Ernst Johannes Hartung was a chemist and astronomer. Educated at the University of Melbourne (BSc 1913, DSc 1919), he became lecturer in 1919, associate professor in 1924, and succeeded Rivett as chair of chemistry in 1928, remaining in this position until 1953. Hartung?s lecturing style surged with enthusiasm and he employed the use of screen projections to demonstrate chemical phenomena to large undergraduate classes. In 1935 he recorded Brownian movement in colloidal solutions on 35 mm cinefilm, which was later copied onto 16 mm film for the Eastman Kodak Co. World Science Library. This can be viewed in the Chemistry laboratory. He researched the photo decomposition of silver halides, and was awarded the David Syme Prize in 1926. He devoted time to the design and construction of a large, new chemistry building for the School of Chemistry (built 1938?1939). During World War II he was approached by Professor Thomas Laby, chairman of the Optical Munitions Panel, to chair the advisory committee on optical materials, to produce high quality optical glass in Australia. This was successful, with large-scale production achieved within ten months at a reasonable cost. Hartung served three terms as general President of the (Royal) Australian Chemical Institute, was an ex-officio councillor of the Council for Scientific and Industrial Research, and a Trustee of the Museum of Applied Science (now part of Museum Victoria).Accessories for microscope etc.used in E.J.Hartung's work -

Microbalance
An original Kerr-Grant Microbalance, modified by E.J.Hartung This balance was invented in the chemistry department by Bertram Dillon Steele, later first Professor of Chemistry at the University of Queensland 1910-1930, in collaboration with Professor Kerr Grant, Physics. The design was widely used by other chemists, including Masson's mentor, Professor Ramsay, working in London on newly discovered rare gases (especially Radon), and Professor Hartung in Melbourne, investigating the chemistry of the decomposition of silver salts in photographic processes. The principle of the microbalance was to measure the change in density of a gas by the shift in the balancing beam due to a change in pressure of the gas in the balance case. The quartz balancing beam was made by Bertram Steele who was particularly skilled in glassblowing. A quartz beam is the beam of the Aston microbalance based on the Steele/Grant instrument, and described by F.W. Aston, the inventor of the mass spectrometer. The bulb at one end of the beam contained a fixed amount of air, so that a change in the pressure of gas in the balance case changed the buoyancy of the beam, yielding a displacement in the beam which could be measured. By this means, differences in weight of about 10 nanogram could be measured, in amounts of up to 0.1 gram. Such differences are significant the increase in weight of a metal sample due to surface oxidation (Steele's interest) in the weight loss due to radioactive decay of Radium (Ramsay's work), and in the estimates of density change due to the isotopic distribution of Neon (Aston).

Melton City Libraries
Document, West Melton: A preview of tomorrow, c.1969
"In April 1969, the first major residential development in Melton began with the release of 148 homes for purchase. This was the first stage of a staggered release of a planned 30,000 homes for 100,000 people by 1990. The development, called Westmelton Satellite City, was described as ‘a preview of tomorrow’.101 It was the first estate built in a ‘modern’ style, with curved streets, and dozens of culs de sac. Westmelton was also the first major development in Victoria to build all the supply lines to the houses – including electricity and telephone lines – underground. The six different home designs in Westmelton were ‘specially designed for the future’, and with allotments ten feet wider than regulations required, there was plenty of ‘space for gracious living’ and for a family swimming pool. The developers of this new estate were active in promoting Westmelton as a new community within the Shire of Melton. By 1971, the Westmelton City News reported that Ian McIntosh, General Manager of Westmelton, had given away $100,000 on behalf of the company ‘to aid community projects’. This included a $72,000 donation towards building a community centre in Westmelton, and $25,000 for the shire’s Olympic-sized swimming pool. Ian McIntosh and his family moved to Melton and Ian said he was ‘very much aware of the needs of [the] Westmelton community’. By the end of 1971, Westmelton was home to 100 new families. The modern residences were obviously an appealing drawcard, but so was the country feel that characterised Melton. Mrs C. Allen, described as a ‘housewife’, said she and her husband chose to move to Westmelton because of ‘the quality homes ... and we both love the clean, fresh, natural environment that surrounds us’. Similarly, Mr W. Coxhead, insurance consultant, moved to Westmelton because of the ‘clean, fresh country air’. Accountant Mr B. Swanton echoed their sentiments, describing Westmelton as ‘far enough away from the industrial pollution carried over Melbourne suburbs by prevailing westerly winds’. The new development attracted an increasing number of young, professional couples and families, representing the beginning of a significant shift from the predominantly rural and farming community of the district’s past. The Westmelton development had four different ‘neighbourhoods’ designed to cater to a variety of different lifestyle needs. Westmelton was the first to be established, followed by Brookfield, which offered ‘superb land in a rustic setting’. Brookfield Acres offered ‘wide open spaces with lots of room for a pool and even a tennis court’ on huge one-acre blocks, while Westlake was an innovative development with ‘different sized homesites’ and ‘lakeside living’.Westmelton was the first of many residential developments that would come to play a huge role in shaping the shire in the decades to follow".A marketing brochure for the Westmelton Satellite City developmentlocal significant events, council -
Australian Nursing & Midwifery Federation
Australian Nursing Federation WorkChoices protest badge, 2006
Button distributed to and worn by Australian Nursing Federation (ANF) members and staff as part of a 2006 campaign protesting the controversial 'WorkChoices' federal industrial relations laws that were introduced by the Liberal John Howard government in 2005-2007. These laws saw the weakening of unfair dismissal laws, giving employers significantly more powers to strip existing rights and wages away. The laws were repealed following the election of an opposition Labor government in 2007 under Kevin Rudd. The 'Howard Target Nurses' campaign was featured in ANF Victorian Branch newsletters around late 2006. During this period, a number of enterprising bargaining agreements were set to soon expire, leaving nurses vulnerable to have rights stripped away under the new IR legislation. A large campaign began, with rallies across the state of Victoria. The August 2006 Branch newsletter featured images of the Tandberg 'Howard targets nurses' design on placards, shirts and badges worn by nurses at these rallies. The illustration by The Age cartoonist Ron Tandberg made reference to John Howard's involvement in wars in the Middle East throughout the early 2000s, and linked this to the 'war' on unions and worker rights.Circular yellow, red and white badge. Silver metal, plastic-coated, with safety pin fastener adhered to back. Badge printed with a blue and white ANF [Australian Nursing Federation] logo, the black text '[then-Prime Minister John] Howard targets nurses' and a Ron Tandberg cartoon of a nurse with a 'sniper target' overlay.nursing, nurses, protest, campaign, activism, activists, unions, unionism, buttons, badges, pins, campaigning, john howard, ron tandberg, labour history, australian nursing federation, workchoices, workplace relations, industrial relations -

Siebe Gorman was a British manufacturer of industrial ...This mask set is part of the North East Region Water Authority collection in the Wodonga Historical Society. Wodonga's drinking water and wastewater operations were originally managed by the Wodonga Waterworks Trust, which was established in 1897, after Wodonga became a separate shire in 1876. In 1923 a Wodonga Waterworks Trust referendum to provide funding for new infrastructure to supply more water of better quality to Wodonga was passed. This included building the Wodonga Water Tower and it was completed in 1924. It supplied water to Wodonga until 1959, when it was drained and decommissioned after the No 1 Basin on Huon Hill was completed in 1958. In 1983 the Wodonga Waterworks Trust and the Wodonga Sewerage Authority became part of the Wodonga Council. And by 1989 a filtration plant at Huon Hill was completed, which provided filtered water of improved quality to Wodonga, in accordance with the World Health Organisation’s guidelines. In 1994 the Kiewa Murray Region Water Authority took over the Wodonga Council’s water and wastewater operations, and then in 1999 the Kiewa Murray Region Water Authority combined with the Ovens Region Water Authority and became the North East Region Water Authority or NERWA. NERWA then became known as North East Water. Siebe Gorman was a British manufacturer of industrial respirators that served the mining industry, the chemical industry, and the agricultural industry from 1938 until the 1980s.
