The Oxford Observer began weekly publication in 1889. The paper was established by Richard Holman Parish, a prominent local businessman. Parish arrived in Oxford in 1870 and set himself up as a draper. He installed a printing press in his shop for general jobbing work. He was active in many areas of life in the community and was a strong advocate for the Oxford area.
