Resumen de Alistair Day and the origins of dynamic relaxation. Part 1: Bringing an idea to life

Tristam Carfrae, Duncan Michael

• Alistair Scott Day was the engineer who invented, named, applied and developed the calculation technique ‘dynamic relaxation’.

  He died in 2015, but always a quiet man, his story had become scattered and he was in danger of being historically overlooked.

  This two-part article is intended to give an account of his life and record his exceptional achievements. The authors knew Alistair, since 1981 and 1966 respectively.
