -ed]
