Obituary notice from The Queenslander, Brisbane, Saturday, 21 September 1889: "HANN--On the 5 April, William HANN, of Maryvale, North Queensland, accidentally drowned whilst bathing in the sea at Townsville, leaving a wife and two daughters to mourn the loss of an affectionate husband and loving father, aged 52."
He was certainly a treasured teacher on Brisbane's School of Art, later a 'Drawing Master' at Brisbane Girls Grammar School, next to his work as a painter and as an illustrator (most notably for the Queenslander, and for 'Bobby' Byrne's weekly the Queensland Figaro).
'J.A. Clark', as he commonly signed himself, was responsible for the famous 1880 oil painting 'Panorama of Brisbane from Bowen Terrace' and also for all of the famous front pages and title-illustration used in the Queenslander (see illustration on this page) during Lukin's managing editorship of that Journal from 1873 to 1880.
