Jake MacMillan

He "became renowned for his work on isolating, naming and determining the chemical structure of gibberellins, which regulate growth and influence processes such as stem elongation and germination".

His father, John,[2] like his grandfather, was a “signalman on the old London Midland and Scottish (LMS) railway line”,[3] and his mother, Barbara (née Lindsay) came from a farming background.

He went on to obtain a postgraduate studentship from the Department of Scientific and Industrial Research (DSIR), enabling him to continue as a PhD student in Glasgow.

[3] He joined a small, high-powered group of organic chemists and microbiologists at The Frythe[6] in Welwyn, aiming to find potential pharmaceuticals in fungi.

A multidisciplinary team was involved in the effort, with Margaret Radler discovering that immature seeds of runner beans (Phaseolus multiflorus) were a relatively rich source (ca 0.25 μg/g).

His final years at ICI were spent in overseeing the move of Akers staff to the newly-established Pharmaceutical Division at Alderley Edge, and the transfer of The Frythe to its new owners, Unilever.

He and a colleague, Bob Binks, worked on the relatively new technique of gas chromatography (GC) in combination with mass spectrometry GC-MS to identify a range of gibberellins.

The results were presented at the Sixth International Conference on Plant Growth Substances at Carleton University, Ottawa, in 1967, and published in 1969.
