Herbert Peter Jackson was brought up in South Yarra, Melbourne, Victoria and became a hairdresser in 1950, and then designer in 1953. He gradually transformed his family's mixed business into a specialist mens wear shop, and later opened a number of branches. His early clients included celebrities such as Graham Kennedy, Bert Newton and Philip Brady. He introduced store credit cards to Australia.He was influenced by London's Carnaby Street, and he became a leader in the fashion stakes in Melbourne in the 1960s.
Despite early success, his business failed in 1976. He moved to Queensland with his two sons and became a house painter. Returning to Melbourne, he joined a clothing manufacturing business and dabbled in real estate. His siblings David and Olga revived the Peter Jackson business, and in 1993 Peter returned to personal involvement in it. He became the public face of the business, and made his own television advertisements.
Although he was not personally interested in football, his company sponsored the Footscray Bulldogs team because his third wife is a bulldog breeder.
Jackson died of prostate cancer at Knox Private Hospital in Wantirna, Melbourne on August 1, 2008. He suffered with the disease for two months before his death. He is survived by his third wife, Brenda, his children Lee, Peter, Steven, Mandy, Lisa, Natalie and Morgan, his sister Olga, and seven grandchildren.
