Dr. William Isaac Spencer
Dr. William Isaac Spencer, Napier's third Mayor, held office continuously for three years and a half. He was an army surgeon, attached to the 18th Royal Irish Regiment, and came to New Zealand with the troops that took part in the second Maori war. Subsequently, on account of his eminent qualities as a surgeon and physician, he was induced by the people of Napier to resign his commission, and to practise his profession in their town. Dr. Spencer was also a diligent scientist, who kept well abreast of the times in all matters of science, and who gave occasional lectures on scientific subjects. Two of his sons are following their father's profession, and a daughter is the Lady Principal of the Napier Girls' High School. Dr. Spencer died at Napier in the year 1897, at the age of sixty-five years.
