"... the fullest statement Maxwell gave of his theory, his 1873 Treatise on Electricity and Magnetism, does not contain the four famous "Maxwell's equations," nor does it even hint at how electromagnetic waves might be produced or detected. These and many other aspects of the theory were quite thoroughly hidden in the version of it given by Maxwell himself; in the words of Oliver Heaviside, they were "latent" but hardly "patent." ... Maxwell was only forty-eight when he died of cancer in November 1879. ... the task of digging out the "latent" aspects of his theory and of exploring its wider implications was thus left to a group of younger physicists, most of them British."
