T G Harrison was an early member of the Oakland City Council. He represented the 4th Ward in 1885 and 1886, and was a Republican.1
One of Harrison's elections was the source of much controversy, as it appears he tried to have it rigged. Men waited in line for up to an hour to vote, and 39 were still waiting when the polls closed.4
It appears he owned, along with S B Boyce, "Harrison and Boyce," a wholesale and retail grocery store on 473 and 475 12th Street.2 He was the Street Superintendent in 18933 and was almost impeached after the Department of Public Works turned in bad work on 8th Street.5 His wife is frequently mentioned in context of Oakland society affairs.
