John Sattler, Australian rugby league player (died 2023)

John William Sattler was an Australian professional rugby league footballer played as a prop in the 1960s and 1970s. He captained South Sydney to four premiership victories from 1967 to 1971 and who played four Tests for Australia – three as national captain. Known as "Satts", he was one of the hardmen of Australian rugby league and was regarded as an aggressive on field player but a softly spoken gentleman off the field – hence his other nickname "Gentleman John". His son Scott Sattler also played professionally, winning a premiership with the Penrith Panthers in 2003.
