Since 1915, when Australian William Lawrence Bragg shared the Prize in Physics, there have been some 11 Australian Nobel Laureates.
Australia Post issued a set of five stamps to commemorate the achievements of Australian Nobel Prize winners (or Nobel Laureates). The Laureates are represented by portraits by some of Australia's most respected artists.
Lawrence Bragg (1890-1971) was jointly awarded the prize in physics in 1915 for his ‘services in the analysis of crystal structure by means of X-rays'.
Howard Florey (1898-1968) was awarded the prize in physiology or medicine in 1945 ‘for the discovery of penicillin and its curative effect in various infectious diseases'.
