1845 14 Yates Street, Schenectady, New York.
P. C. Ransom was recorded in one advertisement that appeared on August 19, 1845 in The Schenectady Cabinet, or Freedom’s Sentinel (Schenectady, New York). P. C. Ransom, Daguerreotype Artist, Has opened a convenient room at No. 14 Yates st. Schenectady, where he is prepared to execute at any hour of the day, Miniatures, of individuals and family groups, with all the late improvements, in a style not surpassed. Miniatures taken by this new process are of an entirely different character from those produced by the old process, as it gives the likeness nearer the color of life, obviates the death-like appearance which has hitherto been the objection to Daguerreotype Miniatures, and also renders the impression entirely permanent on the plate. Ladies and Gentlemen are respectfully invited to call and examine, and sit for their likenesses if they choose, by way of experiment.
P. C. Ransom is not recorded as being active in Schenectady, New York in other photographic directories. Craig’s Daguerreian Registry does list a Porter C. Ransom in Troy, New York in 1847-1849, it is possible they are the same person.
