Stirrer, used in Optical Glass work, Hartung & associates, 1941 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).

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).

W. Thorne architect of Albury designed the library building and the plan was approved in June 1915 The building contractor was J. W. Cochrane of Albury. The land was purchased from Mr. Walter Huon. On the 28th July 1915 the Shire President, Councillor Beardmore, laid the foundation stone for the building that would become the Wodonga Public Library. Almost 12 months later, on the 8th March 1916, the library was officially opened. It was the pride of Wodonga. The Shire Council closed their doors for a brief period so that all staff could attend the opening and the teachers and children of the local schools also attended. Councillor Beardmore declared that “it was an asset that would return a profit- not in pounds and shillings and pence but in the development and furnishing of the minds and lives of our young people”. It was known as the Beardmore Library. The Wodonga Athenaeum, in an out of the way location, had closed in 1914 after continuing reports of a lack of funds and the proceeds of the sale of the building went towards the building of the new library. In 1915 the library building committee started to put together a building fund for a new library. The library, situated at 78 High Street, was funded almost exclusively by the public. The books from the Athenaeum were presented to the library committee at the opening in 1916. The new library was both a place for education and recreation, a communal space to socialise, which also boasted a billiards room downstairs. In March 1970 construction of a new Civic Centre which included a library began in Wodonga. WIth its completion the following year, the original library was closed down. The building was vacant for some time and deteriorated badly. It was later purchased by Peter Middleton, who extensively restored the building. It is now the home of Middleton's Carpets.These images have local significance as they document an important building in Wodonga.2 photos - one black and white and one in colour of the same brick building. The first photo is of the building when it served as the Wodonga Public Library. The colour photo was taken approximately 60 years later.Photo 1 - In Brickwork above the door: PUBLIC LIBRARY Photo 2 - Above door: MIDDLETONS CARPETSwodonga public library, wodonga buildings

This photograph depicts flooding of Ozone Avenue in Beaumaris, located off Balcombe Road. Roads in the Beaumaris area lacked sufficient drains to clear surface water. In many cases streets were unsealed and without footpaths and some were dirt tracks. Gutters and road surfaces were made of clay and in the wetter months of winter, unsealed roads and tracks became impossible quagmires that were unnavigable for vehicles and pedestrians. In the first decade after World War II there was rapid expansion in construction of new houses in the suburb of Beaumaris. Utilities and infrastructure to support the growth of housing was inadequate and not provided for prior to the development of the area. Without rudimentary drainage, flooding was frequent. Storm water runoff, domestic sullage and septic tank overflow would form large pools and families were sometimes marooned within their homes. The frequent flooding caused isolation and hardship and residents endured difficulties with accessibility to facilities. These disadvantages had the potential to cause social issues for the new residents.Black and white photograph of flooding in Ozone Avenue, Beaumaris. The image shows floodwaters with boggy and rough terrain on an unsealed road with housing in the distance.Handwritten in blue ink: 2124 circled Handwritten in red ink: 80% Handwritten in blue ink on yellow Post-It note: Chap 6. underlined, 2194 Ozone Ave Beaumaris 1958beaumaris, ozone avenue, balcombe road, flooding, roads, infrastructure
