[2] In 1954, Robertson appointed as a lecturer at the University of Leeds, where he remained for the majority of his working life.

[4] Robertson was described by his colleague John Lydon as:"a kindly, caring man…meticulous in those civilities we all intend, but do not always get round to… He took pains to make contact with newly arrived research students from abroad and worked hard to make them feel at home… at a deeper level, John Robertson was of the same mould and generation as other crystallographic social crusaders like Katy Lonsdale and J.D.

Bernal and in his own quiet way was no less determined that the universities should be centres of tolerance and social progress… For over three decades, he was more than anyone else, the human face of the School of Chemistry.
