Count Contini-Bonacossi’s nephew and namesake – Alessandro Contini-Bonacossi – was an art historian employed by the Samuel H. Kress Foundation. He assisted his uncle in assembling and organizing the massive photograph collection – over 50,000 images – that the count used as a visual reference source for his art collecting activities. In this 1969 letter to Professor Hamilton Hazelhurst, he provides historical background on the collection and describes the work he did on it.
