Over the years stamps have featured numerous unpleasant dictators, corrupt politicians, over-rated entertainment celebrities and overpaid sportsmen, but sometimes people of true worth find their ways on to postage stamp designs. On 10 April 2012, Australia issued a set of 5 gummed stamps and 5 self-adhesive coil stamps which commemorated medical doctors of great note and great worth. All 5 values were in the domestic postage rate of 60c and the designs featured Dr. Jane Stocks (1872 - 1939) who, with her sister, founded the Queen Victoria Hospital in Melbourne and worked to improve the health particularly of children of the time. Dame Kate Campbell (1899 - 1986) was a paediatrician who demonstrated the link between blindness in premature babies and oxygen levels in neonatal incubators. She was awarded the OBE in 1971.
