Jim Menter was a man of many parts: he excelled as a scientist, industrialist and academic administrator. He was well read and hadwide ranging interests in the Arts—in the words of one of his colleagues at Queen Mary College, he was a true Renaissanceman.
His most important scientific contributions were the first direct observations of crystal lattices by transmission electron microscopy and the first observation of an edge dislocation within such a lattice. The work was published in the Proceedings of the Royal Society in 1956 (11)*. This paper had a profound impact on electron microscopy of crystals and, by virtue of the direct observation of dislocations, made an important contribution to the general acceptance of the dislocation theory of crystal plasticity.
