poor but a coordinated set of changes, designed by their "Universal Method" could make large changes without catastrophic perturbations of the rest of metabolism. Biochemical interest in the ideas expressed in "The control of flux" started to grow in the 1980s, particularly with its experimental applications in Amsterdam to oxidative phosphorylation, urea synthesis and gluconeogenesis. At this time, because the theory of Kacser and Burns and the simultaneous but independent work carried out by Reinhart Heinrich and Tom Rapoport in Berlin were compatible, a common terminology and set of symbols was agreed for the new field of Metabolic Control Analysis. Later life On retiring from lecturing in 1988 he became a Fellow of the University of Edinburgh. Kacser was an active geneticist/biochemist right up until his death. At the time of his death, Henrik still ran an active laboratory, had two large grants supporting his work and continued to produce original scientific ideas. He was elected to the Fellowship of The Royal Society of Edinburgh in 1990. His proposers were W. G. Hill, Alan Robertson, Charlotte Auerbach, Geoffrey Beale and Douglas Scott Falconer. In 1993 he received an honorary doctorate (DUniv) from the University of Bordeaux. He died in Edinburgh on 13 March 1995. Family Henrik married twice: firstly in 1947 to Beatrice McConkey (d. 1969); secondly in 1978 to Elaine Daffern.
