Abstract
Contributions by the Peimberts have been fundamental in establishing ideas concerning both the properties and the evolution of dwarf galaxies. I will briefly review these ideas within the context of a retrospective of the milestone paper: ``Chemical Composition and Evolution of Irregular and Blue Compact Galaxies'' by Lequeux, Peimbert, Rayo, Serrano, & Torres-Peimbert, 1979, A&A, 80, 155. This paper added pioneering spectroscopic observations of H II regions in 6 dwarf galaxies and provided much of the basis of our modern view of dwarf galaxies. Most of the conclusions and inferences remain true today, over two decades since they were written.
