Aeroplane Jelly is a jelly brand in Australia created in 1927 by Bert Appleroth. Appleroth's backyard business, Traders Pty Ltd, became one of Australia's largest family-operated food manufacturers and was sold to McCormick Foods Australia, a subsidiary of United States corporation McCormick & Company, in 1995. Aeroplane Jelly is the market leader in Australia's jelly market, with over 18 million packets sold annually. Strawberry is the best-selling flavour. Aeroplane Jelly ran a successful advertising campaign featuring a jingle that has become part of Australian culture. It is one of Australia's longest-running jingles, recorded in 1937 featuring the voice of five-year-old Joy King. It was played on radio over 100 times per day in the 1940s. The jingle was added to the National Film and Sound Archive's Sounds of Australia registry in 2008. History Adolphus Herbert Frederick Norman Appleroth, known as Bert Appleroth, was a tram conductor who created jelly crystals using gelatine and sugar in his bath. He sold these jelly crystals door-to-door, using his tram route to transport him around Sydney. In 1917, Appleroth rented premises to manufacture his jelly, then formed a company with Albert Francis Lenertz named Traders Pty Ltd in 1927. Planes were considered new and exciting at the time, so aviation fan Appleroth named the brand Aeroplane Jelly. Appleroth used a Tiger Moth plane to make deliveries to rural areas in 1934, and his publicity stunts and Aeroplane Jelly's advertising campaigns made the jelly a national icon, like Holden and Vegemite. Appleroth's company, Traders Pty Ltd, was run by his son, Bert II, then grandson, Bert III, and ownership passed to Bert III's wife Val when he died in 1985. According to Traders' managing director, Hugh Knox, the Appleroth family were friends with a former managing director of McCormick & Company, which opened up negotiations between the parties. Aeroplane Jelly was sold to McCormick Foods Australia in 1995, the Australian subsidiary of the United States-based McCormick & Company. The first Aeroplane Jelly factory was located in Paddington, New South Wales, a suburb of Sydney, then manufactured in West Ryde for 33 years. In 2006, McCormick Foods Australia moved production of Aeroplane Jelly to Clayton, Victoria, to centralise its manufacturing operations in Victoria. Advertising The Aeroplane Jelly jingle was composed by Albert Francis Lenertz (1891–1943), Appleroth's business partner. The jingle was a re-working of Lenertz's earlier political jingle in tribute to Australian Prime Minister William Morris
