Westmead Hospital mechanical fitter John Jensen (or JJ as he was affectionately known) retired in July after more than 39 years in the maintenance department.
His colleagues describe him as a quality tradesman, precision machinist and excellent welder.
John was responsible for maintaining production and the distribution of medical air throughout the wards and departments of the hospital.
He repaired pumps, sterilisers, pan sanitisers and other equipment and had the ability to design, manufacture and invent equipment that did not exist, to make the impossible possible.
JJ is enjoying life in retirement in the country town of Cowra by regularly playing golf and doing a few odd jobs here and there to keep himself busy.
