Sir Roland Ellis "Raoul" Jacobs (28 February 1891 – 28 June 1981) was a South Australian businessman, for many years at the head of South Australia's largest brewery and hotel chain, and an active supporter of many high-profile cultural, sporting and charitable organizations.
Sir Roland was born in Adelaide the youngest child and only son of Samuel Joshua Jacobs (28 March 1853 – 4 January 1937) and his wife Caroline Jacobs, née Ellis. Samuel was well known in business and sporting circles, having been both chairman of directors of S.A.B.C. and an S.A.J.C. committee member for over 30 years. Sir Roland was educated at Geelong College and the Adelaide Shorthand and Business Training Academy, of which his father was a generous patron. Roland (who had been 2nd Lieutenant with the 16th Australian Light Horse Regiment a few years previously) volunteered for active service during the First World War, but was rejected as unfit and instead served as a training officer in Adelaide.
After a few clerical jobs, he was appointed in 1924 to a managerial position in Adelaide for brewers' supplier F. A. Henriques Ltd. This company, based in Perth, Western Australia, was taken over by Mauri Bros. and Thomson in July 1930. He was appointed assistant-manager and then manager. In July 1948 he was appointed to the board of the South Australian Brewing Company, and promptly elected managing director then chairman in 1951, which he retained until March 1965. He held the managing director's position until June 1961.
Sir Roland was a member of the Adelaide Club, a member and president of Adelaide Rotary Club in 1938, the Commonwealth Club, Meals on Wheels, Crippled Children's Association, the Adelaide Chamber of Commerce, and R.S.P.C.A.. He was a member of the Adelaide Festival of Arts board of governors, the National council of the Australian Boy Scouts Association, boards of the Royal Adelaide Hospital and Queen Elizabeth Hospital and vice-president of the SA branch of the National Heart Foundation.
