Abstract
Nearly 4 years ago, two teams of observational astronomers reported that hi gh-redshift Type Ia supernovae are fainter than expected in a decelerating or freely coasting universe. The radical conclusion that the universe has b een accelerating in the past few billion years, possibly because of a nonze ro value for Einstein's cosmological constant, has gripped the worlds of as tronomy and physics, causing a flurry of new research. Having participated on both teams (but much more closely with one than the other), here I provi de a personal, historical account of the story.
