E. R. Watts and Son, makers of theodolites and other surveying instruments, of 123 Camberwell Road, London. The company was established in 1856 by Edwin Watts at twenty-three he had saved £100 from his earnings to start the business with his staff consisting of one boy and later Alexander Clarkson as an apprentice with the workshop a small room over a Bemondsey stable. Watts' first order was from Negretti and Zambra for a mining dial Alexander Clarkson In the early days the firm worked mainly on marine compasses. Edwin Watts would go down to the Docks to adjust the compasses once they had been installed on the ships. In May 1873 the business moved to larger premises a house with a garden. The workshop was also the home of Mr and Mrs Watts and their five sons and three daughters. By now there were fifteen to twenty men employed by the firm. The company were commissioned to supply the Theodolites and Levels for the construction to the Canadian Pacific Railway in 1881. Towards the end of the century, the firm began to make heliographs continuing to produce them for the government until just before the Second World War when by agreement assigned their manufacture to another firm. 1904 The first dividing engine was completed by George William Watts. It was so remarkable an instrument at the time and for years afterwards, In 1907 Arthur Ames went to Canada and started an organisation in Winnipeg in 1909 this became a separate company called E. R. Watts and Son Ltd. of Ottawa. This firm developed considerably and was eventually with the co-operation of three other instrument companies (Cambridge Instrument Co, Ross, and Negretti and Zambra), were reconstituted as ”Instruments Ltd” of Ottawa and Toronto. During the next ten years, the firm expanded greatly to include glass grinding, leather work, dividing and engraving, testing, adjusting and packing. This expansion was continued during the First World War when workshops were completed and the machinery installed and running within eleven weeks from the start of construction. During the war, a Sergeant Coles, among the rats, lice and mud of the trenches, fitted various bits of scrap into his cocoa tin and made the first Flash Spotter for plotting the positions of enemy guns. Coles was rushed home to the firm's factory where he and George William Watts designed a spotter not made out of a cocoa tin and as a result, the Watts Vertical Force Variometer was developed during WWI. Other Watts instruments made in the First World War included the Light Mountain Theodolites which were taken on Mt Everest expeditions. In 1919 ER Watts and Sons was incorporated as a limited company and in 1939 G. A. Whipple joined the Board of Directors. Shortly afterwards, Frank Charles Watts died having been Chairman of the firm for over 37 years and seen it through the First World War with all its expansions and difficulties. He was succeeded by his brother George William Watts with the vacant post of Managing Director being filled by G. A. Whipple. During the Second World War, the company expanded further and the number of employees rose to well over 1,300. In 1946 Watts acquired 78% of Adam Hilger and the microscope maker James Swift and Son Who were Manufacturers of Theodolites, Levels, Alidades, Meteorological Instruments, Variometers, and many other types of scientific instruments Then in 1948 the company amalgamated with Adam Hilger as Hilger and Watts which was then incorporated as a public company.Naval Rangefinder with a vertical wooden handle, and an arrangement of optical lenses.

John and Emma Propert emigrated from England in 1877 and settled in New South Wales . Several of their 11 children became talented inventors, designing items ranging from kitchen utensils to coaches and later pop-up caravans. One of the most successful was Charles, who designed and built kitchenware over many decades. His earliest invention was irrigation equipment including patenting the common backyard rose sprinkler. Propert became a household name when he began making a wide range of kitchen implements for decades including flour sifters and chip cutters. By the 1970s Propert was Australia’s leading brand of kitchen and bathroom scales. By far the most successful product was a ball-driven egg beater, trademarked as the Ezy Whisk or Swift Whisk. In the days before electric beaters, the Ezy Whisk and Swift Whisk were market leaders and were exported world-wide. Charles Propert and his son Bertram manufactured more than a quarter of a million egg beaters a year in the early 1950s which explains why so many are still in use today.These items are significant because they were widely used throughout Australia in the 1950s by a major Australian manufacturer.Two Propert's kitchen appliances - a stainless steel Whistling Egg Timer and a Swift Whisk BeaterOn Egg Beater : A PROPERT PRODUCT MADE IN AUSTRALIA PATENT BALL DRIVE SWIFT WHIP STAINLESS STEELkitchen utensils, propert kitchen appliances
