"Encyclopedia Dubuque is the online authority for all things Dubuque, written by the people who know the city best.”

CITY DIRECTORY. Dubuque's first city directory was printed in 1855. An industrious printer named Adams found that Dubuque had a population of 12,056. Among the business statistics were the names of eleven hotels and sixty-six STREETS and avenues. John G. SHIELDS was the MAYOR; Mathias HAM, was an alderman.
Only a limited number of the 118-page volume was printed. Within the introduction, the publishers expressed their sincere hope that city authorities would quickly see that the numbering of stores and dwellings was done along every street. The numbering along Main Street was completed by August 26, 1873. (1)
