Gunnar Nordstrom constructed the first relativistic theory of gravitation formulated in terms of interactions with a scalar field. It was an important precursor to Einstein's general theory of relativity a couple of years later. He was also the first to introduce an extra dimension to our spacetime so that gravitation would be just an aspect of electromagnetic interactions in five dimensions. His scalar theory and generalizations thereof are here presented in a bit more modern setting. Extra dimensions are of great interest in physics today and can give scalar gravitational interactions with similar properties as in Nordstrom's original theory.
