Dr Ben Reitman was a social reformer, hobo, doctor, lover of Emma Gold
man and anarchist activist in the United States in the late 19th and e
arly 20th centuries. In 1910 he gave a lecture in New York titled ''So
cial Geography'' in which he used a diagram picturing an imaginary pen
insular, ocean and archipelago illustrating a series of points relatin
g to the exclusion of a number of groups in Chicago during the early t
wentieth century. In this paper I consider the exclusion of Dr Reitman
's unconventional knowledge of the excluded from mainstream social sci
ence. Remarkably, Reitman's Peninsular of Submerged Hope points to the
poststructuralist cultural/social geography of the 1990s, emphasising
marginalisation, amplifying marginal voices and pointing to the force
s that produce marginalisation in the first place. (C) 1998 Elsevier S
