3 Cottrell from 1959 on his PhD on fracture of steels and therefrom until 1990 the Cottrellinspired Knott Group was extremely active in our discipline. Indeed Knott is arguably Cottrell’s foremost research student and co-worker who has made massive contributions (including as ICF President) and after over twenty years at Cambridge from 1990present transferred his group back to Cottrell’s alma mater Birmingham very successfully. Arguably the most lasting contribution of Cottrell was through his years at Cambridge especially as Goldsmiths’ Professor. Indeed a new “Cottrell Chair” is planned to be established at Cambridge in 2014 via especially contributions from former students of Cottrell. Probably the most prominent successor to Cottrell as Goldsmiths’ Professor is Colin Humphreys who held this prestigious Chair from 1991-2008. Evidence suggests that the most significant research accomplishment (2000-2013) of Humphreys in the Cottrell tradition is on crack prevention/stress management in the manufacture of GaN for LED applications. Humphreys has also been Director of the Rolls-Royce Technology Centre at Cambridge since 1994 focussing on nickel-base superalloys with many outstanding achievements of this Rolls-Royce Centre. This is linked also to his appointment in the early 1990’s of Julia King to replace John Knott when he left Cambridge for Birmingham and to be Deputy Director of the Rolls-Royce Centre, later joining Rolls-Royce as Director of Materials in Derby. King was a key appointment of Humphreys as Goldsmiths’ Professor just as Knott was a key appointment of Cottrell himself when Goldsmiths’s Professor. A key Cottrell Legacy is also the many world-class and very influential series of textbooks and programmes of Mike Ashby on Materials Design. In addition to ICF and the new World Academy the chief guardians ongoing of the Cottrell Legacy are Knott, Humphreys and Ashby and in a further paper we shall explore these legacy aspects of Cottrell. There is an extensive oral interview of Cottrell in the archives of the British Library which covers his whole career anecdotally and since Cottrell’s death there have been very many tributes and obituaries published including an extensive review by John Knott which is available now on the www.ICFWASI.org website. Accordingly there is no need to here delve in to the very many books and works by Cottrell, his great fount of ideas that inspired generations of researchers and transformed various realms of science and engineering. Our task is to examine the international inspirations and legacy of Cottrell especially in the discipline of our newly burgeoning World Academy of Structural Integrity and the contribution to Society. Documents from Trevor Churchman, Harold Paxton, Jacques Friedel & others have come to light via ICF and Ron Armstrong is assembling a parallel paper to our own to thereby create a debate in a Cottrell Forum at ICF13. So that this paper is simply one short introduction to this Forum which is additionally designed to address the further metamorphosis in comprehensive substance of the new “Academy” through ICF14 in Rhodes in June 2017 and to ICF15 in Vancouver in July 2021 as a ten year project. Already noted is the new Academy Internet Library launched in Turin, Italy in August 2012. The Gold Medal prestigious awards in the names of the three most significant creators of ICF based on a micro-macro vision, Takeo Yokobori, Alan Cottrell and George Irwin were established at ICF12 in Ottawa in July 2009. Building on the original ICF Interquadrennial in Beijing in November 1983 we now have a comprehensive programme of several Interquadrennial Conferences each year. As well we now have a global network of MoU agreements with various societies and institutions. There are plans at ICF13 to establish a programme of “ICF-WASI Regional Directors” – perhaps as
