Society, Historical Society of Pennsylvania, and the Covington Public 

 Library. Mrs. Richard T. Keys kindly furnished the invaluable 

 William Harkness letters, and Mr. and Mrs. Robert L. Moore con- 

 tributed much useful data on Moore & Richardson. A word of 

 thanks to my former colleague Eugene S. Ferguson for directing me 

 to the Peale-Sellers papers. For their care and interest in preparing 

 the manuscript my thanks to Mary E. Braunagel and Lillian 

 Edwards. Final appreciation is due John S. Lea, Robert C. Reed, 

 Margaret A. Pabst, Thomas C. Witherspoon, and Louise Heskett for 

 their patient and meticulous editing, which did so much to clarify 

 and reform this study. 



The inspiration for this study ultimately rests with my parents, 

 John and Christine White, whose high regard for their native city 

 stimulated my interest in the industrial beginnings of Cincinnati.
