David Martin Menne (5th February 1944 - 4th November 2003) was a visionary South African - Australian chemical engineer, who developed pioneering technologies in the fields of metallurgy, agriculture and artificial intelligence.

Born in South Africa - at the time the world's biggest producer of gold - he was a metallurgical consultant who pioneered techniques for extracting gold (more than 100 process plants around the world have been built to designs based on his methods). After graduating in 1967 with a chemical engineering degree from Pretoria University, Mr Menne created a national program for solid and toxic waste management. He also developed the South African industry's first large applications of carbon-in-pulp technology, which he would bring to Australia after migrating to Perth with his family in 1984, a boom time for the gold industry when technology was racing ahead with each new process plant. He later became a consultant, mathematical modeller and chemicals purveyor to the industry.
