Bonsor, George (Jorge)
George (Jorge) Edward Bonsor (1855-1930) was born in France to British parents but spent most of his life working as an artist and archaeologist in Spain. In the 1920s Bonsor and Adolph Schulten searched in The Doñana Marshes for Tartessos. An account of Bonsor’s work is available online(a), in Spanish, but it translates quite well with Google. Despite comments recently attributed to Professor Richard Freund, [0879.71] I have no evidence that Bonsor equated Tartessos with Atlantis as Schulten did.
A number of his books, in Spanish, are available online(c).
Karl Juergen Hepke has written an extensive paper (in English) on the work of Bonsor(b).
