Marshall (Hal) Davidson Hatch AM (born 24 December 1932) was an Australian biochemist and plant physiologist. He was the chief research scientist at the CSIRO Division of Plant Industry in Canberra. He is a Fellow of the Australian Academy of Science, a Fellow of the Royal Society, a Foreign Associate of the US National Academy of Sciences and was awarded Honorary Doctorates from the University of Göttingen and the University of Queensland. In Australia, in 1966, he elucidated, jointly with Charles Roger Slack, the C4 pathway for the fixation of carbon, which is also sometimes known as the Hatch-Slack pathway. He is now retired.

Marshall Hatch in the context of C4 photosynthesis
C4 carbon fixation or the Hatch–Slack pathway is one of three known photosynthetic processes of carbon fixation in plants. It owes the names to the 1960s discovery by Marshall Davidson Hatch and Charles Roger Slack.
C4 fixation is an addition to the ancestral and more common C3 carbon fixation. The main carboxylating enzyme in C3 photosynthesis is called RuBisCO, which catalyses two distinct reactions using either CO2 (carboxylation) or oxygen (oxygenation) as a substrate. RuBisCO oxygenation gives rise to phosphoglycolate, which is toxic and requires the expenditure of energy to recycle through photorespiration. C4 photosynthesis reduces photorespiration by concentrating CO2 around RuBisCO.

Charles Roger Slack FRS FRSNZ (22 April 1937 – 24 October 2016) was a British-born plant biologist and biochemist who lived and worked in Australia (1962–1970) and New Zealand (1970–2000). In 1966, jointly with Marshall Hatch, he discovered C4 photosynthesis (also known as the Hatch Slack Pathway).
