WEHI (), previously known as the Walter and Eliza Hall Institute of Medical Research, and as the Walter and Eliza Hall Institute, is Australia's oldest medical research institute. Sir Frank Macfarlane Burnet, who won the Nobel Prize in 1960 for his work in immunology, was director from 1944 to 1965. Burnet developed the ideas of clonal selection and acquired immune tolerance. Later, Professor Donald Metcalf discovered and characterised colony-stimulating factors. , the institute hosted more than 750 researchers who work to understand, prevent and treat diseases including blood, breast and ovarian cancers; inflammatory diseases (autoimmunity) such as rheumatoid arthritis, type 1 diabetes and coeliac disease; and infectious diseases such as malaria, HIV and hepatitis B and C. Located in Parkville, Melbourne, it is closely associated with The University of Melbourne and The Royal Melbourne Hospital. The institute also has a campus at La Trobe University. The Director of WEHI, since July 2009, is Professor Doug Hilton , a molecular biologist. History The institute was founded in 1915 using funds from a trust established by Eliza Hall following the death of her husband Walter Russell Hall. The institute owes its origin to the inspiration of Harry Brookes Allen, who encouraged the use of a small portion of the charitable trust to found a medical research institute. The vision was for an institute that 'will be the birthplace of discoveries rendering signal service to mankind in the prevention and removal of disease and the mitigation of suffering.’ In April 1915 the new Melbourne Hospital agreed to provide a home for the Walter and Eliza Hall Institute of Research in Pathology and Medicine, as it was then known. A few weeks later, the new institute's director-designate, Gordon Mathison, suffered fatal wounds in the ANZAC Battle of Gallipoli. The floors set aside for the institute in the grounds of the old Melbourne Hospital were given over to the Commonwealth Serum Laboratories in 1918 until a new director could be secured at the cessation of hostilities. Sydney Patterson was appointed the first director and took up his post in 1919. Patterson resigned and returned to England in 1923. He was followed by Charles Kellaway for the critical years 1923-44. Kellaway formalised research streams, supported aspiring local researchers, built up public benefactions and secured the first Commonwealth grants for the institute's researches. He also oversaw the plans and construction of the first separate institute building adjacent
