 Although unable to travel to Europe in 1970, Andrews became able to do so in 1976, when he was due to attend a European conference in Strasbourg, near the France-Germany border.He obtained permission and support from Slater, from the Trinity College library, and from his professor, Ben Noble, to visit Cambridge after the conference, in order to investigate the "invaluable" unpublished writings of Watson "et al".Noble agreed, adding that if he could attempt to find a lost paper by James Clerk Maxwell at the same time, it would be appreciated.
