to the new Royal Melbourne Hospital, which opened in 1942. Under Kellaway's directorship, the institute came to achieve international recognition as a centre for excellence in medical research by the outbreak of World War II. Sir Frank Macfarlane Burnet was the institute director between 1944 and 1965, and he brought the institute to international prominence for virological research, especially influenza, and then for immunology. Such was the nature of Burnet’s achievement that he was awarded the Nobel Prize for Medicine in 1960 with Sir Peter Medawar for the discovery of immunological tolerance. Sir Gustav Nossal succeeded Burnet as director in 1965, aged 35. Under his stewardship, the institute grew in size and scope, with its scientists making important discoveries in the control of immune system responses, cell cycle regulation and malaria. During this time, the group led by Professor Donald Metcalf discovered and characterised the colony-stimulating factors (CSFs), which have benefited more than 10 million cancer patients worldwide. Between 1996 and 2009, it was led by Professor Suzanne Cory. Since July 2009, Professor Doug Hilton has been the director of WEHI. In the lead up to its centenary in 2015, the Walter and Eliza Hall Institute underwent significant building redevelopment. A new west wing was built in 2012, nearly doubling the institute's size, funded by the Victorian and Australian Governments and The Atlantic Philanthropies. In 2020, the institute rebranded itself to the simpler name WEHI, and updated its motto to Brighter together. Research The institute focuses solely on medical research, centered around: Cancers (such as leukaemia, lymphoma, multiple myeloma, breast cancer and ovarian cancer) Inflammatory or autoimmune diseases (such as type 1 diabetes, coeliac disease, multiple sclerosis and rheumatoid arthritis) Infectious diseases (such as malaria, HIV and hepatitis B and C) The institute is organised into the following 14 divisions (with current Division Heads in parentheses): ACRF Chemical biology (A/Professor Isabelle Lucet) ACRF Cancer and stem cells (Professors Geoff Lindeman and Jane Visvader) Bioinformatics (Professors Gordon Smyth and Melissa Davis) Blood Cells and Blood Cancer (Professor Andreas Strasser) Clinical Translation (Professor Clare Scott and Professor Ian Wicks) Epigenetics and Development (Professor Marnie Blewitt and Professor Anne Voss) Immunology (Associate Professor Daniel Gray and Professor Phil Hodgkin) Infectious Diseases and Immune Defence (A/Professor Wai-Hong Tham and Professor Marc Pellegrini) Inflammation (Associate Professor James Murphy) Personalised Oncology (Professor Peter Gibbs and Associate Professor Marie-Liesse Labat) Population Health and Immunity (Professors Melanie Bahlo
