At the time Chandra was launched, we knew of only two dozen super soft x-ray sources (SSSs). Furthermore, the natures of most had not yet been understood. Chandra observations of more than 300 galaxies has discovered >1000 SSSs and established the statistics of the class while at the same time identifying its most extreme and intriguing members. We have discovered slightly harder sources, quasisoft x-ray sources (QSSs), and also much more luminous soft sources than any known in our Galaxy or in the Magellanic Clouds, with L in the range 10^{40}-10^{41} erg/s. Beyond the numbers, these observations have taught us a great deal about binary evolution, nuclear burning on white dwarfs and the progenitors of Type Ia supernovae, and models for intermediate-mass black holes. We review the revolution in our understanding of these sources made possible by the first decade of Chandra.
