John Earnshaw

John William Earnshaw (1900–82) was a self-taught Australian engineer, and inventor. He also conducted research into Australian history.^[1]

Earnshaw was born in Randwick, New South Wales, the son of a noted Sydney horse trainer and Melbourne Cup winner. He served with the Royal Engineers in France during World War I. After the war, Earnshaw undertook many dangerous travels in Papua New Guinea.

Earnshaw set up a business, Reilax Engineering, which specialised in production-line problems. The business prospered for over 30 years in North Sydney, New South Wales, until he retired in 1969. He invented a number of machines for filling metal and glass containers for the food, cosmetics, chemical and pharmaceutical manufacturing industries. For the Red Cross Blood Bank, Earnshaw devised an oscillator for separating plasma from blood. He was a pioneer of industrial chromium plating in Sydney. His oil-free compressor was widely used on tractors, graders, road rollers and similar earthmoving equipment.

Earnshaw's spare time was filled with research into forgotten aspects of Australian history, uncovering new information about the Scottish Martyrs,^[2] judge-advocate David Collins, early Sydney cabinetmakers,^[3] and John George Lang – the first Australian short story writer. He authored several biographies for the Australian Dictionary of Biography.

In 1944, Earnshaw was a co-founder of the Book Collectors Society of Australia, and a lifelong supporter of the society.
