Observations of spectroscopic double stars with long baseline optical interferometry have resolved many pairs, allowing their orbits to be measured and stellar masses and distances to be derived. A number of these measurements have accuracies worthy of comparison with high quality results from eclipsing binaries, thus able challenge stellar evolution models. I will review the contributions, and also show recent results, among them observations of massive O-stars and multiple systems
