John Ginty (fl. c. 1910 – c. 1925) was a San Francisco based banker, civil servant, and railroad man. Ginty initially wanted to become a journalist and left his home at just 14 in pursuit of that career. He took work at a printing office but found, to his consternation, that the work was not for him. Instead he mastered the telegraph and took work in the railroad industry as a station agent, then superintendent clerk, and finally train dispatcher. He followed the railroad to San Francisco, settling there in 1868, and transitioning into banking. He worked in the San Francisco Office of the Assessor under Washington Dodge before assuming the position of Chief Assessor, formerly held by Dodge, in August of 1912. Ginty was known among his peers as 'quiet and unassuming.' Little else is known of his life.
