Adam Blake, Jr. (1830-1881) had a well-established career in the hotel industry prior to having the Kenmore Hotel built in 1878. The adopted son of a man who had been enslaved, Adam worked his way up in the hotel industry, and eventually opened the Kenmore, for which he spared no expense. Although Blake died before he could long enjoy the fruits of his labor, the Kenmore continued for many years, and was eventually purchased and renovated into luxury apartments.
