If you are an Ancestry.com member, it appears you can view the book The Centennial Anniversary of the City of Hamilton, Ohio there. I don't have an Ancestry.com membership, but I did a Google of the book's title and came up with this addy: http://content.ancestry.com/iexec/?dbid=22343&htx=BookList&ti=0 For those without Ancestry.com access, Lane Public Library has previously scanned the portion of the book that talks about various Hamilton business institutions [not the smaller local establishments, but those whose manufactured goods were shipped to other states and countries] http://www.lanepl.org/hamilton_businesses.htm These business vignettes usually give the names and background of the man or men who started the company and a mention of the chief executives of that business. Also talked about are those who took over if the business changed hands.
