Cincinnati's Great Disasters explores catastrophes from 1905 to 1937, featuring floods, tornadoes, fires, explosions, winter storms, and crashes. Although tragic, disasters became popular postcard subjects in the early 1900s, with many of these photograph postcards being taken by professional photographers. The postcards documenting the 1907 and 1913 floods make up the bulk of this book, as these disasters dramatically affected Cincinnatians' lives and led to innovative flood prevention planning and health initiatives. Flooding ultimately determined where businesses and residences were located in the city and was a driving force behind urban renewal of the riverfront.
