A former Warwick Academy school headteacher, known for being a “strong disciplinarian” and having a “strong strength of character”, has died aged 83.Bermuda-born Joseph (Zacky) Marshall served as Warwick Academy headteacher from 1972 to his retirement in 1987.He will be remembered for steering the school through years of progress changing it from a typical British grammar school, to one offering a more liberal arts education.Dr Marshall leaves behind wife Betty and children Shane, Tim, Chris and Kim.Son Dr Shane Marshall said: “My dad had a PhD in physical education and so he was always very interested in health and very interested in exercise.“I am sure one of the things he will be best remembered for were the high standards he set at Warwick Academy and the importance he placed on politeness and discipline; some attributes that a lot of people these days wish there was more of around.“He was a wonderful father. I have got two brothers and a sister and we all loved him and we will miss him deeply as will his many grandchildren and great-grandchildren.”Gabriel Rodriguez, who served as deputy headteacher under Dr Marshall, described him as a person who “consulted widely before making a decision, but having done so, stood by it and was very strong that way”.He said Dr Marshall, a former Warwick Academy student, introduced many new ideas to the school after returning from the US, where he had seen trends happening that he foresaw would later impact Bermuda.“So he created rules to try to adjust to it before it happened. He tightened things up considerably in a way that made the place a lot more secure.“He definitely was a very strong headteacher. With Dr Marshall, rules were rules and they were the same for everyone. Everyone knew where they stood. He was strict but always fair.“He did a lot for the school in that sense. The school was fairly successful before he came, but he made sure it continued in that vein.”Mr Rodriguez said Dr Marshall was headteacher as the school went from having two classes per year to four, and changed from having a primary school to solely being a secondary school. The school, which left the public school system in the mid-1990s, now educates pupils from the age of five to 18 again.Mr Rodriguez said he respected Dr Marshall both personally and professionally and added: “We got on very well.”They both shared a favourite past-time of woodworking, he added.Current Warwick Academy principal Maggie McCorkell said the school family was “very saddened by the news of the passing” and the “Warwick Academy family extends our condolences and sympathies to his wife Betty and all the Marshall family”.Flags at the school will be flown at half mast this week as a symbol of respect for Dr Marshall.
