Tribute to Prof Keith Boardman, AO, FRS, FATSE, FAA on his 100(th) birthday (August 16(th) 2026).

Keith Boardman and Jan Anderson achieved the first convincing separation of Photosystem I and Photosystem II particles, isolating distinct photosynthetic components in their 1964 work.

• Why it matters: Separating Photosystem I from Photosystem II was a key step needed to study photosynthesis in a more modern, mechanistic way.
• What they did: While leading CSIRO’s Division of Plant Industry in Canberra from 1960–1977, they used biochemical isolation methods to separate the two photosystems, reporting the first convincing separation in 1964.
• The result: Their success helped bring photosynthesis research into the modern era and supported Boardman’s later influential scientific leadership and recognition, including major fellowships and honors.
